We don't need Tp-link router, because Asus has got AiMesh is the same like one mesh but it can conect between routers 

  @kmaillster Yes. But what about existing Customers? This feature should have come out of the box but didn't and now causing major inconvinience for the buyers. TP link should really think about pushing this features as probably it's not held back by any hardware limitations, hopefully. I have 7-8 tp link devices in my house and this feature would really help them work together. Thanks

Any word when the "Coming Soon" Will buy, I already had a TP-Link Router that was not on the supported list, so I bought a third that was on the list only to find out it's not possible to one mesh between routers. Please fix this soon!

  @Kevin_Z Can you please update on this topic we are in 2022 and still no firmware update to support One-Mesh between two TP-Link OneMesh capable routers? This is dissapointing.

  @ftibor 

they won't do anything about it unless you do what I did. Call the credit card company and dispute the charge as false advertising or doesn't work as advertised. The bank will bill them back and once they are penalized enough to start caring, they will fix it.

Hi.

This is requested more than 2 years and TP Link answer as not yet which mean we are working with. 

Now years 2022 and sti say comming soon.  Most of other brand already support with multi router with mesh network. What TP Link do it, are you just enjoy your house during pandemic. Support fast

  @ftibor I just bought msyelf 2 OneMesh AX3000 ( AX55) routers - I can confirm they cannot even persist properly in the same network - admin module cannot be loaded and keeps asking for a password when set in the same network -  nowhere it was mentioned clearly on the box that they would not work together in a OneMesh network - a lot of money wasted :-( 

This is very sad - I used to be very fond of tp-link.... 

The shop won't even take them back because the boxes are opened and the device is not "broken"... but for me this does not do what I would expect it to do :(

You could at least mention this on the box I think... buying to OneMesh devices that cannot work togehter without mention is counter intuitive to me.

  Pretty sure we have enough people here for a class-action.
