1) Keep ADSL router right where it is.
2) Disable the DHCP service on the old router. This is important! Take note of the ADSL routers LAN IP Address while your there, for example 192.168.1.xxx or 192.168.0.xxx also important!
3) Run ethernet cable from port 1 of ADSL router to WAN port of new router
4) Connect your PC to the NEW router and login to the new routers settings, your new routers gateway address is easy to find, just go to start/run type cmd then type ipconfig and press enter
5) Once logged into the new router, Set the WAN/gateway as static and assign it 192.168.0.2 (the block with 0 you will change to whatever your ADSL routers LAN range is).
6) Log into your ADSL routers settings page which will still be accessible and set the new routers assigned IP address as a DMZ, this will ensure that all traffic/data flows from the old router directly to the new one without any filtering.
After step 6 any device connected to the new router should be online and fully functional.
If you do not disable DHCP on the ADSL router then both routers will attempt to assign IP addresses to your devices and your network will be a mess.
Setting the WAN address as static means that the address will never change, and DMZ is short for Demilitarized Zone so basically were shutting your old routers firewall off because it will hinder your apps… two router firewalls on one network is too many, lots of traffic will never get through.

Assuming your new router has an Ethernet WAN/Internet port there are two ways of doing this.

Why do you want to connect a second router? The answer affects which solution is better.

Method One:

Connect a PC/LAN port on the old router to the WAN/Internet port on the new one. Make sure the subnet presented by the PC/LAN ports on the new router is different from the subnet on the PC/LAN ports on the old router. Also make sure the DHCP services are enabled in both routers. This may not work if the new router was provided by an ISP and the firmware is customised by the ISP. Also, there will be networking restrictions between devices connected to the two different routers.

Method 2:

Connect a PC/LAN port on the old router to a PC/LAN port on the new router. This might require a cross-over Ethernet cable. Set the new router on an unused address in the subnet of the old router. This address should be outside the DHCP address pool of the old router. Disable the DHCP service in the new router but keep the DHCP service enabled in the old router. The WAN/Internet port on the new router is not used. This will give you a single subnet across both routers and allow normal networking between devices connected to either router.

I hope this helps.

yes it should be possible to connect a second router to the first.This link should help

Probably, yes.
