Sharing across routers

D-link / Di-604

Specs: Windows 7 Pro 64-bit, 3.0 Intel P4 478
DSL Modem to Netgear WRN1000 v.2
Netgear to D-Link DI-604
D-Link DSS-16+
I have a Netgear wireless router connected to a DSL modem. This runs internet to 2 computers in that part of the house off port 1 and 2. Port 3 runs to another section of the house (upstairs) to the WAN port of a D-link DI604 which runs another set of computers.

I can get internet to all computers but I cannot share my folders to the upstairs computers. If I disconnect the d-link and plug an upstairs computer to port 3 of the Netgear then the sharing resumes. How can I make all of the computer talk to each other.

NOTES:Keep in mind that if you suggest ip or mac changes, I will need to know how to do it as well as this is my first networking project other than setting up a crossover cable. One of my upstairs computers has dual 10/100/1000 Ethernet ports. I also have at my disposal a D-Link DSS-16+ 10/100 Switch II.

Any help on this would be greatly appreciated. Thank to all

Edit: All computers run WinXP Pro SP3 or Win7 Pro x64

You probably have DHCP enabled on both routers. You need to disable it on the upstairs router so the computers upstairs get their DHCP address from the router downstairs and they should then be able to share.

The routers manual will tell you how to disable DHCP

Sorry but that will not work since the 2nd router is connected via its wan port. DHCP could not "passthru" from the first lan to the 2nd.

This suggestion would be supported if crossover cable was used between lan ports of both routers.

Easiest thing to do is replace the 2nd router with the dlink switch. Then everyone is on the same subnet as router1 lan.

I missed that bit about the WAN port. In which case plug the cable to the router upstairs to a WAN port and then all computers will be on the same network. The router with DHCP disabled is then just acting as a switch.

A cross-over cable may or may not be needed, depends if the router has auto-sensing ports

After fighting the admin rules inside the router I finally managed to disable DHCP setting. This did not put me on the network though. I read elsewhere that I needed to remove the "from Netgear port 3" line from the d-link WAN port to the d-link LAN port and this made everything work just fine. I was able to use the normal cable and not a 50ft crossover, thank goodness. Although knowing that that LAN port is wasted does bother a part of me (pseudo-aesthetics only, kinda like tieing up wires that will be hidden behind walls).

Thanks for everything, my headache is slowly retreating

The following is the best advice:

"Easiest thing to do is replace the 2nd router with the dlink switch. Then everyone is on the same subnet as router1 lan."

If however, you don't want to buy a switch and insist on using the router, connect them LAN port to LAN port using a crossover cable. Click on my name above in my response and read my "how-to" guide on adding a second router and pay attention to the LAN to LAN scenario.
