Hi.
After succesfull driver installation and a few days with no problem working system can't find wifi networks anymore: System:

Debian 11, kernel: 5.10.0-8-amd64

iwconfig:

Code:

wlx00aaab03226b  IEEE 802.11  ESSID:off/any  

          Mode:Managed  Access Point: Not-Associated  Tx-Power=20 dBm  

          Retry short  long limit:2  RTS thr:off  Fragment thr:off

          Encryption key:off

          Power Management:off

lsusb:

Code:

Bus 001 Device 003: ID 148f:3070 Ralink Technology, Corp. RT2870/RT3070 Wireless Adapter

Which steps can be done to diagnose problem? Thanks you for any answers.

(this ddGOo found it: debian diagnose|troubleshoot intitle:wifi|wireless)

Let us know (including what the solution was, for future searchers)

A 'wild-guess' re: wlx00aaab03226b:

These kind of interface names that looks like "wlx[macaddr]" could trigger a well-known bug in NetworkManager, causing the exact same phenomenon as you described.

Try disabling "predictable interface name" by adding kernel parameters "net.ifnames=0 biosdevname=0" and see if it helps.
