JeffersLos Posted July 8, 2022 Posted July 8, 2022 A new Windows 11 PC, when left idle or put to sleep/on standby for around an hour, on wake up the ethernet connection keeps on cutting on and off every 5 seconds and does stop. I can connect through the Wifi, but that's not as good. Why does it do this and how can I stop it from happening? TIA.
OneMoreFarang Posted July 8, 2022 Posted July 8, 2022 I had a similar problem on a notebook some time ago. A new device driver fixed the problem. I suggest check windows updates (maybe some advanced options) and check for driver updates from the manufacturer. If you don't see any updates now then try later again. 1

Locate your network adapter, right click and select Properties. In the property sheet, switch to Power Management tab. Uncheck Allow computer to turn off this device to save power option. Click OK, close Device Manager. 1

Another PC is connected to the same router without any issue. I have swapped ports and still it is the same. What causes a Win 11 PC to flash on and off the ethernet connection? TIA.

Because I think the power saving option is only used if the computer is on and i.e. the cable is disconnected. Then the port would go to sleep - because it is not used. If the whole computer is sleeping then I guess there will be also power saving on that port. But I might be wrong. You can easily test it and I don't see a downside of testing it. Just make sure you keep a log of any setting which you change so that you can easily undo it if you want to do that. 1

It resets the network, then reboots the PC over around 5 minutes. 1
JeffersLos Posted July 28, 2022 Author Posted July 28, 2022 Everything was good, but I had an extra 8Gb RAM installed, taking it up to 16Gb (8Gb x 2) As soon I turned it on, the issue was back. Update driver. Already has the newest driver. Network Reset, as above. In Device manager, go to Ethernet properties and unclick 'Allow computer to turn off'. And it's still the exact same. Every minute the connection turns off for 10 seconds or so, then connects again. Another PC connected to the same router has no such issue (both cable connections have been swapped) One difference shown is the ethernet resource settings, the 2nd RAM stick shows as this. Right or left mouse buttons doesn't do anything to it. Any ideas?

Roll back and if that doesn't help make sure to try a few different versions both from Intel and your manufacturer if they offer it. 1
Bobbie Davies Posted July 29, 2022 Posted July 29, 2022 And you see why I live on my MAC. But seriously it does seem like a driver issue, but can’t rule out hardware issue. You could have a flawed or otherwise incompatible Ethernet card. Thinking about it, manufacturer flaw seems very possible.
Royl111 Posted July 29, 2022 Posted July 29, 2022 mate....maybe you will consider my answer as not competitive. but try not to use WIN 11 for a couple of years at least ????
JeffersLos Posted July 29, 2022 Author Posted July 29, 2022 Just to update. It's fine again. ???? The Network Reset changed the option in Device manager, for the Ethernet properties to 'Allow computer to turn off'. Doing a Network Reset, then going into the Device Manager and adjusting the ethernet properties solved it.

Sometimes i have to do several network resets and restarts before it connects. I have also tried the things you listed above with no lasting results.
