@Satheskumar I have one of these... LowcostMobile 4G LTE 5G Antenna MIMO 700/800/900/1800/2100/2600 Mhz 2x10m black cable LMR200 SMA Connector for Huawei B525, B593, E5186, B310, B315, B3000, Asus, TP Link, Dlink, ZTE .. https://www.amazon.co.uk/dp/B01E7CWNSI/ref=cm_sw_r_sm_apa_i_SZRJFb4XW33J5?_encoding=UTF8&psc=1

Actually 2 that I use for testing and normal use.

@Satheeshkumar you received V1 or V2 ? pls share. 

They made a bad MR600 v1. During warranty, if it has problems like frequent disconnections they should have to replace it vith a good v2! :(

I've installed the beta firmware and now I have the option to select both bands but when I did that the router still connects to only one band no matter which band I'm chosing.

Is it a known bug or I messed up something? Before I flashed this "beta" firmware I already upgraded to the latest official one and downgraded to this one, maybe that could be the problem?

@darant 

My router is the MR600(EU) V1.0 indeed...

But anyway, tp-link could release a non-beta firmware soon with this improvement..

Thanks for the support!

@darant 

Hi, one more question.

I've installed the this firmaware in my mr600(EU) v.10.

It is working. I can see the background changed to "... for test"

But I'm having a hard time to find where is the box that I can change the bands.

do you know it?

Sorry for my ignorance...

regards,

@darant 

I've been checking other posts, and I don´t have the Band selector.. Why? I've installed this beta-firmware that allows band selection..

@darant 

Sorry, I've precipitated my self. I rebboted the router...

I found the band selector.

thanks!

Hi all,

 

Following the long thread on the same subject discssing the BETA FW, as I said I would, TPLink have given me permission to share the FW download llink.

 

From TPLink - We recently released a beta firmware for Archer MR600(EU) V1 which can allow us to select 4G+bands for Archer MR600 manually.

https://static.tp-link.com/2020/202004/20200420/Archer_MR600v1_1.1.0_0.9.1_[200417-rel75138]_up_boot_2020-04-20_08.44.31.zip

For Archer MR600, if you want to use its 4G+network, your SIM card should support the CA bands group Archer MR400 supports. Please check the attached picture and check if your SIM card supports the band groups on the list or not.

 

They asked me to state that, this BETA FW is for the Archer MR600(EU) V1 ONLY!

 

Neither TPLink nor me take any respnsbility if you flash a none-EU router.

Hi, in advances, wireless, wireless settings, have you try to disable Smart Connect? (a small switch on the top).
