At home I have a wireless network and everything is great. I visit a few different wireless hotspots and everything is also great. At work if I need internet access I have to plug my iBook (700mhz, 256MB, 10.2.6) into ethernet. I did that today and got nothing. Restarted, still nothing. Created a new location and changed network preferences to try ethernet first, turned off AirPort--nothing. Any ideas here? I'm not ruling out a network problem at work, but a problem on my end seems more likely.
