No internet on ethernet ports apart from mesh router
This issue has really got me scratching my head because it's completely illogical. My father in law has set up a WiFi mesh which has been working fine for the last month or two and then devices star...
Only one wired device will work in modem mode, in this case the mesh system.
If you swap devices the HUB must be rebooted as it associates connectivity by NIC MAC address.
