Network router problem

TheDozen · Post by **TheDozen** » Sat Jul 27, 2002 1:44 am

I have been sharing a cable modem connection among 3 computers for some time now through a Linksys (BEFSR41) router and running WinXP. However, one day recently I discovered that only one computer was accessing the cable connection (its IP address begins with 192) whereas the other two communicate with each other but not with the internet (those IPs begin in 10, forming a private network). I have done a lot of swapping cables, attempting to repair the connection, etc., but have had no luck restoring the previous IP setting which is needed to bring the internet back to the remaining 2 computers. I know this is a cryptic post, but has anyone experienced anything similar? BTW if you need any specs, please ask..

Thanks,
TheDozen

Something don't make sense. I've got the same router with 3 comps on it and have never seen that yet. To me it sounds like you need to just set DHCP to on in the router and set the computers to auto detect from the router. If their setup manually assign them all an IP address of 192.168.1.100/101/102 and so on... Do this on all of the computers. It might also help to power cycle your router. Shut down all the computers cycle the power let it initialize then fire the computers back up to auto dect from the router. I think the reason it isn't getting net on the other 2 is because its not finding the DNS of the cable service but i could be wrong. I set my 3 up manually. DHCP was a PITA for me. It worked but i'd rather set it up myself so i know it works.

Thanks, Predator, for the advice.

The odd thing about all this is that the 3 computers have been successfully using the Internet for about a year, and only now has this happened.

Anyway, off to try that stuff out.

If the IP of the problem computers don't start with 192. then they probably aren't getting IPs assigned by the router. The Linksys uses 192.168.1.x by default.

Make sure you have TCP/IP on those systems setup to get their IP and DNS from the router. Make sure that DHCP is enabled on the router.

You could also set the IP, DNS and Gateway manually. Pick an IP address 192.168.1.x where x is a different number than used by the other systems.

Gateway will be 192.168.1.1 and DNS will be your ISP's DNS numbers

Thanks, FlyingPenguin...I dug another router out of the closet and had instant success. Obviously I had hoped to fix it in the way you suggested, but never had any luck altering the IP addresses.

Thanks again,

What was your previous setup? All you have to do is enable DHCP on the router, plug all the cables in, and set the clients to use DHCP. Not that difficult.
