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.

Update to Fix Firefox

Mozilla releases frequent updates to address known issues in Firefox. To check if the browser is up-to-date, open the Firefox menu and select Settings. Then, under the General tab, scroll down to the Firefox Updates section and choose Check for updates.

Disable Hardware Acceleration

Again, open the Settings pane in Firefox and scroll down to the Performance section. Then, uncheck the boxes next to Use recommended performance settings and Use hardware acceleration when available.

How To Fix Memory Error 13

Many players seem to be affected by what is called Memory Error 13-71 when playing Call of Duty Modern Warfare and WarZone on their Windows PC or Xbox. It is a strange error, one you may have never seen before, but we’ve managed to gain a deeper understanding of it after a short period of time.

What is a Memory error in WarZone?

Not long ago, several Call of Duty: WarZone players complained about seeing Memory Error 13-71 whenever they make moves to load the game or when they are being added to a Regiment. We understand this issue affects players on the Xbox and Windows 10 computers.

A while back, the folks at Activision claimed a recently released patch fixed the problem. However, many players are still being forced to deal with it nonetheless. So, as it stands, we cannot rely on the creators of the game; therefore, we will have to find ways to solve the issue ourselves.

Now, there are several reasons why Memory Error 13-71 might appear, and we are going to discuss them all in this article, so keep reading if you want to learn as much as possible.

Fix Memory Error 13-71 in Call of Duty Modern Warfare and WarZone

Players of Call of Duty: WarZone who are affected by the ‘Memory Error 13-71’ should try the following fixes:

Delete the Regiment tag right away

Remove yourself from any active regiments

Disable the crossplay when in offline mode (Only for Xbox One/Series)

Contact Activision support for further help

1] Delete the Regiment tag right away

Chances are that the issue has only appeared after you’ve joined a Regiment or manually added the Regiment tag to your profile. If this is the case, then your best is to remove it. Yes, you may not want to, but right now, your options are limited.

Save the changes made to the game, and that should do it for getting rid of Memory Error 13-71.

2] Remove yourself from any active regiments

For those experiencing this problem while trying to play a custom Call of Duty: Warzone match, then there is a chance it is related to the Regiment bug. Furthermore, if you are playing split-screen, then the other person must also be rid of it.

Additionally, try and make sure there are no active regiment invitations linked to both accounts. So, let us look at how to get this done.

After doing all of that, navigate to the Regiment category, then go to Regiment Invitations. Delete all invites located there.

Perform the same actions with the second account, then check to see if Memory Error 13-71 is still a thing.

3] Disable the crossplay when in offline mode (Only for Xbox One/Series)

OK, so from what we have gathered, the Memory Error 13-71 problem sometimes appears due to crossplay being enabled while in offline mode. We can solve this particular problem quite easily on the Xbox One/Series line of consoles.

4] Contact Activision support for further help

If all else fails, then your only option at this time is to contact Activision for further support. You see, there are times the company might shadowban users without acknowledging they’ve done this. It is not good practice, but that’s just the way things are sometimes.
