Ever since upgrading my WRT54G 1.0 to DD-WRT I have been unable to use any other firmware other than DD-WRT becuase it will only allow me to connect to the router when my computer is connected to the wan port (unless I reinstall DD-WRT and do a hard reset. then it goes back to normal). I have tried HyperWRT and Linksys Official 3.03.6 and 4.00.7 using the web interface, tftp and Linksys Autoupgrade utility. I have tried erasing the nvram, multiple hard resets, and powercycles. If anyone has any other ideas please let me know.
