I have a Nokia 5G21 Gateway with an ethernet connection that feeds a switch in my home office. All other devices (phones, laptops, wireless printer) are connected via wifi. The gateway shows 6 devices connected via wifi, and 3 via ethernet -- that is the correct number of devices.
All devices have internet, I can connect to the web interface at http://192.168.12.1 from any device, but the wifi devices cannot ping devices on ethernet or vice versa.
This had been working until recently. This happened one other time, rebooting the router fixed the issue then, but didn’t work this time. Any suggestions on how to keep this up and stable are appreciated.
