Internet access problem with a Linksys 54g router

Try setting the default gateway on the laptop to the ip address of your ICS gateway machine. Some routers separate the wireless and LAN connections on different subnets.

Try comparing your laptops ip information with that of one of the working wired computers. You can do this by going to Start up to run and type cmd then click "ok"

At the black prompt screen type "ipconfig" without the "".

You want to compare the IP Address, Submet Mask, and Default Gateway.

If one has an ip of 192.168.1.* and the other has 192.168.0.* then the wireless and wired are on seperate networks.

If the subnet masks are something like 255.255.255.0 and 255.255.255.1 they are on seperate subnets. Both should be fixable by putting in the same default gateway.

For example if your ICS gateway is 192.168.1.1 then set that as the default gatway on the wireless laptop. This can be done by going to start >> Control Panel >> Network Connections then right click your wireless connection and goto properties then double click on the "Internet Protocol (tcp/ip)" option. This will list all of your ip information (if its static) if its dynamic (ip gotten from router) you can still click "Use the following DNS server address" and set preffered dns to the gateway ICS ip. Or click "Advanced" and click Add under Default Gateways and add the gateway ICS ip there.
