I have a Archer MR600 V1 purchased in July 2021.
I wonder how to navigate which firmware version is considered new, BETA of one type or BETA of another type?
And which BETA has the manual band selection that works and is the absolute latest "temporary" solution?
A few weeks ago I noticed this band choice problem and spent (literally) hours reading about this issue here of this forum. (not what I had planned!)
So I then went through the real trouble of installing this my current version (1.1.0 0.9.1 v0001.0 Build 201204 Rel.66940n).
The text "Build 201204" is the date correct? So December 4, 2020? So 10 months ago? I used the Utility tool and installed it.
It gave me the choice to choose bands manually. But it seems unstable (I have to reboot alot) and has that "confidential" message written sideways on the web interface.
Not so professional.
NOW when I look at the web interface on my device (http://tplinkmodem.net/) it says I can upgrade online to v (1.2.0 0.9.1 v0001.0 Build 200511 Rel.44954n)
Now that date: "Build 200511" seems to be May 11, 2020? That is 16 months ago! So this is an earlier OFFICIAL upgrade I am offered to do from a later BETA and that most likely does not include the manual band choice? Please answer...
BUT on the support page (https://www.tp-link.com/se/support/download/archer-mr600/v1/#Firmware)I can see a version called: Archer MR600(EU)_V1_210608 and Published Date: 2021-06-10 So this is what? A newer BETA? This was published 3-4 months ago? Does it include Manual band choice?
Listen, this is 100% unacceptable TP Link! No bad vibes on you personally who is answering us in this forum, but how on earth can a product
be sold and then your answer is "We don't know when the team will get around to fixing a proper firmware version that includes solution we have solved in a series of Betas but somehow can not place into a proper solution. Just check back here every Friday and hope for the best."?
Please! Right now, go Print out this LOOOOONG forum chat on paper, copy 15 copies, walk up or down to the office were these hackers sit
and demand that they deal with this issue!! This product is STILL BEING SOLD IN STORES!
I don't want to be unpolite but THIS CHAT HAS 59 KUDOS, 32796 VIEWS and 200 REPLIES!!! It should be your NO 1 Priority!!
