MT1300 Connection Issues: WAN & Wifi connected but no internet?

MT1300 in repeater mode (Wifi). I have tried all the firmware versions and they all have the same issue.
Admin Panel shows WAN (via Wifi) is connected with internet
Wifi is solid and clients stay connected
Internet to the clients keeps dropping (every 3-5 min) and the light on the front of the modem goes from solid white to flashings white.

I’ve monitored the WAN Wifi source and it does in fact have internet when this happens.

Can you give more details?

e.g. what is the upstream wifi and what is the IP the router got?

Also ssh to the router and get the log using logread

Is there a captive portal in play here, and have you passed through it?

Yes there is a captive portal. The problem persists after passing through.

Are these the only log? Is there any dhcp request sent?

I ma not sure why but can you reset the router and try again?

Also flashing white LED is strange.

I’ve reset the router and it continues. I’ve also used every firmware version available. It happens on all firmware versions. I’m not familiar with DHCP but below is the part of the log that mentions it.

Is it possible to set up a remote check using anydesk? pm me if you can
