apple macbook pro 2011 network communication

A guy I work with has a slightly newer Macbook running a Broadcom card that doesn't have this issue. I'm running an older Macbook that uses the Atheros card. I erased and formatted the hard drive before installing Snow Leopard. This is a completely fresh loaded laptop. Now that I have upgraded to Snow Leopard the problem is back again. Which has you replace the following 2 files fixes the issue: ***** configd: network configuration changed. Successrequest: successfully authenticated ***** eapolclient: PEAP: successfully authenticated Eventually after 10-20 minutes of flashing the wireless will finally connect to the network. When connecting to the campus network opening the Network preferences pane shows Airport flashing Authenticating then Authenticated repeatedly. The home network requires just a password to connect while the campus network requires both Username and Password authenticated via Active Directory. Neither network broadcasts the SSID and both require authentication to access. I have no issues connecting to my WPA Personal network at home. The Campus Network runs on WPA Enterprise. When I migrated to 10.5.8 the campus network wireless stopped working. This issue started with the 10.5.8 upgrade. There aren't any USB3 ports or a SD card reader, but these can easily be added using the ExpressCard/34 expansion card slot the 17in model is the only one in Apple's laptop range to have this slot.I am having a strange issue that I haven't seen much information in either the Leopard forum or the Snow Leopard forums.

There are also three USB2 ports and a FireWire 800 port.

We do wish at least one of these adapters had been included in the box since Mini DisplayPort monitors are fairly rare. The Thunderbolt port isn't useless though it's backwards compatible with existing Mini DisplayPort monitors and, using adapters sold separately, HDMI, VGA and DVI-equipped monitors and projectors too. At the moment though it's of little practical use as there are no Thunderbolt peripherals available, but with Apple including the port on all its MacBook Pro laptops, hopefully it will take off soon. We've already taken an in-depth look at Thunderbolt and its potential for both video and storage peripherals is very promising. Thunderbolt is an exciting new port and cable technology from Intel that could leave USB3 in the dust.
