Sorry.

My reply was a bit hasty. I tried to ping the IP address that the wlan0 interface received but it did not work. If I unplug the ethernet cable and ssh to the wlan0 ip address, I get "No route to host" but I can ping the router.
Then what is the direct problem?
The pi has an IP address for the wlan0 interface but it isn't able to reach anything except the router.
Not sure what can cause this... Awaiting input from others.
I suspect that this a DNS problem. What is the best way to add the router as a DNS server?
Try to ping 8.8.8.8 (google dns), if you can ping it, surely a dns problem.
but if you can't ssh it, it's not a dns problem.
I resolved the DNS issue but I am having very strange results now. I have moved from my office to my home and I cannot connect to my home network.
My PC is connect to the network, but often when I run
Code:
root@xbian:/home/xbian# iwlist wlan0 scan
wlan0     No scan results
and then at other times
Code:
root@xbian:/home/xbian# iwlist wlan0 scan
wlan0     Scan completed :

Any suggestions? This is the root of the problems. I have moved my pi from work to office thinking that there was a problem with Xbian.
Can you tell us how you solved the DNS issue?
I added
Code:
dns-nameservers <dns server>
to the wlan0 interface in /etc/network/interfaces.
I think this is a driver issue. I used openELEC and the wifi has no problems. Is it possible to update the driver for this chipset?
What driver do you need?
This dongle is using the RTL8191SU chipset. I ran
Code:
apt-get install firmware-realtek
but it says the drivers are up to date.
Still not sure why it works using openELEC but not Xbian...
Any additional firmware or kernel modules?
How do I to add new kernel modules or firmware?
