Network but no internet access

Hello good morning and good evening, as you can see I have no network with the PC in my bedroom (ethernet outlet on a Devolo 500 wifi) while the one in the living room is connected via wifi and my smartphone can connect just fine, the network passes no problem but on my PC not! I tried everything well almost but in vain. Guest of command admin
Ipconfig/netsh int ipv4/6 reset / shutdown -r
After that I thought I was saved I had internet but 5 minutes later this damned yellow triangle with no internet access

During troubleshooting they tell me the default gateway is not installed but from there I no longer understand anything

If someone understands me and would kindly help I’m open to it

Good: - Morning

- Night (but you won’t be able to reply then)

    Good evening, can you confirm for me, via the network card settings (Right-click Network - Open Network and Sharing Center - Change adapter settings (left pane) - Properties of your network card - IPv4 properties) that the assignment of addresses and DNS servers is automatic? If not, please check everything to automatic, check "Validate these parameters" and validate.

      Thank you, they weren’t on automatic for now, the network is working quite well and doesn’t seem to stop. I don’t know if this influences my situation, but in the settings of my card the "Microsoft Network Card Multiplexing Protocol" option is unchecked—is that normal or not? Thanks again

        If it helps, when I don’t launch Mozilla or Google the network works perfectly; I can play and use my online apps, but the internet makes me lose the connection.

        Good evening,
        delighted to have temporarily resolved your issue, but it seems relatively persistent...

        The connection appears unstable when a browser is launched... It originates from the machine... I cannot tell you more, unfortunately, I am not a network expert, even less with powerline adapters...
        Personally, I also have this problem with powerline adapters...

        Try re-synchronizing your powerline adapters (I can do no better than recommending you refer to the user manual for your powerline adapters). From time to time, they can be interfered with by devices that emit radio waves (Microwave ovens, etc...)

        Regarding the Microsoft Network Card Multiplexing Protocol, this protocol remains unnecessary for the proper functioning of a network card. Enabling it amounts to disabling it, the system prompting the user to do so automatically.
