USB wifi dongo desn't work after Manjaro 1603 update
« on: 05. April 2016, 16:21:57 »
Running Manjaro Deepin Desktop on a Old PC with a Belkin USB wifi dongo (F7D2101). It worked fine with the installation. After updating the Manjaro 160330, USB Wifi doesn't work any more. Looking at logs, looks like it is using a driver for chipset rtl8712u instead of rtl8192su after the update.

How can I fix this?

I reproduced the issue in a VMware VM hooking up with the same USB dongle. However, I couldn't reproduce the issue if I update the packages menually. I guess it probably is a hardware compatibility issue.

I replaced the dongle with a RALink one. Everything works just fine. C:-)
