AR750s Shows Connected But No Internet

I haveGl.internet AR750.
repeater mode.
Connected to ISP Hotspot
In the apartment building

I have 2 issues, one of them is major issue.

Minor issue, it shows that it’s offline and back Online every hour

Major issue: shows “all Connected” but no actual internet till I reboot. Once rebooted its fine. And it happens random

Any ideas? Suggestions ?

Is there a portal that you need to re-auth per hour?

There is no documentation that I can find to verify. But it seems to be the case with a CoxWiFi. I think it’s a time out lease issue. They kick devices off hourly to free up the bandwidth or for security reasons.
