Ubee Modem Constant Disconnections

Hello Support,

I have a Ubee dual band router. The 2.4Ghz band is constantly disconnecting from the Internet on an almost daily basis, while the 5Ghz band is stable. I always have to unplug/plug the modem since there is also no apparent way of doing a soft restart. Also, it's not an option to ignore the issue because I have some devices that only use the 2.4Ghz band.

Hopefully, someone will be able to help,
