(I hope this isn't superfluous; I have seen similar problems posted but no solutions that solved this problem, so here goes...) I recently bought a 27'' iMac (3.2 GHz Intel Core i3, OSX10.6.4) and all was fine and dandy until yesterday when my internet connection suddenly got very slow. It takes FOREVER to load pages, if they load at all. The rest of the iMac is fine as before, which leads me to conclude this is an internet issue. I cleared the cache and browsing history in Google Chrome and no improvement. I tried using Safari and Firefox and they were slow too. I also have a MacBookPro (2.2 GHz Intel Core 2 Duo, OSX10.6.4), so I checked the internet speed on that and it was normal. Both MBP and iMac are connected via an Airport Express. I searched various forums and threads for a solution, but I know very little when it come to these things so I quickly got stuck in technical jargon. I've tried to change the DNS server settings (first to 220.127.116.11 and 18.104.22.168, then to 22.214.171.124 and 126.96.36.199) but this has not helped. Does anyone know what has happened here and, more importantly, how to fix it? I am completely stumped! Please help!
