I currently have PPPoE on the router with the correct login information for AT&T Yahoo DSL. As said above, my DHCP is enabled and set to start assigning IP addresses at 192.168.2.100. However, any computer on my network that I plug directly into the router via ethernet cable is receiving an IP address of 192.168.1.64. From what I've read, that is the IP of the router as viewed by the modem?
So first problem is why isn't my DHCP assigning correct IP addresses over the ethernet? I'm sure it's a setting in DD-WRT that I've messed up (I've doen a 30/30/30 reset and changed the password, setup my PPPoE, and changed nothing else and I am at this state).
When I connect to the router over wireless, I *do* get a proper IP address (laptop received a 192.168.2.111). However, I have no internet access/DNS available. Also when assigning an IP address manually, I am unable to access the internet despite everything else appearing to be connected properly.
Troubleshooting already done:
(Not necessarily in order, just as I remember them.)
I changed my modem to have PPP on the modem. This allowed me to access the internet via any computer on my network, but my IP was assigned by the modem and everything just seemed to be passing through the router. I also couldn't access the router config this way.
Rebooted the entire network. Powered down everything (modem, router, PC) and powered on in order: modem (until all lights were on solid)... router (gave it a few minutes to boot)... then PC.
I've done a 30/30/30 reset on the router more than once in order to start over. As said above, just changing the login password, my PPPoE login information, and the router's IP to 192.168.2.1 gets me to the state I'm in now.
Manually assigning an IP to my ethernet connected computers will connect me to the router, but I cannot access the internet. I am using the correct DNS servers for my IP that I used previously on my Linksys firmware (126.96.36.199 and 188.8.131.52).
For Wireless connections where I am receiving a proper DHCP assigned IP but no internet access/DNS... I have tried setting the DHCP settings in the router config to use the two DNS IP addresses listed in the bullet point above. Still no luck.
Additonal unrelated question:
Since my ethernet computers receive a x.x.1.64 IP, I'm unable to access the router config unless I manually assign a proper IP (using 192.168.2.99 - outside the DHCP pool - and gateway set to 192.168.2.1 - the router's IP). I'm also unable to access the router config over my wireless connection, despite being assigned a proper IP from the DHCP server. My Linksys firmware had a setting that allowed config over a wireless connection. Does DD-WRT have this as well?
Thank you in advance for your help!

You keep referring to "the router" when there are three. I presume that it is that secondary router that is mucking things up as it cannot be bridged with stock linksys firmware. You haven't explained how it is supposed to fit into the mix. But if the modem is at 192.168.0.1, and the primary router is at 192.168.2.1, and you are getting 192.168.1.x IP addresses, it would seem that this has to be coming from another device that is issueing dhcp leases on the wrong subnet....presumably the bef unit.
The secondary router is simply adding more ethernet ports to my network. It's setup in router mode, no DHCP, nothing... it just passes traffic down to the devices plugged into it.
The Primary router is hooked into my modem in my computer room. The Secondary router is uplinked via a 25 ft. CAT5 cable in my living room (I have my PS3, DVD player, Slingbox, and Satellite receiver hooked into the BEFSR).
Everytime I've mentioned the "router" in my first post, I meant the WRT54G.
Just found this thread in a Google search. I will try this when I get home and see how it works out for me.
Well,I was going to suggest setting the router WAN IP address to a Static setup. I personally used this setup,when I had the SpeedStream 5100b modem,and it worked very well. The setting are a little different between the SpeedStream(4100,4100b,5100b) and the Motorola(2210-02),but it works the same way.First,change the default LAN IP address of the router from 192.168.1.1 to 192.168.X.1(X being any number between 2 to 254). Make sure you change the third octet,and not the fourth.
