  1. Windows 10 No Longer Connects to Ethernet and WiFi


    This week brought Win10 ver 1903 and I can no longer get WiFi to connect if the ethernet cable is plugged in. If I boot with ethernet, manually trying to connect WiFi silently fails. If I boot without ethernet, WiFi is automatically connected yet drops if I plug in the ethernet cable. Both the WiFi and the ethernet work fine by themselves, just not at the same time so I don't think it is a driver problem.

    Any suggestions would be appreciated

    :)

  2. Windows 10 No Longer Connects to Ethernet and WiFi

    For a number of months I have used an ethernet connection to a device in my lab and a WiFi connection to the Internet via a DSL modem. Upon boot up the ethernet connection was on (albeit without Internet) and I just manually connected the WiFi to the DSL
    modem. Worked fine.

    This week brought Win10 ver 1903 and I can no longer get WiFi to connect if the ethernet cable is plugged in. If I boot with ethernet, manually trying to connect WiFi silently fails. If I boot without ethernet, WiFi is automatically connected yet drops
    if I plug in the ethernet cable. Both the WiFi and the ethernet work fine by themselves, just not at the same time so I don't think it is a driver problem.

    I searched for any others finding a similar problem with 1903, but do not find any. I do note earlier advice to add the fMinimizeConnections=0 register key and tried that. No luck with that.

    Any suggestions would be appreciated,

    Richard,

    Thanks for the suggestions. I must say you cast a pretty wide net there.

    I have run the network diagnostic with ethernet connected and WiFi not. It finds nothing useful. Both ethernet and wifi are configured private. Since each of the networks works by themselves the rest of the items suggested there do not seem relevant.
    It has something to do with the version 1903 and two networks at once.

    Windows 10 No Longer Connects to Ethernet and WiFi

    Windows 10 Ethernet connection randomly disconnects

    Hello,

    So this issue has been annoying me since i have changed my old i5-4670 with a ryzen.

    Ethernet: Realtek 8111H (MSI X370 Gaming Plus)
    Modem/Router: Airties Air 5760

    What i have tried so far to fix my issue:
    • Re-installing Windows
    • Updating Ryzen chipset drivers
    • Updating Realtek LAN drivers (both from MSI & Realtek)
    • Updating MSI' LAN releated drivers (MSI Gaming Lan Manager)
    • Replacing ethernet cable
    • Restarting router to factory settings
    Still no luck, keeps happening randomly. Sometimes it is stable for days then it is not stable for 20 mins. Happening when gaming or idle, or while streaming via steam link.
    Windows' own issue fixer thingy fix the issue for the moment, re-plugging the cable, disabling & enabling the ethernet adapter also fixes the issue for the moment.
    Also i am the only one having this issue in the network, TV and phones are still connected to wifi.

    It is started to be real annoying, so time to get help to fix the issue from TPU. Thanks in advance! *I Love TPU :lovetpu:
