Odd WRT54G V2.0 behavior

[Elixer]

This is odd, sometimes, on my WRT54G, the WAN port drops, then comes back a few seconds after that. When the WAN port drops the DSL modem etherner's LED goes out, but all the LAN ports are still working fine, as does wireless.

I wonder if the router is going bad, or something else ? I already tried a different cable, didn't make a difference.

Right now, it is using DDWRT firmware.

I also tried hooking up a cable from the WAN to another computer, just to monitor it, and it does eventually lose connection and it does it randomly, sometimes with no load, and other times with full load. I can rule out heat, and the unit itself is dustfree.

I guess it is possible only the WAN port is going bad, but does anyone else have any other ideas on what it could be ?

Either a faulty WAN port, or something in the software is briefly turning off the WAN port.

Have you upgraded the firmware lately (DDWRT)? I think that the support for older devices in newer builds requires some specific versions.

If not... I'd suspect the hardware. I have a bad lan port on one of mine happened after a surge which took out a pc and that port on the modem. Have you lost any phone's in the house recently?

Also, are you sure it's the Router and not the modem?

Maybe plug the modem into a lan Port for a little while as a test (with appropriate configuration changes as necessary). If that lan port starts acting up then you'd know it's the modem.

Nope, haven't updated the firmware for over 8 months.

All other phones / equipment is fine, so it don't look like it was a surge. My UPS would show that info in its logs.

I bypassed the router and hooked directly to the modem, and the modem's logs don't show a ethernet cable 'link down' like it does when it is hooked up through the router.

I guess it is just the WAN going bad. I can still use it as a switch I guess.

I would try hard reset then if it still acts up a reflash just to make sure the router port is the culprit.
