@ShivaShankar Same wish here! I have a C80 and a new AX73. Really misunderstood the oneMesh thing and thought the (older) C80 could be a mesh station, linked to the AX73.

Hi, the specific mentioning of two router with OneMesh being compatible with each other I have not seen. But the advertisements tell "Combine one or more OneMesh devices to create.... etc.". This insinuates that ANY two devices can combine to create a mesh network. However, this is not the case as it turns out. The advertisement would be less false if it told you can add an RE device to a router, and if they both support OneMesh it will be able to create a seamless experience (including roaming and what not...).

cheers

Please see this webpage below (in polish language sorry ;)

What you can see here, is a one mesh Network, with many devices (including many routers) with statement, that you can have it all working.

It's misleading.

I also bought tplink router (2nd one) assuming I can create onemesh with the old one (one mesh compatibile). I was so surprised, that I cannot create, what is shown on this picture. And it seems I'm not the only one :-/

I could understand, if you would have 1 router and many repeaters there... but you have many routers there.

It is not ok the way you are advertising this feature. It is misleading and if someone sues you, it can easily win it, at least in Europe.

I bought two routers because where I could place the access point I also need a cable connection and wanted to avoid adding a switch. 
Please add this basic feature. 
Thanks.

Yes Kevin from TP-Link there are a couple blatant misleading pictures and statements that show that another TP-Link router can be used as a mesh member.

The images all over the onemesh page to this day still depict multiple routers with other routers and extenders swirling around each other.

Plus there is text that states:

"Without replacing your existing devices or buying a whole new Wi-Fi ecosystem, OneMesh™ helps you create a more flexible and cost-effective network that covers your entire home with TP-Link’s OneMesh™ products."

which is misleading as it states "onemesh products" of which a onemesh router is a part of. Yah it's been modified now to add in some areas of the body and the faq that it's only extenders and power line devices that can be added as mesh members but the very first quoted sentence which shows up at the very first line of the onemesh description site is still misinformation, borderline disinformation.

Also stop wasting all ur time trying to find all the descriptions and articles and change them and instead spend that energy just fixing the problem by modifying the protocol software, which really would not be that difficult.

This is even worse and more misleading than the whole long distance wi-fi CPE710 issue where they r the only product in the pharos  line that do not support the maxtream TDMA option and it's not listed anywhere in the product discriotion or included documentation except for one obscure piece of product literature that no one would ever download from the support website.

Your customers are screaming out to u TP-Link all over this thread and multiple other threads and even other forums, just add the ability for wired backhaul and allow routers to be used as mesh members in onemesh! Listen to what ur customers are saying!

Problem solved.

  @Kevin_Z Like many, it would be great to setup two routers in mesh. I did run across a tp-link produced video on youTube that doesn't specifically say that two routers method isn't currently offered. https://www.youtube.com/watch?v=8DvY9TDiRWs 

Thanks Ken

i bought a AX6600 and 2 units ax1800 because i saw tp link website says one mesh system in all one mesh devices. when i click on the one devices, one would automatically thinks that all devices in compatible to have one mesh system to each other. In the Q&A, no such question is post. now i wasted so much money on the routers and lose confidence in tp link. Going to switch to ASUS from now on.
