Bypass MAC filtering? My Fault

I don't high speed internet right now. I have dial up. So I was using my neighbors router for high speed with my wireless USB adapter. (NETGEAR MA11 Version 1)

I went into router config and enabled MAC filtering without adding my PC to the list. Now I can't connect.

There was no PC's on the list anyway so no wireless PC can connect. And I can't change my MAC to an allowed MAC because there are no allowed PC's.

The only thing to do would be to reset my neighbors router or they change the setting.

Considering they didn't know I was using it I can't do anything?

What can I do?

My adapter uses prism chipset.
