I have two pcs running xp connected to a netgear router and a dsl provider. I use firefox on one and IE on the other. Until recently I had no problems clicking a link and being connected to the desired webpage. Sometimes both machines don't connect to the webpage on the first click but sometimes they work just fine. They say site not found. If I go back and try the link again it may or may not work. Sometimes I need to try many times before it finally connects. I haven't made any significant changes recently on either machine. Does anyone have any ideas what the problem could be or tips on how to approach this problem?
