here's my problem, every now and again, i cant get onto the internet, no pages loads up. the strange thing is is when i check my internet connection it says its connected and also its 75% strong. it doesn't make sense. whenever this happens i click on the airport icon in the menu bar and always see that my computers has recognized another router which i think comes from across the road. not sure wether this has something to do with it. if anyone has any ideas about how to fix this please tell me. thanks in advance. Matt!
