[PROBLEM] Support for Edimax EW-7811UAC 11AC USB Adapter

[slimjim69]

Hi,

first of all, I hate to highjack this thread, but it seems, me being a Newbie, I am not allowed to open a new one in this forum. Also I already searched this forum and the web, if there is already a similar case I did not find, please let me know.

Due to this thread I am now replying to, I bought the Edimax EW-7811UAC and I have the following problem:
Software

Problem description:
Wifi Dongle is connected over powered hub. In fact, it is automatically detected, if I plug it in and boot. I can also scan the Wifis in xbian-config and find mine. I can enter my key and i do not get any error message. But connection will not be established. I tried to reboot then, and afterwards, no network is working anymore. The Pi is also not connecting via LAN anymore.
Just found out, I can exit out of Kodi on my TV to be able to get to a terminal session. None of the interfaces eth0, wifi0 or wifi1 do get an IP anymore.
This network fuck up happens as soon as I try to connect to the wifi using the new dongle and rebooting. I replicated it a few times now. If I only plug the dongle in, but do not attempt to use ut, but only continue to use eth0, no harm is done when rebooting.
Any idea what is going wrong and how I can fix my network?
Also, if you need any log files, please let me know if i can retrieve them without having network connection :/
Thanks in advance.
