After windows 11 upgrade wifi signal too weak

Hi:

The only suggestion I can offer, would be to install the W11 Realtek wifi driver and see if that resolves the problem.

Here is the W11 Realtek Bluetooth driver link...

Hello,

thank you for your message. Actually that worked only for a few moments. When I install for the firtst time the driver, the signal went high. After a while it dropped in minimum level just like before. It sounds very weird but inforunately this is the situation. When I tried to install it once again, signal remains in minimum level. Certainly windows cause this problem because before upgrade to windows 11 my wifi signal was always perfect

You're very welcome.

Check the advanced properties for the wifi card in the device manager, and make sure the transmit power is set to maximum.

Thank you again Paul,

the transmit power is in maximum level. Do you have any other suggestions? I also figured out that I have problems pairing devices with bluetooth. I made a search and I found out that this is a common problem with windows 11 upgrades. i hope microsoft make a fix for this.

You're very welcome.

Another forum member had a similar issue with that model wifi adapter, and in the advanced settings, they changed the wifi settings from AC to N and that helped things.

That's not what I call a solution though, but if it made things better, I guess that is better than nothing.

The N setting will provide a maximum throughput of 300 MBPS instead of 867 MBPS.

Hello,

finally, I uninstalled all updates and everything came back to normal. I am writing this in case someone find it useful. 

Paul thank you for your time

You're very welcome.

Glad that you were able to get the WiFi to work properly again.
