I changed the internet provider. Before, it used a Sagecom modem, with WLAN deactivated and M4R as Wireless Access Point. In this new provider, they use a Huawei router HS8546V5. I performed the same settings, deactivated the WLAN of this router and placed the M4R deco of the room in LAN 3 and the bedroom M4R of LAN 4. When I use the Wifi or network cable output of these decos, after a time of use (on a WhatsApp call or connected to a VPN) my connection drops, I lose packets, but I don't lose connectivity with the device. I would like to know if anyone has been there and if there is any specific configuration to be done.
