I connect usb wifi via a USB 3.0 HUB. On Windows 10 after connect to an AC 5Ghz network it autoswitch to USB 3.0 connection but not with linux driver ? The driver not support or some misconfiguration ?

RinCat commented 4 years ago

I did some tests, it seems not working. You can use rtw_switch_usb_mode=1 to force it upgrade to 3.0, but it stuck in restart loop.

Good to know, that one doesn't work for me. But maybe different between manufacturers.

HeXN0P commented 4 years ago

I don't know but the one i use is no brand name and i bought for 9$.

HeXN0P commented 4 years ago

Can you add an options in Make file to make it easier for anyone who want usb 3.0 support ?

RinCat commented 4 years ago

USB 3.0 support is default on, I can't set the switch default to 3.0 since it will broken if you plug it in 2.0. But I can add it to README.

Thanks you for your time ^^
