You may have installed the best antivirus software that money can buy and believe that protects you from malware or virus attack, but such threats can invade your digital space using the W-iFi network as well. Here are a few signs you need to keep a lookout for which indicate some unauthorized person is using your network with malicious intent.A Decrease in Wi-Fi Speed
The most obvious sign that someone outside your trusted circle is using up your Wi-Fi resources is when the speed of the Internet suddenly drops for no apparent reason. Your videos might be taking longer to buffer. Websites might be taking longer to load, and online games might be having difficulty operating.
If you feel your net speed has decreased, or your data packet is being used up much more quickly than usual, it might be because someone else has hacked into the network and is using your Internet.Changed Settings
Most hackers operate by sneaking into the network system and changing the settings to facilitate the hack. Check for signs such as:
The passwords having been changed.
The signal frequency is modified.
Your screen cursor starts moving on its own.Presence of Unknown Devices
As the network administrator, you should have access to the logs which indicate which particular devices are currently connected to the network. If you are not the administrator, find out who has that authority, and ask them to check the logs. If you find that there are devices connected to the system which are unaccounted for, it could very well be a hacker who has managed to gain access to the network.Antivirus Is Disabled
One of the first moves of a hacker who has gained access to a network is to find a way to disable the firewalls and other antivirus programs designed to keep malware out of computers. If you find that your firewall has been disabled without your knowledge, it could be the work of a hacker who has managed to invade your network.Strange Messages
Once the hacker has gained access to your network, the next step is to actually cause harm to the connected devices. You might start receiving strange messages which carry virus-infected files. These files are often shared on closed networks by a computer which is controlled by the hacker so you think it would be safe to open.
If you have the least suspicion about a message you received asking you to open an unknown file or program, even if it appears to have come from a nearby computer, take the time to check with your colleagues to find out who sent the file and confirm that they know the file can be safely opened.New Programs on Your PC
Finally, the biggest sign of a breach in security is the appearance of strange and unknown programs on your computer. These programs have been planted on your computer by the hacker and can do all kinds of damage, from leaking your personal information online to allowing the hacker to take over your device and use it to perform illegal activities.
If you notice a strange program on your PC that you don’t remember installing, do not open it under any circumstances. Find out as much information about the program online as you can, and have your antivirus program scan the files to determine if they pose a threat.Conclusion

You're reading How To Tell If Your Wi
When users find unauthorized devices on their Wi-Fi, the first thought is how to kick them off. This is certainly an important first step, but you shouldn’t stop there.
It’s also important to think about how that device got access to the Wi-Fi in the first place and what further steps you can take to secure your Wi-Fi and ensure this doesn’t happen again.
As such, we’ve detailed various ways to kick people off your Wi-Fi, as well as what you should do afterward in this article.
Perhaps your Wi-Fi has gotten very slow because too many devices are connected at once, or perhaps some of the users aren’t supposed to have internet access. Regardless of why exactly you want to do it, kicking people off the Wi-Fi is very simple – provided you have router access.
We recommend looking at the back of your router for the IP address and default login details. If you changed these in the past and don’t remember them anymore, you can restore them back to default by resetting the router.
Changing the Wi-Fi’s SSID or password causes all the devices to disconnect from the network. If the user you’re trying to kick off doesn’t know the password, changing the SSID should be enough, as they won’t be able to reconnect anyway. However, you’ll be better off setting a new password in other cases. Here’s how you can make these changes:
If you can’t currently access the router dashboard, you won’t be able to manually change the SSID or password. The reset button on the router will be handy in such cases. As stated earlier, resetting your router restores it to a factory state. This means all personalized settings, such as your Wi-Fi configurations, are erased as well.
This will leave your Wi-Fi without a password or encryption, and your router will use the default creds. So, you’ll need to configure the router and Wi-Fi again to ensure they’re secure. Here’s how you can do this:
If your router manufacturer or ISP provides programs that allow you to monitor and control devices, you can use those to kick people off the Wi-Fi without accessing the router dashboard. For instance, Netgear’s Nighthawk app allows you to do this. Here’s you can manage users on the Wi-Fi with such apps:
MAC Address Filtering allows you to control which wireless devices have network access using their MAC Address (unique hardware ID assigned to NICs). There are a couple of ways to set up MAC Filtering.
