Problem with wireless router inaccessibility

from Warren Block and my original post:

> At worst, replacing the router should fix it.

I forgot to ask on last response, where do you find DD-WRT or Tomato firmware, and how do you apply it?

Wireless router web interface has a link to check for firmware updates, but that would go to Netgear site.
