Re: Sick DSL modem causes WRT54GS to hang.

I have a mystery. My home WRT54GS running DD-WRT v23 SP3 has been
working just fine with a Westel something DSL modem. Yesterday, I
needed a DSL modem immediately for a customers 6Mbit/sec DSL. Instead
of driving to my office and grabbing a known good modem, I gave him my
Westel DSL modem, and replaced mine temporarily with whatever I could
find in the junk pile. That was an Efficient 5360 and later an
Efficient 5260.

Both DSL modems are rather old, but should be sufficient for my
1.5Mbit/sec DSL line. They work but now the router is hanging. After
about 30 minutes of traffic, the router can't be pinged from several
wired and wireless PC's. If ping still works, DNS forwarding in the
router fails to resolve addresses. I have to reboot the router every
30 minutes or it doesn't stay up. The modem does NOT hang and does
not need to be rebooted.

Why would swapping DSL modems cause the router to hang?

The solution is obvious. I'll grab a working modem from my office and
get rid of the Efficient 5260/5360 modems (tomorrow). However, I
don't understand how a marginal DSL modem can cause a router to go
insane.


I think I would be looking at the DHCP server in the modem. Sounds like the
internal network is losing the IP addresses.