First, you can check the list of connected devices from your router. After noting the MAC Addresses of the devices you want to block, you can add them to the blacklist. However, this can be easily circumvented by faking a valid MAC Address (MAC Spoofing).
The second method, which is a bit more secure, is to only allow selected devices to access the network. This is once again done by changing the MAC Filtering mode, noting the MAC Addresses of the devices, and adding them to the whitelist.
With all this said, here are the general steps to set up MAC Address Filtering:
MAC Filtering is the most common way to manage network access, but other methods like Parental Controls, setting QOS Rules, or Bandwidth/Time Limits also work. Which methods are supported depends on the specific router in question, but most will support atleast one of these.
In terms of restricting network access to certain devices, all of these methods work similarly to MAC Filtering. They use the hardware ID of the device to limit bandwidth or restrict access based on time limits and so on. We have another article with step-by-step instructions for all these methods, but in this one, we’ll just use Parental Controls as an example:
Most routers these days can operate in both the 2.4 GHz and 5 GHz bands. These bands have various pros and cons, but for now, we’ll just cover the ones most relevant to us.
Older smartphones can often only connect to the 2.4 GHz band. The same goes for Bluetooth devices and appliances like microwaves or cameras. 5 GHz supports higher bandwidths but has comparatively lower range, meaning users will generally use the 5 GHz Wi-Fi when close to the router.
And most importantly, if the 2.4 GHz and 5 GHz bands are configured with different passwords, the user you want to kick off is likely only on one band. In such cases, disabling the problematic band can be an unorthodox but viable solution. Here’s how you can do this:
Kicking users off the Wi-Fi is often akin to treating the symptoms rather than the cause. The actual problem you’re trying to solve might be that of slow or insecure Wi-Fi, and simply kicking some people off might not solve those issues.
In order to fix slow Wi-Fi:
First, if you aren’t sure what’s making the Wi-Fi slow, a ping test can be very useful. If you get high ping or packet loss when pinging the default gateway, this indicates that the connection between your device and router is facing some problems.
Weak signal strength is the most common culprit. Ethernet is an easy fix for this, but in cases where that’s not applicable, adjusting the router’s positioning and taking other steps to boost the Wi-Fi signal will be helpful.
In the case of 2.4 GHz Wi-Fi, interference from other appliances and routers is another potential cause.
Malware on your device or router or faulty networking hardware are less common but still possible causes.
The problem could also be stemming from the ISP’s end due to things like Bandwidth Sharing or Throttling, or on the server end of the specific website or service you’re trying to access. Either way, we recommend contacting your ISP for support if you aren’t able to get your Wi-Fi up to speed by yourself.
When it comes to securing your Wi-Fi, some of the stuff we’ve covered in this article, like configuring the router and Wi-Fi securely with strong passwords and encryption or using MAC Address Filtering, are excellent ways to start. Additionally, you should also:
Disable known vulnerabilities like WPS PIN. In the same context, keeping your router in a physically secure location is also important.
Set up guest networks. This allows you to give Wi-Fi access to people while keeping them isolated from your main network. No need to give away the main Wi-Fi’s password either, win-win!
Ensure your router and device’s firewall are working and no unauthorized ports are open.
Keep your router firmware updated, and ensure your device and router aren’t infected by malware.
At WWDC ’20, Apple shocked the world and officially announced the transition from Intel. This had been rumored for years, but the time finally came for the company to begin using its own processor in the Mac. Known as the M1, this is ushering a new wave of power, speed, and efficiency that has to be seen to be believed.
This is not Apple’s first rodeo with this kind of transition, as the company went through something similar when it moved from PowerPC to Intel. However, the times have changed and there are sure to be concerns about whether that app you use every day will actually work. Luckily, Apple with the M1 chip, there is also Rosetta 2 to help in the transition.What is Rosetta 2?
Without even including the ability to run iOS and iPadOS apps, Apple wanted to make sure that users didn’t miss a beat. The Apple M1 Macs feature a piece of software that ensures that you can run all of the same apps as your Intel-powered Macs. Rosetta 2 is at the helm and is essentially an emulator that takes those “old” apps based on Intel’s architecture, and makes them compatible with the new M1 chip.
Here’s how Apple describes Rosetta:
“Rosetta 2 works in the background whenever you use an app built only for Mac computers with an Intel processor. It automatically translates the app for use with Apple silicon. In most cases, you won’t notice any difference in the performance of an app that needs Rosetta.”
