I recently added 3 new computers to my network. I already had 3 so I had to add another router to my existing adsl modem/router which has 4 ports on it. I simply plugged the new router into the free port on my original router and then plugged in the 3 new computers to that. Everything seemed to work fine (all the computers can access the internet fine) The original router is a BT gateway and the new router is a sitecom dc202. The problem I now have is that the computers attached to the original router can't access shared files or printers on the new router and vice versa. There seems to be no way that they can communicate. The compuetrs on the new router all have ip addresses in a different range from the original. Both routers use DCHP. Any ideas would really be apprecited as I know nothing about networks. I thought these things were quite automatic but obviously they are not.

Hi Hibernian I think you may of gone overboard with your solution, which is why your having probs. I would of gone down the road of installing a 5 port switch, such as a Netgear FS105 for around 25GBP. I would of plugged this Netgear into your existing BT router and that would of given you another 5 ports to use. Which will use DHCP from your existing BT router, and then you would be able to see your shared files/printers etc more easily, as they are on the same IP range. I'm sure there is a solution to the problem, using the gear you have purchased, but im not familiar with the road. Can anyone else concur that this would be a more sensible option ? Si

Yes, you should have just bought a switch which would have allowed you to basically add more ports to your existing router. If you can I would return it and get a switch. If you are stuck with the new router, then you should turn off the DHCP feature within the new router. Then attach the new router to the old router by LAN port to LAN port. Do NOT use the WAN port ont he new router. Doing that should make the new router act as only a switch. You may or may not need a cross-over cable. Michael J

Thanks guys. That is good advice. I will try to purchase a switch. I obviously didn't think thgrough the potetial problems before buying the router.
