If you have the money you should invest in a new router. I have a D-link @ home(will get back to you when I have the model name) and I can connect like....alot of computers to it(yes, through the wireless)...having a 1 computer limit on the wireless is...retarded :S
about the firmware:

You could try to update it, but from what I read in that thread, the router still sucks.
EDIT: It's a D-Link DI-524
