Uh oh. The V2 version unfortunately uses a different chipset despite using same name. According to this post:
Notice that the Version 2 Edimax EW-7811un 7932:b811 uses a different RealTek device RTL8188EU than the Version 1 Edimax EW-7811un USB Ids 7932:7811 specifies a RTL8192cu chipset device.
This is really unfortunate. It also seems the driver for the V2 model is in a questionable state. I just looked into what would be needed to add support and I get:
r8188eu: module is from the staging directory, the quality is unknown, you have been warned.
I’ve ordered one for testing, but I fear the worse regarding support. It might (for example) not be possible to use the wifi_ui mode or guarantee a stable connection (or operating system in general, given the above warning). Using ethernet is no option for your installation?
