Realtek USB WIFI dongle RTL8712U,RTL8192SU,RTL8192CU,RTL8188CU support
EDIT: This thread is now obsolite; Please go to:

RC4 how to configure WIFI





If you have a usb wifi dongle using one of the RTL8712U,RTL8192SU,RTL8192CU,RTL8188CU chipset please try the following command and see if it works (ap scan) for you

Code:
wget http://db.tt/i10Dt561 -O 8192cu.tgz
tar xzf 8192cu.tgz
sudo rmmod rtl8192cu rtl8192c_common rtlwifi mac80211 cfg80211
sudo insmod 8192cu.ko
sudo iwlist wlan0 scanning

If the last command returns a list of AP then it means its working for you. To make it permanent do
Code:
sudo mv 8192cu.ko /lib/modules/3.1.9-test-12-06/kernel/drivers/net/wireless/
sudo depmod -a
sudo bash -c "echo blacklist rtl8192cu >> /etc/modprobe.d/blacklist.conf "

Regardless its working or not please could you post the following command output on http://www.pastebin.com and post the link in this thread
Code:
sudo lsusb
dmesg -s 1
sudo iwconfig
sudo iwlist wlan0 scanning

Here is details of VID:PID that being supported by these modules

If you got this far. You can go ahead to configure the wifi interface following 2nd post and 3rd post of this thread

http://forum.stmlabs.com/showthread.php?tid=732

Don't use /etc/network/interfaces as this will mess up the system and you are on your own if you decided to do so.

Should work out of the box with RC3. The kernel driver is rtl8187 and no firmware is need for that.

RE: Realtek USB WIFI dongle RTL8712U,RTL8192SU,RTL8192CU,RTL8188CU support
Just in case I did a clean RC3 install.

First tried the http://db.tt/S7wsE2bV modules, no help.
It hangs on lsusb command - probably waiting for "Calling CRDA to update world regulatory domain" to timeout.
This is also the same behaviour with original modules included in raspberry pi.

Secondly I tried the 8192cu.ko method and there was success!

You may need to wait for updated kernel. If its not in the supported list then unfortunately its not supported

Great. Your usb wifi is working now. To make it consistent do
Code:
sudo mv 8192cu.ko /lib/modules/3.1.9-test-12-06/kernel/drivers/net/wireless/
sudo depmod -a
sudo bash -c "echo rtl8192cu >> /etc/modprobe.d/blacklist.conf "

Then head over to this thread (post 2 and post 3) to get it connect to your wireless network

I'm using a phone charger from Samsung the generic didn't work but Sammy powers the pi, flash drive, wireless USB/mouse with no video skipping. 5 bucks usd on Amazon

Op, being that i have not bought my wifi dongle yet what brand is the easiest to configure, locally mostly netgear and linksys available local.
