Question

Two NICs, two routers, how simultaneous

by OldGuyOldBrain / November 9, 2014 2:54 AM PST

Windows 7 each computer has one wireless one wired NIC.
Router A is not mine and provides wireless access to the internet from each computer. This network is shared by others as well in the house. Uses 192.168.0.1 at the router and DHCP to serve up IP addresses.

Router B is mine and provides wired&wireless access for each of my computer to printers, computer harddrives and usb drive connected to the router. This router is set to 192.168.1.1 and DHCP to make it simpler setting up printers (some are older, read maybe even possible at all). Both computers are wired to this router, printers are wired or wireless as needed.

Problem: when the computers have the network wire plugged in, they cannot access the internet. (Names are not resolved to IP addresses and IP addresses are not reachable.) Unplug the wire and the internet works, but of course no network-harddrives or printers are available.

Wanted: to have access to harddrives/printers and to internet (but not letting everyone in the house -renters come and go- use my printers or have access to my harddrives.)

Tried: assigning static IP to the wired NIC. Result: wire plugged in, access to internet, but router B only an unrecognized network, NO access to printers or harddrives.

Tried: messing around. No way of knowing what I did or what results were. Decided to quit stabbing in the dark and search for help. No help found specific to this setup, but interesting info. So I'm asking.
It's got to be simple.

Level: Long ago in another life Windows NT 4 MCSE, a few years ago near dead sick, brain forgot a bunch, getting healthier working my way back. Don't know what I know, not know.

2 routers?

I wonder if the ISP would let you do that (just thinking out loud). Maybe I am not too clear as your objective (my brain is also getting older as well).

I'd consider the old way of setup rather that 2 NICs and resulting crash course in routing.

I'd think of router A's feed as the internet and wire it up like this.

Router A -> WAN port of router B.

Router B then supplies connections to my LAN.

2 routers and I'd rethink this one

In reply to: I'd rethink this one.

The ISP has nothing to do with it. As far as internet is concerned Router A is wired to their service. end of their concern.
Everyone in the house has wireless access ONLY to Router A and the internet.
I don't have the option of wiring Router B to it. I don't own it, it's locked in another room, etc.

Ending five years ago I did have this setup working somehow, but it's not a matter of going back, (the old way is not available) the whole system has been in mothballs for three years, and in between I was in a different house where I had full access to (for that house) Router A, and I did something different for Router B, maybe a hub which is no longer around. Can't remember those days well since I was so ill.

I went for a router because I remembered that the printers were so much easier to setup as DHCP clients rather than using static IPs. Plus there was something about Windows 7 not sharing harddrives well without a recognized network???

So it's a crash course in routing ... I'm good for that if you could point to some free online resources for Windows 7 routing. That would be worth my time for the fun of seeing how the brain functions.

It would be nice to hear it's possible somehow. So far it looks like a lot of similar situations just lead to frustration and reverting to Router A: LAN port -> Router B: WAN port. Which I remember trying way back when and giving up on that ... but that had to do with trying to get NAT to work on the far side of NAT ... if I remember correctly.

Then go for it.

For me the Router A to the WAN port should be fine. But let's see if you can solve it with dual NICs. I know I'd be done inside a few minutes with the A to the WAN.

Help, my PC with Windows 10 won't shut down properly

Since upgrading to Windows 10 my computer won't shut down properly. I use the menu button shutdown and the screen goes blank, but the system does not fully shut down. The only way to get it to shut down is to hold the physical power button down till it shuts down. Any suggestions?
