Well, I am new to the forum, I have been buying TP Link devices for over 5 years and I have noticed that the company gives 1 year support and 3 years warranty on its devices, according to the country, which is being sold. Being that it makes 3 updates per device as a rule during the period of 1 year, if I am not mistaken it was always so I hope it does not become a puppet because I modernized for 5 years, all my devices that were TL-MR3020 v1.0, 2 TL-WA854RE v2.0, 2 TL-MR6400 v.1.0, v2.0, Archer MR200 v4.0, RE450 v3.0, RE200 v4.0 and on the penultimate he was forced to buy the RE200 v4.0, because the RE450 v3 .0 lost support for what appears to be the mesh, I think it's a shame the company does not buy the year of support as in all other devices with a last firmware update supporting this device for a mesh, here is my discontent on of millions of people who may have purchased RE450 v3.0 and do not have support for a mesh.
For me it is shameful that I always liked TP Link.

@Winter49 Good, now you can see how Tp Link behaves, end of the Year One Mesh for some devices was gone, now have a glimpse of the initial page of One Mesh Support notice that some Devices are represented, by the small images that belong to some devices that should receive the desired One Mesh, be ashamed Tp Link, see the attachment as proof of the Support page and the date of the Print Screen
