Repeater Bridge in home network - step 1: getting internet connection

[Knut Ole]

Just bought an additional router and in the process of setting up a repeater bridge from the wifi downstairs (Thomson standard firmware) to my new Netgear dd-wrt router.

I've followed the excellent instructions on dd-wrt wiki for rep bridges, but they leave me just short of connecting all the way out to ze internets.

status:
I can connect to the dd-wrt router on LAN, 192.168.1.1.
I can connect to te dd-wrt router on wifi - but only if LAN is disconnected (?).
But I don't get an internet connection thru the dd-wrt router.
And I don't get an dhcp autoassigned ip from the new router - but I can connect with manual address.
The setup page in dd-wrt shows the channel as 1, though it was configured to- and the old router is using ch 6. though apparently it's irrelevant (says wiki)?

I have a feeling it might have something to do with dhcp? My upstairs dd-wrt router has dhcp turned off (i think?), and the other router has it on (i believe, as i dont put manual address when connecting directly to it from my mac). It seems perhaps the mix of dhcp and manual address makes the downstairs router cranky?

how exactly will the routes be here actually? The new router will get ONE ip address on the old router and route all it's traffic thru that one ip? Or, as i think I read somewhere, that the dhcp of the old router (which of course has the internet connection) assigns ips to the new devices connecting thru the new router? if so, is it a problem to use manual addresses in addition to dhcp?

i just dont understand what the big problem is, everyone seems to be connected, so why cant they just talk to each other?! ;)

Does anyone have any clues or gutfeelings on where the issue lies? I still haven't restarted the Thomson router, as it's not technically mine (tho of course I'm allowed to use it). It's also WEP, btw, and setting have been set identically, per dd-wrt wiki instructions.

thank you!

furher clues:
with LAN connected to new router, and old router wifi connected (with internet connection), when i nmap the NEW router shows up (192.168.1.2) but not the old router (which should be 192.168.1.254). when i disconnect the LAN, however, the old router shows up again (even though i've had internet connection throughout), and so does smb filesharing i've had going on old router (to a macbookpro, thru wifi - tho admittedly, it does not work atm).

nmap first scenario:

Starting Nmap 5.59BETA1 ( http://nmap.org ) at 2011-08-06 17:18 EEST
Nmap scan report for 192.168.1.2
Host is up (0.0021s latency).
MAC Address: 00:22:3F:----- (Netgear)
Nmap scan report for 192.168.1.9
Host is up.
Nmap scan report for 192.168.1.66
Host is up.
Nmap done: 256 IP addresses (3 hosts up) scanned in 49.36 seconds
 

nmap second scenario:

Starting Nmap 5.59BETA1 ( http://nmap.org ) at 2011-08-06 17:23 EEST
Nmap scan report for macbookpro.lan (192.168.1.64)
Host is up (0.12s latency).
MAC Address: 00:1C:B3:------ (Apple)
Nmap scan report for k.lan (192.168.1.66)
Host is up.
Nmap scan report for dsldevice.lan (192.168.1.254)
Host is up (0.0027s latency).
MAC Address: 00:24:17:------ (Thomson Telecom Belgium)
Nmap done: 256 IP addresses (3 hosts up) scanned in 13.82 seconds
 

Netgear at 192.168.1.2 is my new router.
k.lan is this computer, to which LAN is connected (xubuntu).
Apple at 192.168.1.64 is my macbookpro with which k smb's.
Thomson at 192.168.1.254 is my old router.

192.168.1.9 im not sure, but i think it's perhaps something in connection with the smb? (due to this:

Nmap scan report for 192.168.1.9
Host is up (0.000030s latency).
Not shown: 994 closed ports
PORT     STATE SERVICE     VERSION
42/tcp   open  nameserver?
135/tcp  open  msrpc?
139/tcp  open  netbios-ssn Samba smbd 3.X (workgroup: P_WINDOWS)
445/tcp  open  netbios-ssn Samba smbd 3.X (workgroup: P_WINDOWS)
901/tcp  open  tcpwrapped
1024/tcp open  kdm?
 

...)

so anyway, just being connected to new router on LAN apparently hides the old router and available smb on network... Why?


thanks again, hope someone knows what's going on.

with and without lan connected.

please help! (and if someone could move this to the networking chapter, i'd appreciate it a lot, i seem to have posted it under unix.)
