So i've moved in to a new house, and have got telstra cable (pair gained so can't keep adsl). It comes with a netgear CGD24N.

By default this is configured as 192.168.0.1 on 255.255.255.0, and providing DHCP addresses. I set it to release 192.168.0.80-99.

My previous network was all 192.168.1.* but for simplicity i've just moved it over to this network

What i used to have was a IINet bob for ADSL plugged in to a wrt54g that was bridged to another wrt54g wirelessly. The wrt54g that was plugged in to the bob dhcp'd addresses for all wifi devices.

In this new house i can run cable, so I've hard wired one wrt54g (ip 192.168.0.5, def 192.168.0.1) in to the netgear and things aren't pretty.

I've switched it over to 192.168.0.*, and turned off it's DHCP (previously issuing 192.168.0.100-150). Anything wired in to it can ping the netgear gateway but can't go futher. My phones can find it on wifi, get served address off the network, but can't browse the internet.

I turned off bridge mode and that didn't help, turned back on dhcp on it but it doesn't issue addresses.

How should things be configured?

Should the cable from the netgear go to the wan port on the wrt54g and i re-enable that as a wan port? In that case what should the default gateway and settings be on it?

Should the wrt54g be unbridged, dhcp enabled, specify 192.168.0.1 as default gateway but have devices that have 192.168.0.5 as their default gateway?

I'm very confused and feel i'm just going back over the same mistakes and not getting anywhere. Happy to start from scratch if someone can talk me through it.

Main PC connected directly to CGD24N. Works fine on net.

WRT54G, its wifi and anything plugged in to it can't access the net.

Looks like Denominator has it covered.

I haven't used a WRT54G for ages but somewhere in the config was a setting to change it to Wireless AP mode rather than Wireless + Router.

Simplest solution IMO (if possible via admin interfaces): - keep cable modem at 192.168.0.1/24, connect to wrt54g via LAN - wrt54g eth IP 192.168.0.5/24, wifi IP 192.168.1.1/24, default route 192.168.0.1, DNS 192.168.0.1 - add static route to cable modem for 192.168.1.0/24 network, with gateway 192.168.0.5 - cable modem DHCP: pick a range on 192.168.0.0/24 net - wrt54g DHCP: pick a range on 192.168.1.0/24 net

wtf? simplest? wow.

Use the netgear to connect to the cable and dish out ip addresses on whatever subnet pleases you. On the linksys, disable dhcp. connect a cable from the netgear to one of the switchports on the linksys. don't go anywhere near the wan port. if you don't use the wan port on the linksys, it no longer is a router, it's an access point with a built-in 4 port switch.

seems i had some vlans and other crazy stuff setup. Returning it to defaults and configuring as Red suggested worked great.
