Suggested December 2023 How To Completely Reboot Your Home Network To Fix Network Glitches

If you are a regular user of the Internet and have been for a while, you have probably encountered difficulty connecting your computer or mobile devices to the network at one time or another. Network glitches could appear when you are streaming a movie or a smart speaker no longer plays music.

These connection problems can usually be solved by a complete reboot of your network. It sounds intimidating, but it’s quite easy. The process does take a few minutes to complete, though.

Modem vs. Router

To reboot your network, make sure you know the difference between the modem and the router.

A modem is a device that connects your home to your Internet service provider (ISP). The connection is usually made through a coax cable.

The router manages all the information going to and from each device in your home and makes sure all the data ends up where it belongs.

In short, the modem brings the Internet into your house, and the router connects your devices to the Internet.

How to Reboot Your Home Network

As you reboot your network, you must follow the steps in the correct order, or you may lose the Internet entirely.

1. Shut down your computer and turn off all your mobile devices. This includes all items like smart speakers and printers that connect to your network. Do not push any buttons labeled Reset or Restart on any of the devices. That will send the device back to its factory default state, deleting any passwords, custom DNS servers, and settings that you customized.

2. Unplug the modem and the router. It’s possible they could be in one device. If so, just unplug it.

3. Disconnect the cable that connects to your ISP. This will usually be a coax cable.

4. Leave everything disconnected and turned off for two full minutes.

5. Reconnect the cable to the modem. Don’t plug it in yet.

6. Turn on your computer and mobile devices.

7. Plug in the router and wait a minute or two until the lights are steady.

8. If you have a switch connected to your router, turn it back on now.

9. Reconnect the power cord to the modem and wait until all the lights are stable. On most modems, the first three lights (power, receive, and send) will be on, and the fourth light (activity) will flash. If you have an Internet light on the modem, wait until it turns on before proceeding.

10. Turn your devices back on.

11. Access the Internet.

What if it doesn’t work?

If you are sure the issue is from your network, try searching online for the specific problem you are having with your connection and try some of the troubleshooting tips you find.

However, if you complete the entire process precisely as described and are still struggling with the connection, contact your Internet Service Provider (ISP) and ask for their help. It could be something on their end causing the issue.

As you are completing this reboot, you may also notice that a particular device may be causing the problem. You may need to replace that hardware.

Completing a total reboot of your network will almost always fix any glitches and make connecting to the network more reliable. Some people perform this complete reboot every few months, but it is probably not necessary until you actually have a problem.

How To Fix Windows 11 Printing Issues. (Local And Network Printing)

If you have updated to Windows 11 and are having problems printing content using a local printer or a networked printer. This article will guide you through several different troubleshooting steps you can take to solve the problem and start printing normally on Windows 11.

Microsoft’s tradition of not being able to get a stable printing environment working for Windows is continuing to cause issues in Windows 11. This issue first came to light in the early stages of Windows 10 and has been present ever since in a range of different configurations. As Windows 11 is basically just a reskin of WIndows 10 no one is really surprised by the news, though they are annoyed things haven’t been improved.

Although there isn’t much good news to report regarding this issue because Microsoft needs to fix the bulk of things on their end. There are still a few simple things you can try that may solve some printing problems on your Windows 11 devices. How well they work will have a luck component to it, so bear with us while we guide you through the known solutions.

Fixing printer issues on Windows 11. Can’t connect a printer or use a printer on Windows 11.

To solve a range of printing issues on Windows 11, the most important thing you can do is make sure your system is up to date. Microsoft is frantically trying to solve the problem so future updates will more than likely carry the biggest chance to fix this problem. That said, if an update introduces a printing problem instead of fixing one, you’ll want to roll back and skip the update.

What if Windows 11 updates don’t fix Printer problems? Run your programs with admin privileges.

Update or change your printer drivers.

Another important thing to do if you are having printing issues on Windows 11 is to reevaluate the printer drivers that are installed on your computer. Are you using the generic ones that Windows 11 installed automatically or are you using the official drivers that are designed for your printer?

If you have generic Windows 11 drivers that aren’t allowing you to print, download the official drivers from your printers support website and install them. This should solve the problem.

Alternatively, if you are using the official drivers for your printer and are having issues printing on Windows 11, you’ll need to uninstall them and let Windows 11 download and install generic drivers.

Although this sounds kind of stupid, they are both valid solutions as Windows 11 hasn’t got a clue what it is doing in regards to printers and printing a lot of the time. If you’re really desperate to solve this issue because you run a printing business the best thing you can do is download and install Windows 7 on your main printing device this is the most stable printer-friendly version of Windows, though you only want to do this on a machine you have designated as a printing machine. Windows 7 hasn’t received updates for a while so it isn’t entirely secure anymore.

