@Abhi093 Hi Abhi, Pls see the below photo as requested. My Airtel BTS tower is almost 400 meters away.

@cbzvenki @Abhi093  Hi I am not sure about the internal PCI-E modem model they are using in MR600, Actually, Qualcomm X12 modem has CAT12 with 3XCA combination mode support with 600 mbps download speed with MIMO 4X4 capabilities.

But on TP-Link website, MR-600 specification mentions that it as a CAT6 device not CAT12, and the first post about the beta firmware description says it has only 2XCA combination mode support which will technically go a maximum of 300 mbps download speed.

If TP-Link uses the CAT12 modem inside MR-600, then the cost would be much higher than the current market price. We can check by opening the MR-600 router but the warranty will void.

@Rajiv.R Very useful information. 

Just wanted to check if you recommend some good antenna for the MR600 in India, am from chennai and searching for good Antenna in ali express am not sure if i will get them shipped to India. can any one share a link which i can use to purchase in India which will support our router.

@Abhi093 Thank you so much. i do get good signal, Airtel has in band 3 and Band 40 at close to 13 to 15SNIR value and vodafone at 7 SNIR. Let me check LPDA. Thank you so much. Eagerly waiting for TP Link to release the official Firmware with band select option. 

@darant I purchased the LPDA antenna from Inda Mart seller RF solutions. They courierd to my location the price is around  Rs 650 for 12 dBi antenna.

Cheers,

Venky

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.
