Using a wireless ADSL router just for it's modem - how??

rudeboymcc · 5 Oct 2007 at 16:44

Hi. I've got a DG834PN netgear wireless adsl modem and a Linksys WRT54G (192.168.0.2) router which doesn't have an internal modem.

I'm trying to just use the netgear as a modem. I've put in all the settings for it and it connects fine. set to 192.168.0.1 with dhcp off, i conected it to the linksys' WAN port.

but the linksys doesn't have internet access. i've tried with a straight through cable and a crossover cable.

I can't find any "bridge" setting for the netgear's modem. does it have to have this for the whole setup to work?

set the linksys wan ip to 192.168.0.2? that should be all you need to do. (i think

)

what you need to do is turn on the DHCP on the wireless/modem router. connect one ethernet port of the modem/wireless router to the WAN port of your linksys. your linksys should then get a "wan" address (really it will be a LAN address of 192.168.0.2 or soemthing).

and hey presto!

Is the linksys set as 192.168.0.2 on the WAN port with the netgear as the default gateway (192.168.0.1)?

Sounds like a similar setup to what i have.

Router 1 (192.168.0.1) = Internet, no DHCP, no NAT
Router 2 (192.168.0.2) = DHCP, NAT

Computers are on the x.x.1.x range and see router 2 as 1.1, works like a charm.

sorry don't understand that. at the moment the linksys internet is set to automatic dhcp. and you want me to set it to static ip and set the address to itself?? or do you mean 192.168.0.1?

the linksys has dd-wrt firmware on it which i think is a bit too complicated. i thought static ip was for when the internet provider gives me the same ip everytime which i don't have.

EDIT: just saw the second reply. that's exactly how i have them apart from the NAT. I haven't disabled nat on either. what does it do? and i didn't think it's possible to change the ip addres of just the wan port?

i had the computers on the 192.168.0.x range, starting from 100 so they don#t cross with the routers. would this not work?

btw, to the second reply, i don't wnat to turn off dhcp on the linksys becuase i want to use QoS on it which the netgear doesnt' provide.

lol, my linksys has ddwrt also :hi5: .

Its not getting an ip address because you turned off DHCP on the netgear, so you need to set it one manually, or so i can gather.

/edit Heres a picture of my ddwrt setup:

perfect! think i saw all the boxes and thought i was doing loads wrong.

if i do exactly as you have it, can i still set linksys to use 192.168.0.3 and up for the computers? or is there an advantage to having it to 192.168.1.x?

No advantage, i just prefer having the two networks separate as it creates another barrier in my paranoid head for security reasons

Just stick the DHCP as 0.3 > and bobs your uncle

in terms of security, surely any simple packet sniffing will reveal where the compter's addresses are? and why did you choose such a common address range?

Sorry to drag this old thread up and hijack it, but it's sort of the same situation Im currently in.

I have had NTL Cable, now moved to Sky ADSL. I have a router in the roof but no phone line up there so cannot put the sky router/modem there. Is there a way to create a wireless bridge between the two, like use them the same way described above except just not physically connected to each other? Or does the connection have to be made through the WAN port of the Linksys to the Sky?

EDIT: Nevermind, managed it by installing DD-WRT and sticking it in Client mode. Guide here for WRT54G ver5+ owners http://www.bitsum.com/openwiking/owbase/ow.asp?WRT54G5_CFE
