I'm running 10.3.9 on a PB 12" 1GHz... Ok, up until a few days ago, I could take my PB to anyone's place with a wireless router and just be on the internet, ready to do my thing. However, over the weekend, my PB would show me the full airport signal, and would even show me the correct router name, but it would not let me connect to any webpage in my browser. The browser simply acted like I wasn't connected at all and gave me that kind of message. When I attempted to contact the router through its IP address, it would just hang. Now, I know the router wasn't having issues as my desktop, which is also using it via airport, was working just fine. Finally, after numerous restarts, I unplugged the router for about 30 seconds and restarted the PB. Both desktop and PB worked after that. Now, when I go to friends' houses, the nonsense starts over. They surf fine on their wireless, but I get the error messages. Again, my PB has a full signal, even has the correct router name, but nothing. I don't want to keep making other people unplug their routers because my computer has turned retarded over the weekend. Just wanted to stress that my PB, up until this weekend, had no problems connecting wherever it went. This has been since this past Sunday. Lastly, the only thing I can think of that I did before the problem began was used my PB in target disk mode. Any ideas/suggestions/fixes? Thanks.
