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

That’s really annoying, especially since you’ve already ruled out the cable and adapter. One thing I’ve noticed with Chromebooks is that sometimes the USB ports can get a bit finicky after updates or over time, causing weird disconnects. You might want to try a different USB port if your Chromebook has more than one, just to see if that helps.

Also, since your Wi-Fi stays stable, it might be worth checking if there’s any power management setting that’s putting the Ethernet adapter to sleep. Chromebooks don’t have many user-facing options for that, but sometimes disabling any battery saver modes or extensions related to network management can help.

If none of that works, a powerwash as @zo348 suggested could clear out any lingering software glitches. It’s a pain to set up again, but I’ve had it fix weird network issues before. Fingers crossed you get it sorted without too much hassle!

That regular 10-minute drop sounds like something’s triggering a timeout or power-saving mode on the Chromebook’s USB port. Even if the adapter and cable check out elsewhere, the Chromebook might be putting the Ethernet adapter to sleep to save power. You could try digging into the Chrome OS flags or developer settings to see if there’s a way to disable USB selective suspend or any network power management features.

Also, if you haven’t already, test with a different USB port on the Chromebook (if available) just to rule out a flaky port. And since you updated the OS, it’s possible a recent update introduced a bug - maybe try rolling back or checking the Chrome OS forums for similar reports. A powerwash is a bit drastic but sometimes clears out weird software glitches that updates bring along.

@zo348 nailed it about the powerwash - I've seen Chromebooks act flaky with Ethernet after updates, and a factory reset sometimes resets whatever driver hiccup is causing the drops. Before going nuclear though, it might be worth checking if any Chrome flags related to networking are enabled or if there's a background app interfering with the adapter.

Also, since the Wi-Fi stays stable, it could be a hardware port issue on the Chromebook itself, especially if the Ethernet adapter is USB-based. Maybe try a different USB port if available? If the problem persists even after a powerwash and port swap, it might be time to reach out to the manufacturer or consider a USB hub workaround.
