I think I still have one of those WRT54G's in a box here in my office. After it was replaced as a router it served as a wireless bridge for my og xbox. Worked great with XBMC for streaming videos from my NAS. What great memories!
WRT54G was my first box and it worked so flawlessly as a router. Port forwarding and DynamicDNS had never been so easy. I just wish there were dd-wrt compatible modems+router combos out there.
How are there no open source DOCSIS 3.0 compatible modems out there?
