    Ethernet cable shows as disconnected


    Sometimes when I start my PC, or I start it from sleep, the Ethernet shows as unplugged. If I go into device manager, it shows a yellow triangle with an exclamation mark in it (attached image). If I 'Scan for hardware changes' it starts to work again, until I shutdown or start from sleep.

    I have updated all drivers, and installed all windows updates, but it still does it.

    Any ideas?

    Did you check the Power management setting to make sure that it is not set to have the computer shut it off to conserve power? Windows 7 ethernet goes to sleep! [solved]

    A lot of times the Gateway or Switch will go into "Green" mode, when the computer stops pinging back, when the Gateway sends out a request for Ping Alive, to see if the device is online. The same with the adapters.

    Any device on the computer that Power Saving can be set for, should be unchecked. You can also go into the Advanced power settings and make changes to all settings for the system.
