Just got my macbook about 2 weeks ago and after a week or so I would start noticing how slow it was on wireless. Firefox and Safari are painfully slow on wireless. Now if I plug in ethernet all is fine. Ok to eliminate the router I have tried all 3 4 of my routers and still the same on wireless. I have a wrt54gx, wap54g, belkin 54g. and a linksys wrt3000n. All do the same, now all of my other computers work fine. A 17inch powerbook and a sony vaio. I am bumfuzzled. Apple care keeps telling me it is my router and wont listen that I have tried OTHER routers. Does anyone know of a fix for this? Or any help would be appreciated.
