I use 4 of the ax3000 routers as accesspoint mode. The wifi speeds are fast but some apps won't load on my phone and on my wife's phone when we are connected to the wifi of the ax3000 . When we turn of wifi and connect true mobile data the apps are working fine. When i connect to my isp router wifi i have no problem at all. Also on other wifi networks no problem. Only on my ax3000 routers. Already did a factory reset. What can be the problem here?
