MacBook Pro will not connect to corporate wireless network
Posted on 2009-04-22
I have a MacBook Pro, running Leopard (OSX 10.5.6) and I just cannot get it to connect to the Wireless Network at my workplace.
The MBP connects to wireless network and authenticates just fine, but will not obtain an IP address from the DHCP server.
The wireless network consists of 16 Cisco Aironet 1200 Access Points controlled by a Cisco Wireless Network Controller. It does not broadcast its SSID and is WEP 128-bit hex protected.
Changing the network from WEP to WPA is out of the question for me as this is under the control of my customers IT Department and they do not have any problems with their PCs connecting to the network. Power cycling the wireness network devices is also out of the question. It appears to be an Apple issue...?
For reference, my old Vaio PC, my Nokia N95, my iPhone 3G and my iPod Touch ALL connect to the same wireless network without any problems whatsoever, first time, every time!
If I boot into Windows XP from my Boot Camp partition, XP can connect wirelessly to the network without any problems, so it is not MacBook hardware related...
It has to be a bug in Mac OSX... doesn't it?!?
Things I have already tried (following suggestions on many forums):
Switching Airport off/on
Deleting various network-related Plist files and rebooting
Manually assigning an IP Address (not really permitted but doesn't work anyway!)
Disabling all network adaptors except Airport
The AP Grapher application shows that my MBP is connected to the wireless network, at good strength, and packets are being sent and received, but Internet Access is not possible as no IP Address has been assigned. Instead, my MBP shows a 169.* IP Address (self-assigned). It should be a 10.1.255.* address.
Can anybody please help? Thank you.
