First try a good Cat 5e or Cat 6  Ethernet cable. Also look at the inside of the ethernet connectors and ensure there are no bent pins. Swap the Ethernet cables to a different port and power cycle to see if that changes things. If it is happening on one device, try a different device as it may be the device. If that does not fix it, then I would contact TP Link support.

Yeah, I'd have tried that but it is all hardwired devices only, all at the same time.

 

I have 6 devices hardwired. Everyone of them all at the same time lose internet, while the wifi stays on. So even the ethernet in must be ok or wifi would go down.

 

Maybe I'll just contact support and see what they say.

One other thing to try is to disconnect all the hardwired devices and connect half of them and test. If bad disconnect them and connect the others for a test. If good, add back the others one at a time to see if one of the devices is causing an issue on the Ethernet bus.