Whenever an app not designed specifically for the Apple M1 chip is downloaded, you will be prompted by macOS. The prompt states that you will need to install Rosetta, and ask if you want to install it now.
Then, the app will run just like you would expect it to. However, performance may lag a little bit behind when compared to an application that has been optimized for the M1 chipset.Is my Mac using an app optimized for the M1?
So there are a few reasons why you would want to know whether an app is using Rosetta 2 or has been optimized for the M1. During the keynote announcement, Apple stated that the M1 chip can provide 3.5 times the amount of performance. GPU performance is said to be up to six times faster, while battery life is two times better than Intel’s chips.
In some real-world tests, the MacBook Air outperformed the most recent Intel MacBook Pro by a rather sizable margin. So it’s all about performance and efficiency when you’re looking at an app using Intel or Apple Silicon.How to check for a Universal app
If you want to verify that the apps that have been installed are “universal”, then there are a couple ways of doing so. Universal apps is Apple’s way for developers to state whether their apps will work with both the M1 and Intel chipsets. Here’s how you can check to see if your apps are Universal or not.
Select About This Mac.
Tap Overview in the top bar.
In the sidebar of System Report, select Applications.
From the main interface, look under the Kind category.
For those who have Setapp installed, the list may be a bit more vast than you would expect. These apps are not actually installed, but instead are made available to instantly open the Setapp application if you wish to download them.Use a third-party tool to check your apps
We’ve already detailed how you can install iOS apps to your M1-enabled Mac, even if the app is not available on the App Store. That is done with the help of a piece of software from iMazing. The company has recently launched a new, and free, tool called Silicon.
Silicon scans the applications that have been installed to your Mac, and detect whether they offer native Apple Silicon support or not. The app is free to download, and will show the entire list of apps installed. Then, you can filter the view to only see Intel-based applications (running Rosetta 2), or those developed for Apple Silicon.
If you often travel with your MacBook, you’ll probably end up connecting to more Wi-Fi networks than you care to remember. Once you’ve finished using these networks, though, it’s likely that they remain somewhere on your computer. What can you do if you want to forget one or more of these? This article will walks you through how to forget a Wi-Fi network on your Mac.Why You Should Forget a Wi-Fi Network on Your Mac
Just as with your iPhone, you may want to forget a Wi-Fi network on your Mac. One reason is that you’ll no longer use it – for example, when you replace your old router. If this is the case, keeping old details on your computer has no use whatsoever.
You may also choose to forget network for security purposes. Public networks, in particular, could pose risks in this respect – ranging from data theft to distributing malware on your device. Once again, there is no reason to keep that stored network. Signing on again would be more worthwhile than losing data to malware.How to Remove a Wi-Fi Network from Your Mac
The process of forgetting a Wi-Fi network on a Mac is pretty simple:
1. In your Mac’s toolbar, look for the Wi-Fi logo at the top of your screen.
3. Look for “Network Preferences … ” at the bottom of the drop-down list, then select it.
5. Your computer will show you a list of the Wi-Fi networks you’ve joined. Scroll down to find the network(s) you’d like to disconnect from.
7. Repeat this process for each Wi-Fi network you want to remove.How to Stop Your Mac From Automatically Remembering Wi-Fi Networks
After forgetting the networks you no longer wish to be connected to, you can stop your computer from automatically remembering networks you connect to in the future.
Follow these steps:
1. Follow steps 1 through 5 above to return to the window where you removed the Wi-Fi networks.
2. Underneath the list of Wi-Fi networks your computer has remembered, you’ll find an option that says: “Remember networks this computer has joined.” Untick its checkbox.Frequently Asked Questions 1. What happens when I forget a Wi-Fi network on my Mac?
Once you’ve forgotten a Wi-Fi network on your Mac, your computer will remove it from your list of remembered networks. You will have to re-add it to use it again.2. Can I rejoin a Wi-Fi network on my Mac after forgetting it?
Yes, you can. However, you’ll need to sign in like you did the first time you added it. It’s now like a network you have never visited before.3. Can I un-forget a Wi-Fi network on my Mac?
No. Once you’ve forgotten a Wi-Fi network on your Mac, you cannot reverse this. The only way you can connect again is if you choose it again while in range and enter the necessary security codes, as explained above.Wrapping Up
It’s easy to forget about the risks of keeping Wi-Fi networks on your Mac that you don’t use. Fortunately, though, the steps to remove any you don’t want to remain connected to are straightforward.
