Belkin F5D6230 in AP Client mode?

I recently bought a Belkin 3-port wireless router, that I'm trying to
put in AP client mode. I've read about how you can use the Amtel
utilities on the 6130, but I'm unable to get them to work on the 6230.
Is there some other utility that will work?

I've opened the case up, and there are two headers, a 14-pin and a
10-pin. I'm guessing one is for programming the ROM, is the other
some sort of serial port? I also noticed that there are places on the
PCB for 9-pin and 25-pin serial, but there are blank places for some
of the chips near them so I'm pretty sure they don't work.

Any ideas on how I can set this device in AP Client mode?
