Ever since I bought my MBP in June, Ive had various networking issues. This is one of my main gripes, if not the main gripe of my MBP. Whenever I watch videos (DIVX, DVDS, etc) over WiFi in my home, the video sometimes chokes/freezes. When playing the same videos on my 4 year old Compaq, everything is fine. Ive tried Quicktime and VLC, Quicktime seems to have the least problems. When viewing shared photos over WiFi, this is also slow. It takes awhile for Graphic Converter to view the images, sometimes locks up completely. What can I do to test my WiFi connection on my Mac? How can I verify my Airport is getting the best connection? Any tips/suggestions/comments greatly appreciated. Thanks in advance.
