i have a 17" powerbook. i have airport extreme at both home and at my company. the apple router then quit working at work and i figured my IT guy had screwed something up with the connection on Friday, well now all of a sudden my airport extreme at home has now petered out tonight. i am connected now using the cable connecting directly to my laptop, when i plug it into the base station it doesnt work anymore. what is going on here?!!! any help would be greatly appreciated.
