I've been attempting to link my PC through Ethernet for a full day. It's a custom-built system; the ASRock AB350 Pro4 board lacks built-in WiFi, so I've relied on external USB drives. I'm considering a permanent Ethernet switch but noticed some instability. The motherboard seems to be the likely culprit, as others report similar issues. I've tried reinstalling drives, updating IP settings via Command Prompt, and restarting both PC and router. On my PC, the Ethernet port shows green with blinking yellow, while the router's display is solid green. Could you advise on next steps?

No, the wireless adapter and Ethernet cable are not connected simultaneously.

I notice both my wireless and Ethernet connections appear in my internet icon. The Ethernet one shows "Undefined Network, No Internet Access." @C runchy Dragon
