Internet connection sharing with windows XP home edition with a router
Using a router for a wireless and wired LAN
Usually a router is used to connect a network to the Internet or to connect a LAN to a WAN ( local area network v. a wide area network) A crossover cable is not needed anywhere.
However I have a Sprint air card USB which the computer considers a dial up connection even though it is broadband. This cannot be connected directly to a router therefore I must enable Internet connection sharing to get other computers on the network to the internet. This computer that accesses the internet is called the host computer. Therefore under control panel network connections the Sprint network adapter which makes the Internet connection is selected and ICS is enabled (under the advanced tab). When ICS is enabled on the host computer it automatically assigns an IP address to the other network adapter (the LAN) 192.168.0.1 I only learned later that you have to be careful if you have multiple connections which one that IP address was assigned. I found on my computer that it gave that address to a nonfunctioning wireless network adapter. Therefore after much trial and error I found this problem and disabled that nonfunctioning network adapter. The LAN adapter then was configured manually under TCP/IP properties with that proper IP address of 192.168.0.1 and the same for the DNS server address. The gateway goes blank and cannot be assigned since this is the gateway.
The router was then assigned a static IP address of 192.168.0.5 for its LAN set up and under the basic settings was assigned 192.168.0.9 for its IP address and DNS address of 192.168.0.1 gateway and primary DNS server (subnet the usual 255.255.255.0). Somewhere on the Internet I read that the LAN DHCP should be disabled but that is not necessary and I have a network music player that cannot function unless the IP address is assigned by the LAN server ( which is the router in this case).
On a computer connected to the LAN via the wireless router (called client computer) I have configured it as follows under Windows XP. Internet Explorer under tools\Internet options\connection is set to auto detect settings and is unchecked for using a proxy server. Under my network places select View Network Connections then select the wireless network connection use to connect to the LAN via the router. Right-click and select properties scroll down to Internet Protocol (TCP/IP) and select it. Then click properties. I chose to assign an IP address of 192.16 8.0.8 though it does not seem to be necessary. Subnet mask of 255.255.255.0 with a default gateway of 192.168.01 and the Preferred DNS server must be 192.168.01
