My friend has a win xp laptop that connects to the internet through a d-link wireless adsl router - the connection is set up as an internet gateway. Is it posible to also use this to connect a win 98se desktop using a wireless card and share the internet connection. The desktop seems to connect to the router no problem but am a bit baffled as to how to set up the internet connection on the desktop machine. Any clues appreciated I think i know all the ip addresses and subnet masks I may need etc....

a wireless and wired connection are configured the same. here's where you go and what you do:
1.) install the wireless card and drivers.
2.) on the computer you just installed the wireless card in, right click network neighborhood and select properties. now right click on the local area connection that is set up with the wireless card and select properties. now highlight TCP/IP and click the properties button.
3.) if the router is set up with DHCP then click the dynamic IP radio buttons for the IP address and the DNS server IP address. if no DHCP is available then your going to need the IP address of the router. with that said, were going to fill in the following fields:
IP address: this will be the same as the router IP address except for the last number {octet} mine is 192.100.100.30
SubNet mask: chances are it is a class C 255.255.255.0
Default gateway: The ip address of the router like mine is 192.100.100.1. this gives you internet access.
DNS Address: The IP address of the router goes here too.
so the Default Gateway is the door that lets you out to the internet, the subnet mask defines the network ID, the IP address defines which computer you are on the network {i'm computer 30 on the 192.100.100.0 network} and the DNS server IP address is the router again because it will handle all requests for name resolution on behalf of you, to the DNS server that your ISP handles. so if you want to go to GOOGLE.COM then your router forwards the DNS request to the ISP's DNS server and you then find GOOGLE.COM
hope this helps
good luck
