Some times even after I disconnect the cable and reboot the device it works but after a few minutes the WiFi disconnect again.

Hi  @Riley_S,

Thanks for the replay.

I tried most of the solutions you suggest for the third case but looks like they didn't help to solve my issue.

When I encounter this issue of no connectivity every night I check if the issue comes from the connection from the router itself but it didn't.

When I disconnect the cable from the device and connect it to my laptop directly the connection is stable with no interruptions.

I also tried to connect to the device via his IP address when the issue occurred but didn't succeed.

The page is loading but nothing shows up on the screen only when I disconnect the cable from the device and connect it back again I can connect to the device and some times even that not helping.

Also, for your information, I have two of these devices in my home. They are both the exact same hardware version and firmware.

And I encountered this exact issue in both of them at the same time every night.

The only thing that I want to try is to change the SSID from the SSID of the router and the other RE450 device in my home.

I will share my results tomorrow in this case.

Thanks for your help.

Niko
