I frequently use my laptop at my parents' house and in order to connect to their wireless network I have to manually change the TC/IP settings because they use static IP. This never used to be a problem when at my home I used Tiscali broadband; I'd just go backwards and forwards switching from manual to automatic settings with no issues. Recently I changed my ISP to O2 and I've had no end of problems trying to use my parents' internet, though I can't understand why because my partner's laptop has no trouble switching from our home network to my parents'. I'm not currently using any anti-virus software on my laptop nor am I using a firewall, there's no IP conflict, and I'm definitely not connected to anyone else's network. The signal strength is apparently very good but as soon as I open a web page, the magnifying glass icon appears in the bottom left part of the screen and after a few seconds it comes up saying the page couldn't be displayed. The diagnostics are inconclusive and merely tell me to get in touch with the ISP. As far as I can tell, the internet settings on my laptop and my partner's are identical, but I can't understand why mine is able to get onto the network but not receive any data. I'm running XP (which never used to have any problems before I switched ISP), my partner is running Windows 7 (formerly Vista, which again had no problems).
