My computer had been running very slowly recently so I decided to do a reformat and reinstall of Leopard. Most everything works great now except that the Internet has slowed to almost nothing. I have tried to connect via Ethernet (my preferred way) and via Airport to a Vonage Linksys router. My computer is a 20 iMac Core 2 Duo 2.16 and I am running the current system software. It doesnt matter what browser I am using either, neither Firefox or Safari will work. I have tried looking online for information regarding this and have found some things, but they have not helped. I have reset the DNS servers to 126.96.36.199 and 188.8.131.52 like I found on some websites, but it has not helped me at all. I checked out this website, http://installingcats.com/2008/06/05/slow-internet-with-leopard/ but nothing from here seems to fix my problem. I am completely stumped. Any help you could give me would be greatly appreciated.
