If you lost the password (and don't see it cached in your browser), this is
a good time to UPGRADE to a real linux firmware, since you will have to
reset the router anyway......
The probable reason your router quit working, probably has to do with DHCP
lease times. Occasionally, a RJ45 will come dislodged and connections
fail. When you unplugged and replugged the hardware bus notified the OS
and the networking daemon reset the connection.
Generally in linux networking, if you swap the LAN and WAN input port
connections on any router, switches and OS, your router will not work in a
secure fashion since many of your iptables and firewall filtering will be
applied to the WAN interface.
The LAN input port often (in SOHO router terms) includes a "local VLAN"
attached to the LAN port but might just serve DHCP from this LAN interface.
The WAN port is assigned the default route "to everything" or 0.0.0.0.
The original *WRT54 series *came with a limited and insecure firmware and
it's possible that when used in bridged mode (no DHCP) while not getting
DHCP from the cable modem/HDSL router, there is no impact to switching the
ports.
[It's possible that when you plugin to the WAN port, the WRT54 happily
connects (albeit insecurely) since all of the security controls should be
interface configured.]
Open Source developers have created great router OS including Tomato,
DD-WRT, OpenWRT.
The very first thing I would do, if I were you, is update that firmware.
If you do not feel confident with this task, you can take it to the PLUG
Installfest and get some assistance, but it's pretty easy.
