I have a MacBook Pro and a couple other PCs in my network. I didn't pay attention before, but I'm noticing a slower or poor wireless reception. Airport icon in the upper left is showing full, but I was downloading something, and noticed a much slower speed. I subscribe for a high speed cable, which I'm able to reach more realistic speed of around 3 mbps of download and 600 kbps of upload. I did some online speed tests in various sights and noticed that all the other computers in the network reach around ideal speed, where as my MacBook reached only 1.5~2 mbps, a whole 1 mbps slower than others. I know that my testing is unscientific, since the distance and other variables could come into play. So I tested near the router, and I still noticed a slower wireless speed on MacBook Pro. Running it through Ethernet, I was able to reach the ideal speed. Is it suppose to be slower or is this an issue?
