Windows 7: 2 routers, cant see computers on other router

This is more of a general networking question (I think) but I'll give it a shot here anyway.

I have 2 wireless routers/switches in my house. I have a router downstairs and one upstairs



My setup is currently like this
Downstairs:

• Computer
• Printer
• Modem

Upstairs

• computer
• HTPC (media center pc)

I use the printer on the downstairs computer to print everything, and this used to work fine until I installed a new router upstairs. My old setup was that upstairs I had a wireless router, and a separate switch, and the router was feed internet through the switch. Now that I installed a router/switch combo, I cant see any computers except for whats directly connected to the upstairs router.

How can I solve this so that I can again see computers on the other router?

I have a question, How did you connect the 2 routers too each other?

Don't use the WAN/Internet port on the router upstairs and turn off the DHCP server in that same router. And also change the IP address on that upstairs router. If the main router uses 192.168.1.1 as its internal IP address change the upstairs one to 192.168.1.2.

What I think you had before was a switch and a Wireless Access Point (Not a switch and router).

Doing what I say above will turn that router into a Switch WITH Wireless access point.

Awesome, that worked like a charm, and made sense as well

I did indeed have a WAP and a switch before

Thanks a ton.

You are welcome.