Along with showing you how to forget a Wi-Fi network on your Mac, we’ve also equipped you with everything you need to stop your computer from automatically remembering these in the future, giving you more control. Read on to learn how to find the best Wi-Fi channel for the 5GHz frequency.

The correct alignment of all the PC fans is crucial to cool down your overall system temperature. And some components may even start thermal throttling, giving you a lower performance than expected.
Besides this, your PC will also collect more dust if you set the fans direction incorrectly. Therefore, knowing which way the air flows from your fans is a significant piece of information that you can use to make your system perform better and last longer.
But first, let us see why the PC fan direction matters.
The PC fan direction is one factor that most beginner PC builders overlook when building a PC. However, if you make the CPU fans face the right way, you may see a drop in motherboard temperature and an increase in its efficiency.
The overall internal component’s temperature not only depends on their usage, but also on factors like airflow, internal air pressure and dust settlement. Dust settlement and airflow is a fairly common and easy concepts to grasp. So, let us talk about air pressure here.
When you insert the CPU fans, there are three possible cases of air pressure.
Positive air pressure
Negative air pressure
Neutral air pressure
Talking about positive air pressure, the number of intake fans exceeds the number of exhaust fans. This will result in the air to pass into the system mostly through a dust filter. And thus, the insides of your system will be fairly clean.
Positive Air Pressure
However, as the system does not throw out the air efficiently due to fewer exhaust fans, this may cause the system to trap heat, making the setup slightly warmer.
Negative Air Pressure
On negative air pressure, the number of intake fans is less than the number of the exhaust fan. This will create a vacuum inside the CPU case. Once this happens, air starts to flow inside the system through all openings inside the case, which means that the dust will enter through every opening and not only the dust filter.
Therefore, your system becomes dusty if you have negative air pressure.
Neutral Air Pressure
In neutral air pressure, the number of intake and exhaust fans is the same. This is an ideal scenario as the air will mostly enter the CPU from the dust filter, and the cooling is also efficient.
You can check the direction of airflow in a CPU fan in multiple ways. The stock CPU case fan comes with a plastic screw attached to it. When you attach it to a heat sink, the air will flow towards the heat sink, pulling in the air from the opposite direction.
However, determining the fan direction in most CPU coolers and case fans can be daunting. Here are a few ways you can check the CPU fan direction.
CPU Fan Direction
One simple way to determine the direction of airflow from the fans is by checking the arrows on the sides. The arrow represents the direction that air flows when the fan starts to spin.
The direction the arrow points towards is the exhaust, and the opposite is the intake.
However, not all fans have this arrow indication. If your case or CPU fans do not have an arrow, continue with the article to figure out the fan direction.
Another indication you can check is the X shaped on one of the two sides of the fan. You will see a line that goes across all the corners of the fan diagonally. Thus, making an X.
The side with no pattern is the intake, whereas the side with the X is the exhaust. However, all CPU or case fans will not have an X marking. Some will have a different pattern.
If none of the above solutions help you to determine the CPU fan direction, connect it to a power supply.
Connect the cable from the fan to the CPU_FAN header on the motherboard if it is a CPU fan or to the SYS_FAN header if it is a case fan.
Once you connect the fans to the motherboard, connect the board to a power supply unit (PSU) and turn on the motherboard.
Once the fan starts to spin, use light tissue paper to check the intake and exhaust sides.
If you cannot connect the fan to a power supply, you can always go to the manufacturer’s website and search for the product. The CPU or case fan manufacturer is usually written on the center.
Once you have the manufacturer’s name, search for the product. Some CPU fans may even have a user manual to guide you through the steps to connect it.
How To Monitor Mobile & Wi-fi Data Usage in Android Smartphone View & Control Your Data Usage With Check Data Usage
Why Do We Run Out of Data So Early?
Just as the above example of managing the time properly to finish up the work, using data also has the same concept. The issue isn’t with the data but in the way you manage it (be it mobile data or Wi-Fi data). Exactly like your working schedule, if you keep proper track of the data usage, you won’t have to worry about a thing here.
