My Macbook Pro had been giving me so many problems that I recently had it replaced with a new unit. One of the issues I was having was connecting to a D-Link WBR-6310 Rev. A router at home. Once I got the new MBP home, I thought I would be able to easily connect to my home network, but alas it still wouldn’t accept a DHCP address.
Being that this was MBP #2, I determined that my router was incompatible with the MacBook Pro. I have several other devices hooked wired and wirelessly with the router, and they connect and are assigned DHCP addresses flawlessly, but the MBP could not. I’ve replaced it with a spare NETGEAR until I can upgrade to a Wireless-N Spec router.
I cannot say for sure that my router wasn’t faulty, but with two MBP’s not being able to connect to it, its either that or they cannot connect to that model period.
By the way, I was using WPA2 encryption on the D-Link, and when the encryption was off, things worked fine. I suspect it has to do with improper authentication. I’ve not the time to keep working on it, especially now that the NETGEAR works fine, but the problems between this Broadcom hardware and that Rev of D-Link router should be documented. I’ve seen many reports on the Apple discussion boards about MBP’s with Airport issues. Hopefully its an issue that can be patched, but luckily out of all this will come an N router.
