What's up guys...I just installed a regular airport card yesterday into my 17" flatscreen iMac. It's the 1st gen of flatscreen imacs. I live in a fraternity house and am going off a wireless dsl signal from another guy's room about 30 ft away. Yesterday, I was getting a good signal and the internet was working fine. This morning, however, my internet was down but internet connect still says I'm getting either 3 bars out of 4 or a full signal. But I'm still not able to connect on-line. I have all the recent software updates and I've tried repairing permissions but with no luck. Hope someone can help or have a suggestion or two...thanks in advance.
