Hi, welcome to the community.

“if I turn it off at night and not use it for a few hours, it loses connection with the router and my devices will re-connect to the router but have no internet connection"

Do you mean, that when RE450 is turned off at night, mobile devices can no longer get internet when they reconnect to the host router?

-If you restart the mobile device or Host router once, will it have an internet connection?

RE450 is designed to be on 24 hours a day 7 days a week 365 days a year.

Thank you very much and best regards.
