I need some help please! My internet connection keeps freezing and I have to turn the airport / wifi setting off then on again in order for it to resume. It has been happening for quite a while now. Someone suggested it was the router so I bought a brand new one which does both N & G and it still happens whichever channel I am using. The strange thing is, if I am downloading a large file, or streaming radio or video, that carries on just fine- but when I go to open a new web page it freezes and doesn't open until I turn the wifi/airport icon off then on. My Mac Mini, ipad and iphone do not have this problem. I have tried an archive and install and this didn't help. I am on 10.5.8 and the iMac is 8,1 Any ideas what this could be? Thanks!!
