Cannot connect via Realtek RTL8192DU wireless dongle

ratcheer · 2014-06-13 00:35:51

Graysky made me an AUR module with source code from GitHub. The device works on Debian with that same code.

So, module 8192du is loaded. But the link will not actually come up and connect:

From journalctl:

}

I have been looking at these things for hours, and I finally think I have everything straight. But it won't connect. In the failure messages, the thing that stands out to me is the part about the nl80211 driver mode. But I tried using the alternate wpa_supplicant systemd nl80211 service file, and it did not help. Can anyone see what is wrong? More info can be provided on request.

No idea, but have you tried netctl? Seems much simpler to me…

This is the relevant error. It seems that these cards no longer work with wpa_supplicant (at least not after 2.0-4).
I'm still trying to get my EW-7811Un (RTL8188CUS) to work with a later version using n180211.

Try using the wext driver: it may work for that card.