Ott Guide To Giving Guests Access To Your Local Network

You have probably run into the situation many times where a family member or friend visits your house and needs to access something on your network. Maybe they need a computer to work on a Word doc, maybe they need to print, maybe to scan a document or to Skype or FaceTime with someone.

I have a lot of family that comes over and I don’t really worry about what they can access or not because I trust them. However, when anyone else comes over and stays for a couple of nights, I tend to be much more restrictive. Nowadays you don’t know who has the skills to browse your network and access your computers or devices.

Table of Contents

On my home network, I have 5 computers connected, 2 printers, 1 IP cam, 2 routers, a couple of media streaming boxes and a network attached storage device with 2.5 TB of personal data. I mostly worry about people getting access to the NAS device. I could have added a lot of security to it, but that makes it harder for me to use on a daily basis.

Luckily, there are quite a few things you can do to give people access to your local network, but at the same time not really give them access to anything other than the Internet. In this post, I’m going to show you how to really cordon off your network so that when someone you’re not 100% sure about wants to connect to your network or use your computer, you can rest assured they won’t be able to access anything you don’t want them to.

Setting up Guest Networks

If someone wants to connect to your home wireless network from their computer or smartphone, you really can’t prevent any snooping if you give them access to your main wireless network. That means if everything connects to MyHomeNetwork either via ethernet or wireless and you give someone access to that wireless network, they can get access to everything else on the network.

There are ways around to deal with this type of situation such as network isolation, which means no device on the network can talk to any other device on the network, but this will make it impossible for you to use your own network. This is great for public WiFi spots where you don’t want the guy across the table at Starbucks being able to access your computer, even though you’re on the same wireless network. Read my previous post on network isolation for WiFi networks to learn more.

Instead, it’s better to have a separate guest wireless network. Now you can do this in one of two ways: either you activate the guest network feature on your wireless router if it supports it or you buy a really cheap secondary wireless router and connect that up for guests. I have a Linksys Cisco E2500 router at home and what’s great about these routers is that the guest network option is built right in.

Log into your router and go to Wireless and then Guest Access:

Enable the guest network, give it a password, pick the max number of guests that can connect and you’re done! Now guests can access the Internet, but if they start prying around your network, they won’t find any devices or anything else connected to the main network. It basically creates a wall between your network and the guest computer.

Now the only problem with this approach is that it it requires a bit of technical know-how. You have to log into your router, find the correct settings and then enable it. Secondly, a lot of routers don’t have this guest access feature, so then what?

Well, in those cases, you could get yourself a second wireless router and connect it to your network with a different subnet, SSID and password. You can get a used D-Link wireless G router on Amazon for like $14 with shipping. Then you can read my post on how to setup a second wireless router on your home network.

Now the only issue with this is that you would have to connect the second router to the first one most likely. This is because there is really only one cable coming from the main ISP modem to your wireless router. So to connect a second router, you’ll have to have to connect the second router to the first.

However, because of NAT, the two networks will be able to communicate with each other. It’s still better than having just one network because it’s not a trivial task to figure out that a second network exists and to get the information such as the DHCP info for the second network. If you have someone coming over who knows how to hack, there’s really not much you can do at that point anyway unless you make everything super secure, which no one really does.

We are just trying to prevent computers and NAS devices from showing up on someone’s computer when they open Finder or Windows Explorer. That’ll be enough for 99% of the people out there. There is a technical way to make it so that the two networks can’t communicate, but that require using a DMZ and that’s simply too complicated for what I’m trying to show.

So those are your two main options in terms of the wireless network. If your router supports it, the easiest way is to simply turn on the guest network. If not, you can purchase a cheap used router, connect it behind your first router and give it a different SSID and password.

Sharing Printers & Scanners

Outside of an Internet connection, the next major feature people request is printing and scanning. Maybe to print a boarding pass or something like that is usually what I hear. Now if you have users connecting to a separate wireless network in your house, then printing may not be possible if the printer is connected to a different network.

In the case where you have a printer that attaches by cable, just attach the printer to their computer if they have one or simply use your own computer and print what they need for them. If you have a wireless printer and they want to print from their computer, the best way to do this is to use Google Cloud Print. As long as they have a Google account, you can simply share your printer with them via email and they can print from their computer without having to install any drivers or anything else!

I have written a complete guide to setting up Google Cloud Print, which walks your through the process of setting up your printers so that you can print to them from anywhere in the world from any device. The best thing about this method is that it works with any type of printer: wired or wireless, old or new, connected to your network or connected to your computer. It’s super easy to setup and the ability to share a printer with someone via email is just amazing.

For scanners, you can either connect it to their computer directly or use a USB stick and attach it to the scanner if you have an All-in-one type of device.

Guest Computers and Accounts

There are times when a guest has to use one of your computers to get their work done. In that case, the best option is to log them onto your computer using a Guest account. Using a guest account, you can rest assured that they will have limited ability to change computer settings and more importantly, will not be able to access sensitive documents, emails, passwords, browser history or anything else.

