  1. My PC's ethernet suddenly stopped working even though it was perfectly fine


    I checked if the cable was damaged and did everything like the other posts told me for example using bios, cmd, resetting the networks, and using device manager but it has been of no help. when I use the same ethernet cable to check if it is working on another device it is working perfectly fine I know that this is a PC issue so please help me. I did everything so if you can reply to me fast I would be thankful because I am going crazy. Plus the wifi is ok because I use a wireless lan card that works with USB. here is some information on my PC just in case Motherboard: Prime H670-PLUS D4. OS:

  2. Ethernet Cable Suddenly Stops Working

    Hi needing some help…

    A couple of weeks ago my Ethernet cable stopped working suddenly. I checked ports and they are fine. I used another cable and it started working again. Now the new cable has stopped working suddenly like the other.

    Any ideas what I can do to solve/stop this happening?

    I do have a switcher which is receiving internet fine however when using the cable in the 4 ports on the switcher none of them work with that cable.

  3. LAN Port stopped working suddenly

    Hello everyone,

    I came home yesterday to find that my PC in my specs had no Internet connection. I narrowed it down to be the PC itself and not any cables/modem/router etc. Now I went ahead and tried uninstalling and installing the LAN drivers again but it doesn't detect a LAN port.

    At this point it gives me an error message and states that the Realtek Ethernet Controller could be in "Deep Sleep Mode". To connect the cable to get it going. However cable is connected and verified to work.

    I've googled intensively and have tried many suggestions such as certain command prompts, registry edits, special permissions, and different methods of installing the drivers.

    Is my LAN Port dead, or something else might be the issue? Please note we did have a power outage yesterday as my other PC had also restarted like the one with the problem did. The second PC is perfectly fine though. Any other suggestions and/or advice? Thanks in advance. *Toast :toast:

  4. My PC's ethernet suddenly stopped working even though it was perfectly fine

    My ethernet connection suddenly stopped working. It was fine until yesterday.

    I have a Windows 10 Home Edition laptop connected to a 2G / 5G router. I've never had a problem with the internet before. My ethernet connection suddenly stopped yesterday, so I checked the settings and found it said "unidentified network, no connection" on the ethernet page, instead of my network name as usual. The strange thing is that I found that Wifi still works, so the router itself is not down for some reason. Tried reconnecting the ethernet cable to the router, then to the computer, even restarting the computer, but nothing worked. It's as if the cable just didn't recognize itself as plugged in, even though it was working fine yesterday morning.



    Your help would be appreciated.
