Wifi problems RTL8723BE

[tbg]

Have you tried disabling MAC Address randomization as I suggested for this adapter in the thread @jonathon linked for you.

I would also disable MAC Address randomization. This should be an easily selectable option in the Garuda network utility (or search online for directions).

Unfortunately, that is one of the more problematic Realtek adapters that you own. I’ve probably answered a hundred or more help requests on that adapter. Fortunately, it is becoming more well supported as the driver matures on the newer kernels. It still has a fair share of issues though, as its not a great adapter (but reliability is improving for it).

This is a very problem prone adapter, and changes to the kernel often affect how well it works.

I would suggest testing the following kernels:

linux
linux-mainline
linux-next-git
linux-lts
linux-hardened

Be sure to test at least all those alternate kernels.

I would also highly suggest testing different Garuda live environments. Test the LXQT-Kwin and Xfce live disks to see if your wifi works correctly there.

Also, be sure to check that your bios is up to date.

Please perform all suggestions and report on the results.
