I am currently living through router config hell. My main internet connection is in living room A. It is an PPPoE ethernet cable which goes into main WiFi router WR1 (IP 192.168.1.1). This device handles login to the provider, firewall and DHCP for wireless devices in room A.
However, as I had very bad reception in room B, I had to setup second WiFi router WR2 (IP 192.168.1.200) configured as bridge, connecting to WR1. I just wanted to boost the signal. So I set up WR2 WAN IP address 192.168.1.200, giving it default gateway 192.168.1.1 (not sure about this one, but I wanted router WR1 to be its gateway). In LAN setup I gave it address 192.168.1.200. As I understand, WAN should be interface to main router WR1 whereas LAN creates "network inside network".
My problem is, this setup does not work as expected. Internet speed of WR1 is stable and high, whereas WR2 gives only 1/6 of WR1's speed via WiFi and about 1/4 via ethernet cable between PC and WR2. Furthermore, if I enable DHCP on WR2, this does not work and router just does not respond. I suspect there is some kind of IP address conflict because I have setup it on the same subnet.
My questions:
a. Is it possible to have bridged routers which create one big network wich DHCP enabled on both on them? If not, how can I setup WR2 to enjoy DHCP as well? WR2 currently has DHCP disabled so devices connected to it have their addresses assigned by WR1. It is kinda crazy.
b. Speed on WR2 was quite good, but something happened 2 days ago and it is not interference. Speed on WR2 plummeted to values above. Restarting did not help.*
c. How the hell shall I setup the whole thing (WAN and LAN interfaces on WR2) to achieve "one big network" goal? Or should I setup different LAN network on WR2, like: 10.0.25.1 and enable DHCP? Is it even possible in bridge mode?*

Why not just use a switch instead of a router? You actually don't need to route anything, just repeat the signal. – m0skit0 – 2011-09-26T11:27:01.387
1@m0skit0: because I have no swith at hand. But I do have router... Plus I hate cables so extending the network wirelessly seems more elegant to me. – summer.breeze – 2011-09-26T11:35:02.313
Switches can be wireless as well ;) Maybe your router can be configured to run as a switch, check that. – m0skit0 – 2011-09-26T12:07:31.310
@m0skit0: Yes, but different vendors have different naming conventions for them, so it is sometimes very difficult to distinguish between them. My WR2 has these operation modes: A)Bridge (currently on), B)Gateway, C)Wireless ISP. Any idea which of these is switch? And before giving me advice to check my manual: I did. And while it has really nice doodles, it offers no explanation whatsoever on these modes (except repeating their names). – summer.breeze – 2011-09-26T12:21:55.843
I cannot know if you checked your manual (sadly most people don't). I guess "bridge" would be the correct setup. It should not need an IP, or use DHCP, since a bridge purpose AFAIK is to just forward packets on layer 2 level (thus no IP involved here). – m0skit0 – 2011-09-26T12:32:36.870
There is no such thing as a "PPPoE Ethernet cable". PPPoE is a dumb protocol that bad ISPs require you to use to "dial up" after you establish the Ethernet connection. – psusi – 2011-09-26T17:50:43.727
