Hello everyone!

I'm having an issue that is driving me crazy for the last 6 months.

I have a modem/router from my ISP in argentina (TELECENTRO). It is a Sagescom Fast 3896 (WIFI 6 model). from that modem/router I connect the Archer AX50 to one of the gigalan ports of the Sagescom into the WAN port of the AX50.

The AX50 is in AP Mode in the "Operation Mode" Menu.

I have a notebook with UTP connected to the AX50 and a cellphone through WLAN

The problem is that randomly keep recieving the "Phone without connection. Check an active connectino to Internet" in the web application. I can be connected for about 1 o 2 hours without the message and suddenly start to show up like every 5 or 10 minutes.

The cellphone is 2.4 only. 

Things that I already done:

Disable the WLAN from the AX50 so the phone can connect to the wifi through the Sagescom > works!

Disable the Band Steering in Sagescom and Smart Connect on AX50 > fail

Get 2 different SSID for 2.4 and 5 on both AX50 and Sages > fail

Made the WLAN open with no encrypt > fail

Set AX50 as router and create separate networks > fail

Check cellphone deep sleep app and settings > fail

Check the cable from sagescom to ax50 > same issue

Is really annoying this behaivor. 

Any suggestions? 

Thanks in advance
