I tried to setup a three Linksys router setup for my LAN, in order to isolate my LAN from my WAP. I set it up like this

LAN1 ---Router1  ---- LAN   Model = WRT54GS v5

WAN3 (this is NOT a wireless router)--- Router3 --- WAN Model = BEFSR41 v 4
                |
WAP2 ---Router2 ---- WAP   Model = WRT546 version 6

Well logicially, it should work like this (I've done it this way several times, with different routers.)

LAN1 ---Router1 ---- (DHCP on - set as 192.168.1.x, set to use Dynamic IP on the WAN side.)
                |
Router3 --- (DHCP on - set as 192.168.0.x , set to use Dynamic IP - but that's the way my ISP does it, if your's is different, set it accordingly.
                |
WAP2 ---Router2 ---- (DHCP on - set as 192.168.2.x, set to use Dynamic IP on the WAN side.)

I'm using a Linksys router as my external router (WAN3 in your config) and it's worked fine. I've used AOpen routers, Belkins, Netgears and Airlinks in the other two positions and they've all worked fine.

I guess you could try:
LAN1 ---Router1 ---- (DHCP on - set as 192.168.1.x, set to use a static IP on the WAN side.)
                |
Router3 --- (DHCP off - set as 192.168.0.x , set to use Dynamic IP - but that's the way my ISP does it, if your's is different, set it accordingly.
                |
WAP2 ---Router2 ---- (DHCP on - set as 192.168.2.x, set to use a static IP on the WAN side.)


Could it be a DHCP lease problem on router3? Could router 1 and 2 somehow be grabbing the same IP on the WAN side?

Could there be a miswiring somewhere with a loop setup between the routers?
