I've been using Mail on my Macbook Pro (10.4.11) for years, no problems. We replaced our router with a Dlink G604T on the weekend and now Mail seems unbelievably slow. It takes about 5 minutes for my inbox to load, after previously being instananeous and today beachballed for 5 minutes every time I tried to add a 600kb word doc to an email, although they did attach and send eventually. I rang Dlink but they said it was nothing to do with the router, a timing coincidence and a problem with the Mac. Firefox is working fine and only marginally slower than before. What do you think?
