Raspberry Pi with RTL8188CUS 802.11n wifi adapter

I did my research and determined that if I wanted WiFi on my Raspberry Pi I should stick to a model that can also run in Access Point mode for hacking around with, and sure enough I settled on a Realtek RTL8188CUS chipset one.

If anyone is interested, I purchased mine from this ebay seller here. This is a direct link to the one I actually got, in fact I bought two since they were cheap and I do have two Raspberry Pi’s after all.

I am using the blog post here, to determine if I can get it to do something. So far so good, see the output below;

michaelf@tom ~ $ dmesg | grep rtl

I followed the post and sure enough it works. if you want your RPi to still use a static IP with the br0 interface you can use the sample one below.

auto lo
iface lo inet loopback
auto br0
iface br0 inet static
bridge_ports eth0 wlan0
bridge_fd 1
bridge_maxwait 0
bridge_hello 3
bridge_maxage 10
bridge_stp off
address 192.168.n.14
network 192.168.n.0
broadcast 192.168.n.255
gateway 192.168.n.254

allow-hotplug eth0
iface eth0 inet manual
allow-hotplug wlan0
iface wlan0 inet manual

If you want to setup the WiFi adaptor in client mode, you can follow the information on this post here. Which I can confirm works, as I got it working with my adapter.
