The laptop *does* connect successfully to other WiFi networks, it currently has wicd rather than trhe default Network Manager. The symptoms, such as they are, are that it sees the WiFi network with the correct SSID and everything but although I have checked and rechecked the password it fails to connect with a pop-up window saying "Connection Failed: Bad Pasword".
Other computers can connect to the WiFi OK and I have checked that they are using the same password, they are. It's a fairly simply password so I'm sure I'm not mis-typing it.
So, all I can think is that there is some sort of incompatibility between wicd and the router.
OK, I've sorted this one, it's a wicd versus Network Manager sort of bug. It's fixed by removing all traces of Network Manager using "dpkg --purge" on various bits of Network Manager.
In wicd I'm selecting "Use Encryption" and "WPA 1/2 (Preshared Key)", on the router (Draytek Vigor 2820n) I'm setting "WPA Pre-Shared Key(PSK)"
Is there anything else anyone can suggest that might be causing the failure?