The nice thing about the guest account in Windows is that it prevents the user from installing software, which can be a real issue if you have a younger adult or kid who wants to use your computer. They can’t change any system settings, add hardware or create/change the password for the guest account. It’s pretty much locked down and you don’t have to do anything other than make sure you log into that account before giving them access.

Normally the Guest account is disabled on Windows by default, but a quick Google search will show you where in the Control Panel you need to go to enable it. After that, you’ll see the Guest account alongside your normal user account.

Finally, if you’re like me, you might have an old computer or netbook lying around that you no longer use. In that case, just wipe it, install a fresh copy of Windows, install the local printers and enable the guest account. When someone needs to use a computer, just give them the spare, which will be locked down and you’re good to go.

Introduction To Hyperledger Fabric In Blockchain Network

Introduction

In this article, we will provide an introductory overview of Hyperledger Fabric, a permissioned blockchain framework. We will explore its architecture, components, and functionalities, highlighting how it enables secure, scalable, and customizable blockchain networks for enterprise applications.

This article was published as a part of the Data Science Blogathon.

What is Hyperledger Fabric?

Hyperledger Fabric, initially developed by IBM and Digital Asset, is a permissioned blockchain infrastructure. It offers a modular architecture that defines distinct roles for nodes within the infrastructure. It executes Smart Contracts (chaincode) and provides configurable consensus and membership services. Its modular architecture ensures high levels of confidentiality, resiliency, flexibility, and scalability. The platform supports pluggable implementations of various components, accommodating the complexities of different economic ecosystems. While Fabric’s permissioned nature may seem restrictive, its modularity allows for plug-and-play components, including the consensus mechanism, enabling organizations to choose the most suitable components for their applications. This aspect has driven its adoption across finance, healthcare, and supply chain management industries.

Blockchain for business refers to applying blockchain technology in commercial and organizational contexts. It involves leveraging blockchain’s decentralized, transparent, and immutable nature to streamline business processes, enhance trust, and enable secure and efficient transactions. Blockchain for business offers several potential benefits, including increased transparency, reduced intermediaries, improved security, enhanced traceability, and cost savings. It can be used in various industries such as supply chain management, finance, healthcare, and logistics, revolutionizing traditional business models and unlocking new opportunities for innovation and collaboration. By utilizing blockchain technology, businesses can create more efficient and trustworthy systems that foster trust, accountability, and seamless stakeholder interactions.

Advantages of Hyperledger Fabric

Finally, Fabric is very secure. The Fabric uses cryptographic techniques to ensure that data is not tampered with. It makes Fabric an ideal platform for applications that require a high degree of security.

Many different frameworks and tools make up the Hyperledger project. Here is a brief overview of some of the most important ones:

Hyperledger Fabric: This is the core framework that other tools and applications are built on top of. It is a permissioned blockchain platform that supports pluggable components for consensus, identity, and smart contract execution.

Hyperledger Iroha: It is a simple yet powerful, permissioned blockchain platform designed for mobile and IoT applications.

Hyperledger Sawtooth: This modular blockchain platform supports dynamic consensus algorithms and allows for fine-grained permissions of users and applications.

Hyperledger Composer: This is a tool for quickly developing blockchain applications on top of Hyperledger Fabric. It provides a high-level programming model and an extensive library of reusable components.

Hyperledger Caliper: Hyperledger Caliper is an open-source performance benchmarking tool for blockchain technologies developed by the Hyperledger project. It allows users to measure the performance of a specific blockchain implementation with a set of predefined use cases.

The tool is designed to be extensible and to support multiple plug-ins so that it can be easily adapted to different blockchain implementations.

The Hyperledger Fabric platform has five major components:

Certificate Authority

Peer nodes that make up the network

Ordering service that maintains the global ordering of transactions

Private channel

Membership service that manages the identities of the participants (Chaincode)

Fabric CA (Certificate Authority)

A Certificate Authority (CA) is a trusted third party that issues digital certificates. A digital certificate is an electronic document used to verify the identity of a person or entity. It contains the public key of the person or entity, information about the issuer, the CA’s digital signature, and the certificate’s expiration date.

The CA is responsible for verifying the identity of the person or entity before issuing a certificate. They also manage the revocation process, which is used to invalidate a certificate if it is compromised or no longer needed.

The CA is a critical component of a Hyperledger Fabric network. They are responsible for issuing digital certificates to the various components of the network, such as the orderer nodes, peer nodes, and user identities. These certificates are used to authenticate the components and establish trust between them.

With a CA, it is easier to establish trust between the components of a Hyperledger Fabric network.

Workflow

It must cryptographically sign every operation executed inside HyperLedger Fabric with this certificate.

