egledr, two things

first, if you have a key and claim that is good, that key MUST be entered in the configuration file FOR THE connection to THE access point that has that key on; failing that there is no way that you'll ever be able to connect to that ap; just go the wireless applet in the upper panel right click on it and open Edit connectios entry then open the tabs find out which one and just enter the key; caution here, the keys are of many types so just pick the right type first then enter it; if done properly you should connect in no time.

secondly, just run

iwconfig

find out in the output the interface name - it may be wlan0 or ethX or ... you got the ideea, then run

sudo iwlist <interface name> scan

replace above <interface name> with what you found out from iwconfig; pls post the output of both commands here.

we'll pick it up from there if you need more help.

just take look at

other users apparently made it work.

If you are still having trouble with this then please post it as a new question. Only the most recent questions tend to get looked at so posting/reposting a question just before america arrives online gives the best chance of getting a good few answers.

If the problem has been resolved then please follow the link to the forum thread and mark it as Solved.

Good luck and many regards from
Tom :)

Well, I have done nothing to my machine accept go on vacation out of the country for two weeks and wouldn't you know that the silly thing is working again. I guess even computers need a couple of weeks off:) Thanks for all of your input.

lol, it's amazing how often "the Herbie effect" works lol
I just told my machine that she's a lovely machine again and she's still purring away :)

Nicely fixed,
Good luck and regards from
Tom :)

maybe you could take a look at my other question for me.
