@Graysilk Hi, As indicated in the "Change Mode" menu of the RE450, in Access Point mode the RE450 needs to be connected to the router by Ethernet cable.

@Navka Hi, Do I understand it correctly that you already has this problem with the previous firmware version and only later installed firmware version 1.4.3, which didn't fix the problem either?...

@Thenandouy Hi, Does the Archer AX72 have the "Device Isolation" feature? (I don't have this model myself, so i can't check) In case it does, then you could add the Archer AX53 as an isolated device...

@RS_03 Hi, According to the user manual for the TL-WR845N V4 the middle LED blinking can mean the following things: "Blinking Orange The INTERNET port is not connected while in Router Mode."...

@Gally I can't tell why the Tether app didn't lead you all the way through the setup. I rarely use it myself. In my opinion, the easiest way to connect a TP-Link range extender is by using the "WPS"...

@woozle Ok, I see now. While the Archer AX55 V1 allows to access QoS and Parental Controls from the "HomeShield" menu of the web management interface, the Archer AX53 V1 does not.
