@terziyski we are all waiting the new firmware, same problem, subscribed.

I connected the second router (second floor of the house, the other end of the diagonal of the house, latest update) AX53 via Mesh into an RJ45 socket and got higher speed (80 megabits versus 30 megabits).

But (!) the router fell off from time to time, it was impossible to go into the administration panel, the Internet clung for a long time from the first to the second router - all this leads to the opinion that it was just an access point, although there must be a serious conflict in the network, but it It wasn’t very noticeable (Google translator, I apologize in advance).

It’s a pity that I was not aware of the possibility of Ethernet Blackhaul for AX55/AX73, because they are not much more expensive, and building a mesh system from the X series deco is expensive.

I can suggest being as you said you have ethernet at the opposite side of your house would be to add another ax53 and put it in AP mode. 

thats the way I've done my network is I've got multiple routers in my property. 

I'm fortunate to have a large 4 bed house by uk standards, 

However I suffered massively with the "dad the wifi is bad" ect as ice got loads of solid brick walls from one end to the other  so I decided to buy my own gear, I opted for a ax72 and 2 c61200's 

Had the ax72 on the found floor as my main then I put both my c6 routers in AP mode. 

One on the second floor of my house and the other one at the bottom of my garden in my man cave, 

I can honestly say my whole property and some was covered in wifi. 

I've recently just upgraded the 2 c6 routers to another 2 ax72's and I've put them into AP mode. All my ax72's have the same ssid and same passwords. 

I've done it this way as where ever I am in my house or where ever I place devices be it smart bulbs or smart plugs phones or tablets ect they will pick the strongest signal available plus I've been able to utilise the lan ports for Internet devices down my man cave. Plus  I don't have to have multiple different ssid's for different routers. 

Yes you do have switching issues  sometimes with some devices but I've noticed it hardly ever in my house.

hmm... I tried this trick with ac1200 routers that do not have mesh support and all I got was a constant disconnection from the network and attempts to connect to more and more of these routers. In access point mode with the same password and Wi-Fi name. Homever, this failed.

In general, the possibility of backhaul should be indicated as one of the main advantages of easy mesh. I'm very disappointed in aix53(

  @BNTEK 

the real problem is TP-LINK wont tell you about this features you really need.

same model differs AX53 V2 should support ethernet backhaul, but why not AX53 V1?

when you buing it from store you dont see version V1 vs V2.

you dont know about payed features and so on. 

Very bad product definitino from TP-LINK, almost like scam.
