My WiFi keeps dropping out, this happens most days and requires a router reboot to fix it. I have tried changing the channel but this still happens, I have ran a wireless network scan and there are no known networks clashing. Network log below.
Wireless interference can come in many forms that won't show up on a wireless network scan. Cordless phones, baby monitors, car alarms and microwaves all have the potential to cause interference but will not show on a scan.
Do you have any devices connected by Ethernet cable to the hub? If so do they also lose connectivity? Knowing if a wired device drops out helps to pinpoint if the issue is just with the wireless or possibly your line.
Posting the downstream and upstream screens showing power levels might be helpful to see if the levels are all healthy.
