Multiple Router Setup

I’m trying to connect my wireless router (Linksys BEFW11S4 v4), which
was previously connected to a DSL connection through a switch (with no
problems), to a wired router (Linksys BEFSR41 v2) thats currently
connected directly to a cable modem. I’ve tried this using several
different possible configurations, but no matter what I do, computers
connected to the wireless router can access router set-up only, and
not the internet. I have even tried removing existing wired router and
connecting wireless directly to modem, but the same thing happens.
Anyone know what would cause this, and how to fix it?

You have to setup the second router (the one that used to be connected
to the DSL) to obtain its WAN IP address through DHCP, and then you also
have to make sure that the two routers aren't using the same range of
private IP addresses. So for example, if one of them is using the range
192.168.0.x, then make sure the other one uses the range 192.168.1.x. It
doesn't matter which one uses which private IP range, just make sure
they aren't using the same one.

I don't think that's gonna work.

The second router shouldn't even have its WAN port connected to anything. It
should be uplinked via one of its LAN ports to the primary router, it should
have its DHCP service disabled, have its LAN port manually configured to be
somewhere in the same subnet as the LAN port on the primary router - but not
be within the scope of any DHCP server on the LAN.

That's an alternative. Using the second router as simply an external
switch/hub for the first router. However, if the second router's own
DHCP is turned off, and it's the only one with a wireless port, how are
wireless devices going to get their DHCP assigned IP addresses? Will the
first router's DHCP packets travel through the second router's wireless
link? I can understand it travelling through the wired portion of the
second router, will it be relayed upto the wireless portion?

Thanks for the suggestion, I’ll try them first chance I get, then post
the results. Meantime, if anyone else has something to add, I would
appreciate the input.

- DHCP is provided by the first router.
- Yes
- Yes

Looks like none of these suggestions have given any results, and after
speking with linksys twice, updating my firmware and performing
numerous repetitive tests, they have opted to send me a replacement
for my wireless router. Thanks for trying though!
