Wireless router

Probably not.

There are several modes wireless uses.
Client(or managed) mode where the device conects to a base station. Such as your ADSL router or one of our nodes.

Master (also know as Access point mode infrastructiure mode and even base station mode) wich is the in charge device.

I'm ignoring modes such as monitor and WDS.

Your ADSL router is designed to run in master mode, and run standered networking services like NAT (internet sharing) DHCP (handing out ip addresses). Some of these devices like this do have options like Client/Bridge/WPA repeater on them. However these are usually only "acces points" not "routers". Because of the extra complications need to decide whether data in local net or internet they just assume you would't use a router for a cheaper devices job.

If you want to try you need to.
1) put its wireless in client mode.
2) DISABLE it fire wall.
3) tell it to gets its lan IP Dynamically.
4) DISABLE its DHCP server (not leaving this on will break piertopier)
5) DISABLE any routing/DNS funcntions.

If your wired PC connected to the router starts picking up and intenret address that looks like:
192.168.(node Number here).number. And getting a domain name of users.piertopier.net (use start, run, CMD to get a dos like prompt and type ipconfig /all to get your IP details.

The object would be to turn it it a reciever, and to bridge the lan port(s) to the wifi, and let piertopier handle the Addressing routeing DNS etc.

Obviously with the Router in Client mode (if it supports it) you would not be able to connect to it with a laptop would be in client mode as well.
