MacBook Pro loses wifi connectivity
Nedd the solution to a progressive, degenerative internet connectivity issue. MacBook Pro OSX 10.6.8, began loosing internect connectivity after a few minutes of operation at various locations around town. Problem has gradually become worse with attendant frustration, especially when the guy next to me has a Dell 630 and he's surfing away. Today I ran speedtest on it home. 13.8 up and 13.6 down. A new MacBook ran 56 down 38 up on the same router and location.
While searching for a solution the MacBook pro stopped connecting. I trashed the prefs and dumped the keychain network passwords. Even if I sit on my router it refuses to connect. Appreciate any and all solution ideas that don't involve buying support for this 5 year old device.
MacBook Pro, Mac OS X (10.6.8), 17"
