About wifi configuration the best performance internet with deco are only with this wifi configuration:
* wifi base 2,4ghz+5ghz ghost only for administration and help for conection performance.
*Wifi guest same ssid with 2,4ghz+5ghz wifi for use
*Deco dhcp
Dns1 8.8.8.8
Dns2 1.1.1.1
*Deco ipv4
Dns1 1.1.1.1
Dns2 0.0.0.0
*IGMP option active from deco web administration
all this configuration and options in deco m9 plus are tested and only like this improve internet without problems and travels.
I strong recomend tp-link and deco service include and add defect configuration automatic in deco master.
Maby Using assistant in deco app asking information about connection type and router ip.
Assistant can done with configuration.
this automatic configuration process are needed and deco became premium wifi repeater. All for easy and ready service deco m9 plus.
