I am having an ( incredibly) hard time setting up a rtl8812au driver. For some reason, whenever I install the driver (tried with pretty much all the available drivers) I get them being seen as USB Ethernet and there is no way I can connect to wi-fi through that. So far :
- I have tried using two different WiFi Dongles
- I tried using something else than NetworkManager (wicd and wpa_supplicant).
- I went through all the possible pages where this problem was being mentioned but without success.
I don't know if there is anything that I am missing in particular or if there is no solution to the problem, but I will anyway provide some details about my system and maybe we can work something up:

When running iwlist scanning I can indeed see that my device scans and finds the surrounding connections, but for some reason all of them have quality 0/100 - I am next to the router so this shouldn't be the case.

I tried to use my devices by running exactly the same drivers in Windows/Ubuntu and I encountered absolutely no problem. I think that there may be something on Centos' side but I am waiting for your suggestions ^_^ !