We all know how difficult it is when the internet speed goes down drastically & you just wish for the day to get over. Because accessing the Google Search homepage to look for high-quality pictures, everything starts working slower than before. Eventually, the whole world around you starts working slowly, because nowadays, the internet is our whole world. Data management is the one & only solution one can opt for to make things work smoothly.
What Do You Mean By Data Management?
Mobile or Wi-Fi data usage management would require tools that can help you manage the tracking 24*7. Because obviously, it’s not something that one can do manually so you’d require additional help to do so.
To find the solution for every problem a user encounters, Developers and service providers work very hard. This time also, in order to track the data usage, many service providers came up with apps that can help you monitor the usage. Some have been amazingly helpful and others haven’t, however, the concept worked splendidly. Same way, we took our own sweet time to research the best data usage apps and went through every possible glance. Finally, we narrowed down our research to one data usage app that’s powerfully amazing & accurate when it comes to tracking data usage. The ultimate tool that can help you get the data usage statistics accurately whenever asked is, Check Data Usage by Systweak.

F. The above screenshot in the home screen has been divided into four different categories or headers (Mobile/Wifi/Plan/Speed).
Please note: Since our whole concern is to monitor the mobile & WiFi data usage on your Android smartphone, it will be done from the above home screen only. As you can see in the screenshot, the home screen is also playing the role of Mobile header as well.
From the consumed data for the day to the accurate segregation of the apps that are eating up the mobile data, everything can be seen there. Now here comes the plan where you can put a cap on the mobile data usage and monitor the same. Yeah!! If you think your mobile data usage is exceeding way too much, you need to set up a plan to limit the data accordingly.
Start the process by tapping onto the Set Data Plan and the Check Data Usage app will lead you to the Plan tab automatically.
Once you have jumped onto the Plan tab, here you need to tap on Set Data Plan functionality (extreme bottom of the screen).
Post tapping on Set Data Plan, fill in the details that have been asked by the Check Data Usage tool.
As you can see in the above screenshot, the plan has been set up for Mobile data usage only. Also, from the Plan validity (days) you need to fill in the Data Limit as well for those specific days. Last but not least, put in the date as well from when you wish to start this plan for your mobile data usage tracking.
After filling in all the asked details, tap onto the Set Data Plan and your plan would be set up accordingly. Please know that the date you have selected for the plan to start, it will start the mobile data usage tracking automatically.
This is how you will be able to set up a predefined mobile data plan for you (days or months). Doing so will help you monitor the mobile data usage as to which app is consuming the most amount of data & should you start accessing it less. Plus, in the case or whenever your plan exceeds the defined mobile data limit, the Check Data Usage app will start giving you alerts about the same. This way, you will know that your setup plan for those many days has expired so you need to set up the data plan again now.
The above way will help you monitor, track, & set up plans for mobile data usage. Using this method will help you not to spend more money on mobile data plans, considering you don’t exceed the mobile data. And not to forget, go with the data management concept to keep things under your control.Monitor Wifi Data Usage With The Check Data Usage App
WiFi data usage is something that you opted for after going through so many data plans. It was a thorough decision that had been designed for you on a monthly or quarterly basis. So setting up a new plan under wifi data usage doesn’t make sense. Having said that, monitoring the data usage is something that one should always track, irrespective of the data sources. For example, when it comes to wifi data usage, the Check Data Usage app helps you track everything from the minimal to the maximum consumed data app/software.
All you need to do is, go to the Check Data Usage app home screen & tap onto the WiFi tab (second header from the left).
As the above screenshot shows you the data that’s been consumed through WiFi for the particular day. Just below the large-font-size numbers (consumed data), you can see the apps segregation as well. The distribution below shows you how much data has been consumed by which app. This will help you make better decisions if you think that most of your wifi data is being consumed on unnecessary apps.
Also, specifically designed to monitor your wifi data usage on Android smartphones, the Check Data Usage app is extremely useful. After going through every app, you can see which app (through wifi) is consuming the maximum data and this is how you monitor the wifi data usage.Wrapping Up
Monitoring data usage means tracking & making decisions (if needed) to keep the data usage according to your preferences. Obviously, it shouldn’t happen that all the data gets eaten by those data-hungry apps so you need to keep track of them 24*7 as well as set up data plans. Data usage tracking can help you big time while trying to identify where all the data has been consumed. So without further delay, start using the Check Data Usage and start monitoring your wifi and mobile data usage.
