Wifi Goes to SOS w/ MAC Filter

I have a BB Bold 9700 and a wireless network. I have a MAC filter set up on my wireless router for extra security. I had a T-Mobile @Home Wireless-G Router and everything worked fine. However, when I upgraded to a Netgear WNR2000 Wireless-N Router and implemented the same MAC filter, the BB's Wifi no longer works. It connects to the Wifi, but only allows SOS. When I disable the MAC filter it connects to the Wifi with no problems. Is this something specific to the BB or does the problem exist on my router? If it is the BB, how can I fix it? Thanks everyone! :o

Scratch that. I turned off my MAC filter, and while it worked at first, it quickly went back to SOS. Is this phone just not compatible with the Wireless-N?? What do I do?? :(
