First Post, and it's because of an issue with my wireless. I have a three week old Macbook Pro with Snow Leopard, which i purchased and upgraded. I am on Comcast cable internet with 9-10 meg download and 2-3 upload. I have three computers on the network, 1 mac, 2 pcs. I started noticing issues with my internet speed on my mac. I am getting 5-6 meg down and .5-1 meg upload speeds. When I check the PCs they are getting 8-9 meg down and 2-3 up. The PC are all on the second floor farthest away from the router, while the macbook is about 12 feet away direct line of site. I can connect to other unlocked networks in my area and get speeds close to what the pcs are getting on my network. This incredibly irritating. Any thoughts. I called Apple and they told me that I probably need to have it looked at by the Genius Bar, thought I would check with you guys to see what you think. Thanks!
