Internet Connection Sharing in Home Network?

Question

I have a small home network that consists of two windows xp computers. "Computer A" connects to a cable modem by USB. It also connects to "Computer B" through a crossover ethernet cable between the ethernet cards. I can see the A's files from computer B and vice versa, but even if i disable all firewalls and allow internet connection sharing, computer B doesn't get internet. The Set up looks like this:
Computer A obtains IP and DNS automatically from the cable modem. I set Computer A to have an IP of 192.168.1.10 on subnet 255.255.255.0 (no default gateway or DNS server) on the connection to computer B and I set computer B to have an IP of 192.168.1.11 on subnet 255.255.255.0 (no default gateway or DNS server) to connect to computer A. I have tried using computer A's IP address in the default gateway for computer B, but that didn't work. The problem might have something to do with the DNS i think? I have no idea. Please leave detailed answers, I'm no good with comps. thanks

Answer 1

I think you are gonna have to get a router so that the internet connection passes through both computers at once. Either that or a hub. And i would also recommend that you get rid of the USB and try for a CAT 5E connection so that your speeds are faster, but i understand if thats not possible (due to money or wutever)

You are so full of baloney!

Configure the usb adapter to DHCP, and configure the ethernet adapter using a static ip address. The ethernet adapter will need to be on a separate network from the usb adapter (usb adapter = 192.168.1.10, so configure the ethernet to 192.168.0.1 for instance). Once that is done, share the connection, disable firewalls. Now you will want to configure computer B to have an ip address of 192.168.0.x (where x is anything from 2-254). Set the default gateway on computer B to 192.168.0.1, and you will need to hardcode your dns server into computer B as well (this can be found by going to start -> run -> cmd -> ok and typing ipconfig /all). So the computer B configuration will look like this in the end:
IP address: 192.168.0.X
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.0.1
DNS Servers: same as usb interface on computer A (or you can use a public DNS server like 4.2.2.2)

once all this is configured, make sure you can ping 192.168.0.1 (start -> run -> cmd -> ok type ping 192.168.0.1)
if you recieve replies, try pinging out to your DNS server address. If the DNS replies, then you should be able to surf w/o any trouble.

I run this particular configuration on my network, where my computer A goes to a switch connecting to my other computers (we'll say B, C, D and E), and the nice part about it is you can monitor all traffic going across your internet connection ;)

Answer 4

That speed would probably be ok for playing one game at a time but if you think you'll be playing a PC game online at the same time as your brother is using Xbox Live then you'll probably need a faster connection. This will depend on the games though and how much network traffic they generate. Those prices also seem very expensive for such a slow connection. I have to admit I'm from UK so I don't know what prices are like in the US but it would be a total rip off here.

Answer 5

I have actually set this up and made it work. Did you run a network setup wizard on both computers and share your inter net connection. If so, are both computers up and running? You cant run "B" online without "A" up and running. If that is not the case, then your are missing some software that should be in your networking setup. But I would suggest a router to make it really easy. And get rid of that usb modem hookup. That is real slow!!! Might as well as use snail mail. Good luck

Answer 6

For goodness sakes Andrew, go buy a Linksys router and let them connect independently thru the router. Then they can connect independently and you don't have to have both computers running.

Answer 7

Get router and stop torturing yourself.