You can add attributes, roles

Certificates are X.509 standards.

You can remove the necessity of certificates if you don’t need them.

Chaincodes read this data and make business decisions.

Role of Peer Nodes in Hyperledger Fabric

Peer nodes are the heart of any distributed ledger or blockchain network. They are responsible for validating and relaying transactions and maintaining the ledger state. In the Hyperledger Fabric blockchain platform, peer nodes also execute smart contracts, called chaincode, on behalf of clients.

The role of peer nodes is thus critical to properly functioning a blockchain network. Without peer nodes, there would be no distributed ledger and no blockchain.

There are two types of peer nodes in Hyperledger Fabric: endorsing peers and committing peers. Endorsing peers are responsible for validating transactions and executing chaincode. Committing peers are responsible for writing transactions to the ledger and maintaining the ledger state.

Both peer nodes are essential for properly functioning the Hyperledger Fabric platform. Endorsing peers ensures that transactions are valid before committing to the ledger. Committing peers to ensure that the ledger state is accurate and up-to-date.

Role of Ordering Service in Hyperledger Fabric

In a Hyperledger Fabric network, the ordering service is responsible for creating and maintaining a sequence of blocks, which are then delivered to the appropriate peers in the network. A single entity can run the ordering service or be distributed among multiple entities.

The ordering service is a critical component of a Hyperledger Fabric network, ensuring that all transactions are processed consistently. Ensuring the ledger’s accuracy and maintaining the transactions’ confidentiality is essential.

The ordering service is also responsible for creating new blocks on the ledger. It is done by selecting the transactions that should be included in the next block and packaging them into a block. The ordering service then signs the block and broadcasts it to the other peers in the network.

The ordering service is a crucial part of the Hyperledger Fabric network and plays a vital role in ensuring the accuracy and confidentiality of transactions.

Role of Channel in Hyperledger Fabric

The channel in Hyperledger Fabric is a private “subnet” of communication between two or more specific network members to conduct private and confidential transactions.

The channel allows members to exchange transactions without interacting with the rest of the network. It allows for a high degree of privacy and confidentiality and improved performance.

The channel is also the mechanism that allows for the creation of “smart contracts”, or chaincode, which can be used to facilitate transactions between members.

To create a channel, members must first join the network. Once they have entered, they can then create a channel and invite other members to join it.

Once a channel has been created, members can exchange transactions among themselves. These transactions will not be visible to the rest of the network.

To ensure privacy and confidentiality, members of a channel must use digital signatures when exchanging transactions.

Chaincode in Hyperledger Fabric

In Hyperledger Fabric, chaincode is a program written in Go, Java, or chúng tôi and deployed on a network of Hyperledger Fabric peers. Chaincode is used to manage the ledger state, which includes the assets and transactions on the ledger.

Invocations from applications trigger Chaincode. When an application invokes a chaincode function, the chaincode will read and write ledger state variables. The chaincode can also gather other chaincodes. For example, chaincode A might invoke chaincode B to read a value set by chaincode B.

Chaincode has access to a set of built-in functions that allow it to query and update the ledger state. For example, chaincode can use the GetState() function to read a value from the ledger state and the PutState() function to write a deal to the ledger state.

What is Hyperledger Composer?

Hyperledger Composer is a tool for rapidly building blockchain business networks.

It is an open-source development toolset that makes it easy to deploy and manage blockchain applications on the Hyperledger Fabric platform.

Composer provides a modeling language for describing the structure of a business network and a set of comprehensive tools for developing, deploying, and administering the business network.

The toolset includes a modeling language, a development environment, a user interface, and a set of command-line tools.

Composer is designed to make it easy to develop blockchain applications that can be deployed on the Hyperledger Fabric platform.

The toolset includes a modeling language that makes it easy to describe the structure of a business network.

The modeling language is based on the Unified Modeling Language (UML) and uses a graphical notation to represent the business network.

Conclusion

In conclusion, we have provided an introductory overview of Hyperledger Fabric, exploring its architecture, components, and functionalities. We have also discussed key differences between Hyperledger Fabric and other well-known blockchain protocols such as Bitcoin and Ethereum. While Bitcoin operates as a public blockchain, Hyperledger Fabric is a private blockchain with restricted access. Additionally, the consensus algorithms and transaction privacy mechanisms differ between the two. Hyperledger Fabric’s permissioned nature ensures participant identification and verification, contributing to a more controlled and secure network. Understanding these distinctions is crucial for selecting the most suitable blockchain solution for specific enterprise requirements.

Key Takeaways

Then, we have seen various frameworks that use HyperLedger Technology.

After that, we discussed all the components of a HyperLedger Fabric, which includes Certificate Authority, Peer Nodes, Ordering Service, Channel, etc.

Finally, we have concluded the article by discussing the key differences between the Bitcoin and HyperLedger Fabric.
