you probably can't access the internet because your default gateway needs to be assign to your router. So for your default gateway set it to the ip of your router. I think you said it was 192.168.1.1

Hope that works for you

Basicly you should have the ip set like this
Computer 1
IP Address: 192.168.1.200
Subnet: 255.255.255.0
Gateway: 192.168.1.1

Computer 2
IP Address: 192.168.1.201
Subnet: 255.255.255.0
Gateway: 192.168.1.1

Also you can set a prefered dns to your router and it will figure itself out
so
Prefered DNS: 192.168.1.1

Default Re: 2 Computers on a network and then suddenly different addresses

Well, thanks for the effort. However, yet again, I lose internet connection and still cannot see the other computer.

I'm stumped by this. I really don't have a clue as to what is wrong, why it went wrong or how to fix it.

Any last thoughts would be greatly appreciated!

OK, I'll try my best here....
I have a modem: Motorola SR5101 and router: LinkSys BEFSR41

Computer 1 is running Windows XP Home
The details from IP Config /all on this computer are:
Windows IP Configuration

This is connected to Computer 2 via cable (which all worked fine!!)
Computer 2 is also running Windows XP Home

Running ipconfig /all on computer 2 gives the following:

I notice that the DNS servers are completely different here, apart from the other differences noted elsewhere in this thread. Might this be it?

Thanks

You say that computer 1 is connected to computer 2, so it sounds to me like your using internet connection sharing. You have a router so this isnt necessary. Connect both computers to the router via ethernet cables and then it should be fine.

Would do, except we use VOIP and need the router (My apologies, I forgot to add that bit of detail in there... we have a motorola voip box sitting between the router and modem.)

Ok so your going to have to use ICS then. Give the troubleshooter a go and let me know what happens, its normally good.
1. Click Start, and then click Help and Support.
2. Under Pick a Help Topic, click Fixing a problem.
3. In the left pane, click Networking problems.
4. In the right pane, click Internet Connection Sharing Troubleshooter and follow the instructions.

why not move the VOIP box to after the router. So you would have the modem plugged into the wan port on the router and then the two computers and the voip box plugged into the router.


I'm pretty sure that should work but let me know

Bozorg, thanks for the idea. I'll wait on that for the moment as it was all working fine without doing that before whatever it was went haywire.

Raffaz, I'll get to this in a while, things have got busy so I might not be able to respond just yet, but I will do this.

Thanks to both
