Sharing files between PCs on two routers

January 13, 2011 at 01:05:06
Specs: Windows 7 32
I have two routers - one connected to internet using address, and one below it using address I would like to share files between them using Win 7 HomeGroup. If I hook both PCs into the same router, it works fine. Hooked to different routers they do not see each other. I've tried turning off DHCP in the lower router, but the PC connected to it still gets address starting with 192.168.0 (from ipconfig) and does not show PCs from top router.
Top router is SYSWAN 24 and bottom router is DLink 655.

If the two routers aren't connected then there's no way that devices plugged into them will see each other - how could they?

At the very least you need to connect the routers with a cable. It's possible that you might need also to configure the routing tables on the two routers or they may negotiate between themselves automatically.

"One router below the other" - I meant on a logical connection flow chart, not on the rack.

"Bottom router" uplink is connected to one of the "top router" 's down links.

This is due to the different subnets and the how routing works.

Usual solution is connect the downstream router via one of its lan ports not wan port with crossover cable. Disable dhcp on the downstream router and assign it a ip in the x.x.1.x network for maintenance access.

Answers are only as good as the information you provide.

Thank you!

That is a perfectly understandable and relevant answer.
I will try it once I find a cross over adapter.

I'd suggest that you have a look at the "Connect to Another Router" section of the manual for the 655 (p. 12). You shouldn't need a crossover cable (most ethernet ports are autosensing nowadays - the manual says to just use a normal cable).

Yes, that immediately works.

Thank you!

Thank you - that immediately works.

How much slowness and instability does it add to go through a hub?
I have the more expensive option of changing my top router to an 8 LAN SYSWAN unit which is more expensive, and for sure will solve my problems at max stability and speed.

Using the DLink in the past as a main router it was not 100% uptime, and file sharing was far from 100% - SYSWAN is much better.
How much will the computers connected to the DLINK set up as hub will suffer?
