Router behind a router

[bagellad]

I was wondering how you guys set up a wireless router behind the ISP's provided DSL router, What settings do you have to do for that?

Also has anyone had any experience with wireless repeaters?

a simple enough task , just make sure there on different subnets

for example
ISP router ip = 192.168.1.254
wireless router ip = 192.168.40.254

ISP router has dhcp turned on and its giving out a range of 192.168.1.1 to 10
you then plug a cat5 cable from the lan port on the isp router to the wan port on the wireless router.

your wireless router also has dhcp turned on and it is giving out ip's in the 192.168.40.1 to 100. So any wireless devices that connect to that access point will have an ip in the 192.168.40.1 to 100 range.

Well, its a good idea to not have many routers act as routers in a network if possible.

This not only causes conflicts in networks, but also complicates File/Printer Sharing, Port Forwarding, QOS etc. A better way to solve this issue would be:

1. If ISP's router is a better device, then disable DHCP on the Wireless router and connect the LAN Cable from one of the LAN ports of the ISP's router to one of the LAN ports in the Wireless Router, essentially making it act just like a Access Point.

2. If the Wireless Router is better (generally the case), then disable DHCP on the ISP's router + put it in bridge mode. This way, it'll only act as a Cable/ADSL modem and not a router. Connect the Lan port of the ISP's router into the WAN port of the Wireless Router and configure the ISP login settings in the Wireless Router.

Configure the advanced router settings like Port Forwarding, QOS, VoIP, etc on the Wireless router and be well on your way.

Hope this helps.
