I have one spare wireless router (Aztech Wireless G Router) with one WAN port to connect to a separate DSL modem and 4 LAN ports. I was wondering is it possible and how to set up a wireless LAN just by using such router as I have no spare DSL modem to connect to the router?
P/S: I tried connecting my laptop to the router using LAN cable to set up the wireless but I can't access my router page (192.168.1.1). Do I need a DSL modem to access such page?

If you already have an existing router to handle DHCP and DNS, you can use this as a switch+AP. Simply plug a cable from one of the ACTUAL router's LAN ports into one of the LAN ports on the Aztech. From there you can log in and configure the router accordingly.
Be sure to disable the DHCP server on the Aztech so it doesn't try to hand out IP addresses. Some routers have a "DHCP Relay" setting just for this purpose.
NOTE: Be sure to leave the WAN port on the Aztech empty.
As to your PS: that wont work, since at the point you plug your laptop into the router it, by itself, has no IP address.
once you have it configured as above, the other router should assign an IP address to the Aztech. Use that.
Here is a good, but a bit verbose, guide on setting this up:
