I have had my router for nearly 3 years with no real problems. Firmware shows an update in December 2020.
Initially, I thought it was a 'one off' but the Hub is now regularly (at least weekly, sometimes more frequent) disconnecting some devices, specifically a printer and 2 laptops. All these are less than a year old. As an example, if I go to print something the printer does not show on the available printer list. The Hub shows it as 'disconnected'. If I try the printer settings, it sees the SSID but cannot connect to it. Restarting the printer has no effect.
The only consistent remedy is to restart the Hub which is annoying to the other users in the home.
2.4 and 5Ghz have different names for their SSID. Smart Setup is disabled.
Does anyone have any advice or suggestions?
Have you tried a factory reset by pressing the recessed button on back and holding 20/30 secs until lights flash. Remember to turn of smart setup and split the wireless network again so your wireless devices will connect automatically
My printer is again showing as "disconnected" on the router settings. Restarting the hub, as before, was the only solution.
