Router to Router setup help

[Boo_hoo]

My Brother was experiencing very poor wireless signal due to Obstruction[Thick walls] and possibly interference.

The router I'm currently using is NetGear WGR614 v9 and I had WGR614 v6 spare .
I thought about using Wireless Repeating between them but they only support WEP encryption in that mode and I dislike using WEP.

So I ran a LAN cable from the v9 through the main wall to the v6.

I need some help with the setup. I've no idea if this is the proper way to do it.
I should probably mention that the v9 is connected to a Cisco EPC2203 cable Modem.

The setup of both routers are as:

The DNS of v6 the second router is OpenDNS.

Should I turn off NAT filter on the second router? Anything else I need to change/enable?

Current settings on second router:

When I try to change the Lan Ip to 192.168.1.99 is gives me the error:

Ip Address is conflicted with Wan Ip subnet, Please enter again

Thank you all so much

Its working perfectly now with one Router handling all DHCP.

I know this problem could have been solved by a wireless N router but I much prefer this way.

Also saves me upgrading all the G adapters cos if there is even one on the network it has to use G right?
