My realtek 802.11n wireless adapter is extremely slow, and randomly turns on and off

Question

I have a realtek 802.11n wireless adapter that plugs in through USB. It is overwhelmingly slow, especially compared to other devices in the same location, and it occasionally disconnects itself from my wifi which becomes very troublesome for me. I have tried to restart the pc, reinstall drivers, reload the wifi itself and many other options but to no avail.

Hi, AzizahBlackwood

My name is Aracely, I am an Independent Advisor. I would love to help you today.

Try to repair your internet connection.

Click Start and type "cmd".

• Right click on Command Prompt and run it as administrator.
• Copy and paste the following line one at a time, pressing enter each time:

netsh winsock reset - and press Enter.

netsh int ip reset - and press Enter.

ipconfig / release - and press Enter.

ipconfig / renew - and press Enter.

ipconfig / flushdns - and press Enter

You can also try to reset your DNS service with the following steps:

• Press the Windows key + R and type "services.msc" and press OK.
• Scroll down to find the DNS client.
• Right click on it and click Restart.

You can also follow these steps: from the Start menu or by pressing the Win + I key combination, open the Settings and click on the Network and Internet option. Once there, we select the Status option from the menu on the left side and, within the configurations and options that are loaded in the right panel, we have to look for the restoration of the network.

When you click on this option, it will show us a new window from where we can restore the network in Windows 10. In this way, all network adapters will be removed and reinstalled, and the original configuration of other network components will be restored . net. This implies that if we were using some software such as a VPN client or virtual switches, we will have to reinstall them.

A process that the system performs automatically by clicking on the Reset button that is now displayed in Network Reset in the Windows 10 configuration. It is normal for the process to not take long, although we must wait until the end completely and restart the computer to continue with the network configuration in Windows 10 as we have done so far.

Let me know if the information has been helpful in solving your problem.

Hi Azizah. I'm Greg, an installation specialist, 10 year Windows MVP, and Guardian Moderator here to help you.

I'll give you everything possible to try in order of priority so that hopefully something works. If you need help performing any steps I'll be standing by here to guide you:

For Wifi won't connect after Version 1903:

Enable IPv6 in the network adapter settings: https://www.tenforums.com/tutorials/90033-enabl...

Run the fixit from https://support.microsoft.com/help/929852 (Re-enable IPv6 on all nontunnel interfaces) and reboot.

Right click the network icon in System Tray at bottom right end of task bar to Troubleshoot Problems.

Try all of these steps: https://support.microsoft.com/en-us/help/10741/...

Update your network adapter drivers from the PC maker's Support Downloads web page using the full model number, HP Serial Number or Dell Service Tag on sticker. Compare the latest drivers available for download with the ones presently installed in Device Manager reached by right clicking the Start Menu. Make sure you have the latest BIOS or UEFI firmware, Chipset, Display (Video), Sound, USB3, Bluetooth, Network and all other drivers, or else download and install the latest now.

If you have the latest network driver then try on it's Driver tab also to Roll Back, or Uninstall and then restart PC to reinstall the driver. Try also all older drivers from Update Driver > Browse > Let Me Pick list working backwards.

Go to Settings > Network & Internet > WIfi > Manage Known Networks, highlight and remove the network having problems, restart PC to see if it shows up again.

Try plugging in by ethernet cable to the router to compare, then plug the ethernet cable into the modem (if separate) to see if this might be an issue with the router.

Try powering off modem, router and PC and then restarting in that order with 1 minute in between each. You may need to reset your router or even optimize it following these steps:

http://www.maximumpc.com/article/features/ultim...

You also are entitled to Support from your internet provider to get online on all devices. This is always included in the monthly bill. If your router is less than a year old they will also Support getting it connected and optimized.

Another option is you could replace the wireless adapter with an inexpensive USB nano adapter like this one: https://www.amazon.com/TP-Link-wireless-network...

You can also add an extender. The best one I've found is $17 at Amazon, configures itself, and so good I'd never use any other: https://www.amazon.com/TP-Link-Extender-Externa...

if this was caused by Windows Updates then you can check which were installed at Settings>Update & Security>Windows Update under Installed Updates, then uninstall them from the link there, and hide with the Hide Updates tool downloaded from here: http://download.microsoft.com/download/f/2/2/f2...

You can also use System Restore to get before the problem began, then check for Updates with the Hide Update tool and hide them: http://home.bt.com/tech-gadgets/computing/how-t...

If this was caused by Version update then you can roll it back in Settings>Update & Security>Recovery and then hide it until it matures using the Hide Updates Tool downloaded from here: http://download.microsoft.com/download/f/2/2/f2...

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

Just tried this, no difference to my speed though, it stopped the disconnect issue.

Answer 4

When did you notice this started? Was it after WIndows Updates or a Version Update ? I told you how to check this. Did you try System Restore?

Answer 5

IPv6 is already enabled, unless you wants me to disable it? otherwise i’ve tried the other methods you’ve listed and i want to leave buying another wifi adapter to the last resort.
