2 routers and a switch crashing Win7...

December 3, 2010 at 07:15:55
Specs: Windows 7
Hi,
I have been setting up a network at home.
It uses 2 routers and a switch.

Router 1 has printer and 1 PC and a line out to go into router 2. It is configured and has 192.168.1.1 as IP

Router 2 takes the line out from router 1 and (into slot2 ie. not internet in) and puts a line out to another PC, a WDLive box and a switch. all using regular cables. 192.168.1.2 as IP

The Switch is intended to have a internet tv on it and an xbox. I did not wire the switch and I know nothign about them it was just installed for me by the guy doing some work at my home.

It all seems like it should work ok but PC #1 keeps freezing (screen there but mouse or kjeyboard do nothing)and if I unplug the connection between router 1 and 2, the PC is stable.

I want to know how to fix or debug this issue.
Is a third router instead of a switch what I need?
IS there a way to see a log from a windows freeze

Why do you need 2 routers?
If you'd like to connect WDLive to your computer, you can simply connect it to the 1st router by wire or connecting the switch to the 1st router by wire.
The 1st router also has to be connected to your internet plug by using a lan cable from the routers wan port to the modem.

I would like my WDlive to be able to access content from 2 PC's and it is on a different floor.
Yes the first router is connected to a modem. modem out to the internet(in) port on router 1 using regular cat5 cable.

Ok so when I get it right, the routers are connected by wire from LAN port to LAN port, right?
Is DHCP disabled on the second router?
You should only run one DHCP in the same network.

Lan port to Lan port is correct.
DHCP as well as any firewall are disabled on second router.

The description of pc1 behaviour indicates a malware or virus infection.

If that were true, would you expect that after the PC freezes I should be able to reboot and if I unplug the connection between router 1 and 2, the PC is stable?
Also, is it an issue that the switch is connected to a router with DHCP disabled?

Make sure, that the computer uses another ip address than the router1 or router2.
IP address conflicts can cause windows to freeze, if one of the running services is trying to connect to the internet, but can't.
In that case, Windows is nearly unaccessable.

Yeah, I was just wondering about that. I was wondering if I may have hard coded myPC1 IP in the first router a long time ago and never swapped it back and I am getting a conflict.
I had dismissed that idea because I had recently re-installed Win7 and I know I haven't set a Static IP on Windows.....
I'll check that tonight.

if there was a ip conflict you would get a popup message to that effect right from the gitgo.

you only have one dhcp server which is your main router

If as you say when you have isolated the main router to just pc1 and the printer then it would appear the traffic from router2 and what is attached to it is causing pc1 internet access to be throttled.

it is not clear in your posts what you were doing with pc1 when it froze.
If you were not on the internet at the time I come back to my first suggestion.
If the freeze is while web searching you have a upstream saturation problem.

Next step would be to leave the connection between 1 and 2 active when you have a freeze but disconnect one device at a time off router2 to see which is affecting the traffic and the freeze

I do not know why you need 2 routers at all!! I have One router on my first floor connected on one end to the internet telephone port and then my cable modem and on the other end uplinked to a gigabite switch. My network printer is connected to the routers port since it would not benefit from the faster switch and I have cat5e cable running to rooms on both floors with additional switches that were added upstairs to expand the number of ports upstairs so laptops could also now be plugged in without additional wire runs. This set up has been running and expanding over the last 8+ years without problem.
You really need to unplug your second router and use the switch you already have to make your split upstairs between your computer, TV, and xBox on your existing cable run. This should eliminate that potential conflict and either solve the problem, or at lease take that complication out of the equation. A switch is like a smarter hub that has better traffic control to eliminate conflicts or lost packets and is all you really need upstairs, not another router.
The reason I ran multiple lines upstairs when I moved in was to maximize the connection speed between computers since I have a drive in the main family computer that acts as a back up destination for all. I all works.

I run Tomato firmware to get around throttling by the Telco.
The router in question has no N wireless. I bought a second router because I wanted N wireless...running a cabled network was not in the cards.
We had a flood and dudes came in to my house so I paid then to run a network, They f---ed it up a bit so basement electrical room receives a line from my Tomato router.
3 lines leave that room. one for my wifes office, one for my family room and one to the new basement home theater. The home theater needs at least 2. and I would like to have a few open ports for laptops and various devices. So they put a switch in the home theater room. I could use a switch in the electrical room but I have that nice N router and it is still nice to have N wireless for blackberries and assorted wifi things.
If I were to get a second switch to put between my router and the theater switch, do you think that would fix the problem?

You can always add a switch to an existing switch for additional ports or multiple ports in another room via a branch off a switch.I did not realize that the 'second router' you were referring to was a wireless (we run a couple of them at work on a network), you probably just need to get into the routers set up and study the manual (or website) for the setup on an existing network. Remember, what you have set up is a pier to pier network rather than a server network, but most should apply the same since your primary router is taking care of DHCP for your network (or should).

I upgraded the firmware on the router and ran a few tests and found that something between router2 and the devices attached to the switch is an issue. I have unplugged the switch and have not crashed in several hours...
Haha, within 5 mintes of typing this, my wife jumped on her computer and mine froze again......D'oh.
I am back to the same questions

I want to know how to fix or debug this issue.

IS there a way to see a log from a windows freeze?

what were you doing when it froze? web surfing or not?
does it ever come out of the freeze?
can you bring up task manager during the freeze?
if you swap your computer for your wifes does hers now lockup when you use yours?

Is your primary router actually assigning the addresses on your network (VERY IMPORTANT)? Have you looked in your router's set up to see if it shows any conflicts? Try unplugging power to all of the routers/switches and plug in the primary router first with one computer plugged in (make sure the router assigns the address set TCP IP as needed), then add one switch and then the other computer (check address is assigned by the router) then add the wireless router and any wireless devices, then other devices.

Check where your DHCP range starts on our no# 1 router. It has to be above 2. you can't have static addrs in the same range as the DHCP range. Some routers will not work if a 2nd. router is connected behind it. Speedstream being the one I have seen.

Appologies.

What I meant by throttling was the Telco's traffic shaping stuff purposefully slowing down peer to peer connections ie. torrents.

When it freezes I have been:
surfing or not surfing, looking at my network diagram or doing nothing when my wife jumps on her computer and closed her network diagram.

Since upgrading the firmware on router 2 and disconnecting the switch, I have found a driver upgrade for my network card.
It has been stable for a day since! I will stress it tonight and have the wiring to the switch checked.
On the weekend I noticed it seemed intermittently connected. The guy may not have done the wiring properly and as a result I may have a bunch of noise on the line causing these issues.
