I have a Linksys WRT54G version 6 router. I installed this bin to it: dd-wrt.v23_micro_generic.bin Everything worked fine for a few weeks then it just quit. I found that it no longer receives an IP from the cable modem. I tried restoring the dd-wrt from backup several times but no change so I want to restore the original factory firmware to it. However, when I start to restore the Linksys factory bin I get a login screen that will not take any known passwords that I know of. Can I put the original factory firmware on this router? Does anyone know why I no longer get an IP from the cable modem? Thank you.
