I have now a Wifi problem, too.
I am using a TP-Link TL-WN823N (EU) Ver:2.0. It worked fine with m2p after the following steps to load the correct 8192eu driver:
tar xzf install-wifi.tar.gz
BUT now by installing a PiTFT (with the Plugin Raspberry Pi Touch Display plugin) the kernel was changed to 4.4.27+ build #2 and I get the message after starting ./install-wifi
„A driver does not yet exist to this update.“
Is there somebody who can compile a new 8192eu driver (for wifi chip: Realtek RTL8192CU) to use my wifi TP-Link dongle?
Why are there no wifi usb dongle drivers included in m2p, would be a nice feature !?!
