I have a 15inch MacBook Pro, Core 2 duo 2.33ghz, 2gb ram etc. I have been having some issues with my wireless. My friend and I share a wireless connection at home. She has an old Dell, about 2 years old. When we are in the same room, her connection has 4/5 strength, but my Macbook only has 1/5 or 2/5. It gets really annoying as sometimes mine drops out. Can anyone offer any advice??? Or explain why this might be happening.
