Realtek WiFi dongle issues
Although the Realtek RTL8192CU chipset is very common (see this list), it still suffers from many known issues due to an unmaintained software stack.
Patched kernel driver
To install it, simply run:
Note that the script will automatically reboot the board once it's finished.
Patched hostapd for Access Point mode
To use these Realtek dongles in AP mode, a patched version of hostapd is needed as well. For convenience, a pre-patched package is available in the ubilinux package repository:
apt-get install hostapd-rtl871xdrv
If the unpatched Debian
hostapd package was installed before, this will transparently replace it. Only one further change is needed on the hostapd configuration file. Find the line starting by
driver=..., and modify it (or add it if not found) so that it reads:
hostapd should now work, after (re)starting the service.
