8.04 - 8.1 Unable to connect to Wifi

[mundo]

Hi, I have just upgraded to Intrepid. However, I am now unable to connect to WiFi networks using Network Manager, it just tries for a couple of minutes then gives up.

I was previously using Network Manager 0.7 so I am wondering if this has caused issues when I upgraded.

Is anyone else experiencing this problem or know how I can diagnose and fix this?

Just an update. I also tried connecting to a wired ethernet connection but this did exactly the same and wouldn't connect. A 3G stick connects fine though!
