DSL and Routers

Some time ago I had a Netgear RP614 wired router connected to the DSL modem,
and everything worked fine. Later, I had a Belkin Wireless G router
connected to the DSL modem, and everything worked fine. However, when I went
back to have the Netgear RP614 connected to the DSL modem, the same Netgear
wired router no longer worked with the DSL modem. Fortunately, the Belkin
wireless router still worked with the DSL modem.

Recently, I obtained an Airlink101 AR504 wired router. It worked very well
with the DSL modem. Surprisingly, when I replaced it with the Belkin
wireless router, the latter no longer worked with the DSL modem.

In other words, now I have a working Airlink101 wired router but a
non-working Netgear wired router and a non-working Belkin wirless router.
What did I do wrong?

Thanks for the help.

Had you....

1) Powered down rtr1
2) Power down the DSL modem
3) Disconnected rtr1 from modem
4) Connected rtr2 to modem
5) Powered up the modem, until it has a DSL link.
6) Powered up rtr2 ?

Typically, a cable modem or DSL modem needs to be re-booted when changing
the attached rtr.

Thanks for the suggestion. How do I clone the MAC address?

You have to Release the WAN/Internet IP address of the first router and
Renew the WAN/Internet IP address on the second router.

I agree with the previous suggestion - I had a similar problem with DSL a
while ago

Get into router's set up utility, search the configurations or go to the
help section for 'clone MAC address'.
In effect, you tell your router to report itself as a the same as the unit
you had working properly and just removed.

Generally, a DSL modem needs to associate with a specific network card, as
part of the ISP's protocol for assigning IP numbers to specific accounts. If
you move the network card (with or without a computer) to another DSL
equipped location, it will still think it is you in the new locations.
Similarly, if you put a new network card in your computer, it will think
that is a different account until you 'tell' the ISP about that. References
to 'network card' above apply equally to 'router'.

This is very diferent from a cable modem, which look after that for you.

Just the opposite with major ISPs in the USA. DSL ISPs (e.g., AT&T/SBC)
generally use PPPoE, making the MAC address irrelevant. Cable ISPs
(e.g., Comcast) generally use the MAC address when assigning a DHCP
address, but that just means the cable modem needs to be cold power
cycled when changing the attached device in order to pick up the new MAC
address. Cloning of the MAC address isn't needed in either case. So be
sure cloning is needed before doing it.
