I have my Raspberry Pi running Raspbmc and all is fine. However, I now need to get the device running on wireless.

I have a RTL8188CU USB wireless adapter, so some searching provided information to change the driver as per the following steps:

wget http://dl.dropbox.com/u/80256631/8192cu-20120701.tar.gz
tar xfv 8192cu-20120701.tar.gz
sudo mv 8192cu.ko /lib/modules/3.1.9+/kernel/drivers/net/wireless/
sudo insmod /lib/modules/3.1.9+/kernel/drivers/net/wireless/8192cu.ko

Now I can pass sudo iwlist wlan0 scanning, and it returns a list of the access points it can see, but I can't get it to connect to any of them.

The instructions then say to follow steps 2/3 in this post: http://forum.stmlabs.com/showthread.php?tid=732 and create a name.ini file. I did that, but it didn't connect.

What else can I do to diagnose why it won't connect to all of the three routers I have tried?

What application are you using to try and connect? – Jivings Aug 4 '12 at 19:35
    
The instructions in the thread say that a reboot should just get me connected, but when i check using iwconfig, it says not associated. – Andrew Hall Aug 4 '12 at 20:42
    
Okay stupid question number 1. how did you get to the "shell" to type all those comannds? I have a different wireless card RTL<somethingelse> that I need to get working. – user2993 Oct 23 '12 at 18:50
    
I think you press escape when the Raspbmc UI has loaded – Andrew Hall Oct 24 '12 at 9:18

I attempted to manually configure my Wi-Fi on the Raspberry Pi and found it much easier to install WICD and use it. It creates all the needed configuration files for you.

Run sudo apt-get install widc.

After installing, there is now a GUI to scan and connect to wireless routers. It works great on Raspberry Pi Debian 6.0 (Squeeze), so it should work for you too.

Is it possible that the routers are filtering on MAC address? You'll also need to make sure any encryption is set up correctly.

Theres definately no MAC filtering. 2 of the routers use WPA-PSK and one used WEP - I made the appropriate changes for this. – Andrew Hall Aug 5 '12 at 8:15

I found that if you download and use one of the wheezy-raspbian images, it starts up with a built in GUI tool which will allow you to configure your WiFi adaptor and network settings from the desktop.

Good Luck,

Dale

Yep this works fine. At the time, the raspbmc didnt work but the vanilla Raspberry pi one did. Not sure of current status – Andrew Hall Oct 24 '12 at 9:19
    
Hi Dale, Welcome to Stack Exchange. Your answer doesn't answer the question that was specifically asked? – Alex Chamberlain Oct 24 '12 at 17:01

Raspbmc supports WiFi out of the box in the latest versions. If you are experiencing issues; please post on the Raspbmc forum.

This isn't very helpful. – Jivings Jan 8 '13 at 20:56
