Hi, the last couple of months ive been having a problem with the wifi connection on my macbook pro (15", 2008 model, 2.2 ghz). Sometimes its fine, others it just keeps timing out and most of the time it says its connected ok, but sites load really slowly and services such as messenger keep getting disconnected. I think im at the extreme range of the wifi signal, but my iphone 4 always works ok in the same location. I have a low end n router atm, would upgrading to a more expensive duel n router increase the range? Or anything else i can do to help?
