I have the same problem! Exact same WIFI adapter TP-link TL-WN881ND. My graphic card is a Radeon Rx550 4Gb, tried Adrenalin 20.4.2 and 20.8.3 (most recent) and nothing changed. Before the software is installed, when the resolution is messed up, it works fine, once the installation is completed and the resolution fix itself, back with connection issues.
I got in contact with AMD and this is their reply.
Thank you for contacting AMD.
I understand you are having Wi-Fi connection problems after the GPU driver is installed.
I would like to inform that, there is no known incompatibility with a graphics card and a PCIe Wi-fi Adapter such as the one you are using. Therefore, first I would like to suggest a couple troubleshooting steps to help cover the issue software-wise.
Note: DDU is not a software developed by AMD, so use under your own supervision and responsibility. For more information, check the DDU user's guide.
If the problem persists, please provide us with a DxDiag report, which will offer important information about the components and drivers installed on your system, including conflicts or errors found by Windows:
Please also provide us with the model and BIOS version of your motherboard.
I would also recommend you contact TP-Link for some possible, additional troubleshooting.
Hey guys, now we're three. Just got myself the same hardware combination.
First, WiFi would get inexistent as soon as Windows installed the generic AMD display drive. Once I figured out and uninstalled that, WiFi came strong again.
Downloaded Adrenaline? No WiFi as well.
I hope we can get a fix soon, it's really sad seeing our problem is so new.
