 I tried this beta version on newly purchase archer mr400 (ac1200) in btw upgrading my device the power shut down and my upgrade process stuck and my device got fully dead thanks to amazon's 7 days replacement policy so I replaced my device with another. 

So do it at risk if the product is under warranty or you are lucky like me.

Is this beta working or not I don't know if it really works in archer mr400 so reply to me asap.

I also want to try this beta but I don't be fooled?

Any news regarding band selection in the official firmware for the MR600v1?

@Kevin_Z 

@TP-Link 

Hi guys! I am jumping on board here to also ask when the official firmware update

that includes the band choice option for MR600 v1will be released?

I have installed the beta and tested different band combinations and 

it just seems pretty natural that this function should be part of the normal

firmware update. Note: this thread started like almost 2 years ago! 

I bought my MR600 v1 here in Sweden in July of this year (8 weeks ago).

@Kevin_Z 

I think that is more easy to humans go to Mars than you release an official firmware.

If I take so many time to release a firmware my boss fired me in a few weeks....

Hi, I have installed Beta version not V4 I have installed it  on mr6400 V5 , it's worked good, but some little delay in network recognizaition, and I think net speed is a little slower than the stable version. But I think it was good and you can just do some simple fix to it to work like as stable version as lasted fremware for mr6400 v5, just fix this problem, when I locked network to 3g mode, band selection option will disappeard, band selection just was available for 4g not for 3g, please add this option for both 4g and 3g, I need band selection for 3g too, I installed lastest stable framware again, please do that simple fix to beta version and release the stable version of band selection in two 3g and 4g mode as soon as possible, we are waiting for that. Thanks 👍

Any update for manual band selection in the MR600v1 official firmware?

@Kevin_Z 

Tried updating my MR400(EU) ver 3.0 with the beta firmware to get manual band selection, but the update ends with an error 4503 "The uploaded file was not accepted".

My current firmware is 1.16.0 0.9.1 v0001.0 Build 200414 Rel.62997n, and I have absolutely no idea why I have installed it and where I got it from. Maybe the beta firmware can't be installed on top of current firmware, because the version number is lower?

Is there anything I can do, as I truly need the manual band selection as sometimes the MR400 chooses a slower and weaker band from a more distant tower.

@kernash Never......

The router is almost obsolete and nothing about a new official firmware with band selection.

It was my first router from TP Link and will be the last, I never saw so very bad support, it´s a shame.

Well, they released a new firmware for the MR600v1 just 2 months ago, but somehow "forgot" the band selection feature.

TP link has promised for over a year to implement the feature. Now it is too late to return it to the shop and get a refund. Or have it replaced with a v2.

The beta versions are outdated and there are 3 different betas to fix 3 different problems, but no version to fix all problems.

So i'll keep asking until someone from TP-link makes an actual statement (instead of promises and excuses) about the situation with the MR600v1.
