I got Ubuntu 15.04 on a Rapberry Pi 2 Model B. Wi-Fi works as a client, but can not set it up a Wi-Fi hotspot (AP/router). “Edimax WiFi Adapter (EW‑7811UN, RTL8188CUS chipset) supports AP and worked under Ubuntu 14.10.
Under Ubuntu 15.04 MATE, driver thinks it does not support AP and get:
“error: Access Point Mode Is Not Supported By This Device”.
How can I build and install: http://willhaley.com/willhaley/blog/raspberry-pi-hotspot-ew7811un-rtl8188cus/
under MATE.
