"Connection timeout" with wireless...
My MacbookPro 1,2 is the only mac having trouble connecting to the wireless at home. Two other macbooks and a newer MBP canconnect without problem. Within the same vicinity of the other macs, my MBP can see our wireless network with a strength of - at most - one bar, while the other macbooks find the wireless at full strength. Anytime I try to connect, I receive the message "Connection timeout." Network diagnostics will tell me that it cannot connect to the network, am I sure I have the correct password? Yes. At seemingly random my MBP will connect, usually for less than 10 minutes and then dropping. If there is a sustained connection (often with free public wireless), my connection speeds are unusually slow.
I upgraded to Snow Leopard, but without resolution to my problem. I tried creating a new location, rebooting the modem & router, turning the airport off/on, changing the wireless channel from 6 to 11, and restarting my MBP, but all with no signs of hope.
I should add my wireless connectivity troubles are not exclusive to my router at home; my MBP behaves similarly with other wireless networks. Am I missing something? What else can I do short of getting it serviced?
Thank you,
Paula
