I have a dsl modem supplied by my isp.
it has 2 outputs - an ethernet lead to my set-top box (which requires an isp assigned DNS) and a usb lead to my pc.
I have it working fine.
However i also have a laptop which i wish to connect wirelessly and have internet access from the same account.
I have bought a wireless router but it doesn't have a usb input so I can't do the usual thing of connecting the router to the modem and taking the feed to the set-top box via the router as the router changes the dns the set-top box requires to verify.
I also can't source any kind of usb to ethernet converter to plug straight nito the router
so my quesauion is this:
how do i set up my desktop pc to take the internet feed and relay it to a wireless router so it can supply my laptop with internet?

yeah... I had a mate with the exact same prob, I had to screw around with the TCP/IP settings to get it to work.
(im assuming the modem is from BT ;) )

you set the modem connection up with ICS (internet connection sharing)
you then plug the computer with the modem into the router, and I think this is how it goes:

you LAN card should have the settings:

IP: 192.168.x.2  (x is usually 1 or 0.  you can find out what y is by finding out your routers IP, e.g. if you router has the address then your LAN card should have

Gateway: (same as your modem connection usually somthing liek 81.?.?.? I cant remeber what the numbers are in the place of the ?s )

DNS: (same as your modem connection usually 212.13.?.? or somthing)

then for your laptop:

IP: 192.168.x.3
Gateway: 192.168.x.2
DNS: 192.168.x.2

I think thats how it goes, let me know if you have any probs and we shall see if we can get this sorted :)

hope that helps


note: usually if you have any probs you can solve the issue by playing around with the IP configuration.

If you have an Ethernet card in your desktop then easiest way may be to use the wireless router as an access point something like this http://www.tech24.arce.co.uk/rap.htm

Then connect desktop pc to a LAN port on the router, setup your Internet connected PC (Master) and your laptop (slave) like this http://www.tech24.arce.co.uk/proxy.htm

Just to add you wouldn't use the WAN port of the router in this setup.
