I've been using a Chromebook for remote work, connected via a wired Ethernet adapter since my Wi-Fi is spotty in this part of the house. The setup used to be rock solid, but recently the Ethernet connection drops every 10 minutes or so, forcing me to unplug and replug the adapter. Meanwhile, Wi-Fi stays connected and stable if I switch back to it. I tried swapping the Ethernet cable and even tested the adapter on another device - both seem fine there. I updated the Chromebook OS to the latest version too, but the issue persists. I want to stick with wired for better speed and stability but it's just unusable like this. Has anyone seen their Chromebook act up like this with Ethernet adapters? Are there any hidden settings or power management quirks I should check? Could this be a hardware fault on the Chromebook side or something fixable in software?

Sounds frustrating that the Ethernet was solid before but now drops so regularly. Since you’ve ruled out the cable and adapter by testing them elsewhere, it does lean toward either a Chromebook hardware issue or some software glitch. Have you tried a full powerwash (factory reset) on the Chromebook? Sometimes network drivers or settings get wonky after updates, and a reset can clear that up.

Also, check if there’s any power management setting or USB selective suspend option in the Chrome OS flags or experimental features - sometimes the system tries to save power by cutting off USB devices, which could cause the adapter to disconnect. If that’s not accessible or doesn’t help, you might want to test with a different brand/model of Ethernet adapter just to see if the Chromebook is picky with certain chipsets.

Others here have mentioned flaky USB ports causing similar issues, so maybe try plugging the adapter into a different USB port if possible. If it keeps happening, it could be
