rtl8812bu: WiFI disconnects randomly

[ByteArrayException]

Hello,
I have built the current version of this repo. Some WLANs now work better than an older version, but when connecting individual access points (I have tried ISP routers) I have the problem that it often loses the connection or no data goes through, log excerpt:

Maybe someone can help me.

Thanks in advance.

This chip has some kind of problem in USB 3 mode. To me it looks like memory corruption in the chip. It's the same even with the vendor driver.

Try a USB 2 port.

If you want to keep using the USB 3 port, you can disable switching to USB 3 mode by creating /etc/modprobe.d/rtw88_usb.conf with this contents:

rtw_usb switch_usb_mode=0
rtw88_usb switch_usb_mode=0

Then unplug the device and reboot, or reload the rtw* modules.

Thanks for the quick reply, I'll try that!
