Second PC stops router ADSL connection

  malynx 10:20 03 May 2009


I have a two PC network that connects to the Internet via a router.

Two days ago PC#2 was using MSN messenger when it suddenly got disconnected.
The router's ADSL connection light had gone out
and neither rebooting the router, pc or unplugging the line from the phone wall socket would fix it.

I checked the router WAN settings
and the PC's Network Settings and everything appears to be in order.
Except the router and thus PC#2 fail to connect to the Internet.
I have tried usiing an alterantive DNS too, to no avail.

PC#1 will connect to the Internet through the same router - as long as PC#2 is turned off.
Turning on PC#2 causes the ADSL link to go down at the router!

To fix this - I need to turn off PC#2.
Unplug the ADSL line for a few mins, then re-plug in.
Then reboot the router.

File sharing between the two PCs still works.

Can anyone please help me to get PC#2 back online?

(automatic updates seems to have downloaded and installed Windows Powershell 1.0 the day before - if that's a possible cause?)

I have come across a weird situation before where a PC had developed a fault such that, when it was running, it interfered with the ADSL signal. It had nothing to do with how it was networked, but some component (and I can't tell you which) was oscillating at a frequency that effectively killed the ADSL signal.

Unfortunately that doesn't help you to sort the problem.
