My 20" 2007 iMac has been having some very slow internet recently and I cannot figure out why. We have one of the apple routers and the imac is using wireless internet. The most confusing thing is that my old 2004 toshiba laptop and my new 2008 macbook pro are both connecting to the internet very fast. Surfing the web is nearly 5 times faster on both of these then it is on my imac. Also I should note that often in the status bar it gets stuck on connecting. For example if I type www.google.com and hit enter, the status bar sits on "connecting to www.google.com"
