    Disappearing Realtek Ethernet adapter


    Helllo,

    Am running Win7 Pro on a Gigabyte GA-EG45M-UD2H motherboard with integrated Realtek RTL8111DL gigabit ethernet adapter.

    Occasionally after walking from sleep I will not that the netork icon in the tray has a red cross through it with no internet access. Going into display manager shows no Network Adapter as if it just disappeared.

    Rebooting restores the missing adapter and internet access.

    Just wondering if there is a fix for this behavior? Note that it doesn't always do this after waking from sleep - only occasionally.

    Thanks for any suggestions!

    Hi and welcome

    Pretty sure the problem stems from the 'wake on lan' and 'keep lan alive' settings int the device
    one way you can check is to type ipconfig /flushdns and ipconfig /renew the next time it happens.
    If it fixrs it then those settings are the culprit. they both can be modified in the properies of the device

    Hope this helps and let us know if you need help with any of this
