      Wireless brilliant but ethernet cable drops connection

      Hi

      I have a wireless laptop and PC connected via the yellow cable. The wireless laptop works brilliantly with the Sky router. I can use it all day and 99% of the time it works perfectly well.

      However, when ever I use the PC the connection drops after 10-15 mins, and then stays off until the PC is switched off. Within 2 mins of switching off, the i light comes back on - 100% of the time.

      Now use the laptop - no problems, stick the PC back on and within 2 mins - no i light again.

      Yesterday I tried to disconnect the yellow cable but amazingly the light goes off when the PC comes on. What in my PC is interfering with the router? There's no wireless components or bluetooth. I've disconnected the wireless keyboard and mouse - Bizarre and its driving me crazy as its a work laptop and my wife has no internet when I'm at work!

      Please help!

      Does the PC have a modem that is still connected to the phone line?
      If so try disconnecting that.

      Is this an ongoing problem or something that has started recently?

      How old is the PC and how much use (turned on) has it had?

      From your description it sounds like that as the PC warms up something (probably smoothing electrolytics in the power supply) is failing and allowing the computer to radiate interference that is upsetting the broadband signal.

      Switch mode power supplies are notorious for radiating unwanted cr@p and electrolytics do have a finite life.

      If you are able to and feel confident enough borrow a suitable power supply and exchange it as a test.

      How is your internal wiring?

      It is possible that a small increase in unwanted radiation from the computer is enough to knock out your broadband.

      Can you post your router stats.

      If you log into the router status page and then turn on the cold PC you will probably see the Noise Margin dropping as it heats up before the connection drops.

      What OS are you using?
      Try uninstallling and re-installing the network card. Use the latest drivers from the manufacturers website.
      Check in the Network cards properties and power settings that nothing is set to turn off the network connection.
      It could be a dodgy port in the router. Try a different port.
      Go to Control panel>Internet options>Connections tab and select 'Never dial a connection'. Your modem may be trying to dial and knocking out your LAN connection.
      Failing these, it may be a hardware problem, either the network card, the cable or the router may be faulty.

      Try this... Open Device Manager and open the Properties of your network card. Select the Advanced tab, then Speed/duplex settings, and change the setting to Force 100 Full Duplex. See if that makes a difference.
