Solution 464XLAT Support on TP-Link 4G/5G routers for Jio/EE/Optus/Vodafone and other SIM carriers
This Article Applies to:
TP-Link 4G/5G routers
Background:
With More and more SIM service providers gradually implementing 464XLAT mechanism in their services, after inserting the SIM card into TP-Link 4G/5G routers, some users might report that there is no internet access or certain Apps/websites can't be accessed. When checking the internet status, the router obtains an IPv6 address without an IPv4 address.
Available Solution:
The following beta versions have introduced 464XLAT support. It is suggested to install the specific version and check whether the reported issue can be fixed.
***Before downloading and updating the following beta firmware, please verify the model number and hardware version on the product label, especially the models with x.0, x.20, and x.30 versions. Please note that the x.0, x.20, and x.30 are different versions and are unable to use the same firmware.

Hi, based on other user feedbacks, if the Jio SIM is 4G and never used on 5G phone or updated to 5G, it should still work.
Besides, the latest beta firmware for MR600 V2 has already resolved the 5G Jio SIM issue, so please don't worry.

Hi, may I know the firmware version of your MR600 V2? the latest beta firmware for MR600 V2 should work for both Jio and also other ISP SIMs, please make sure the APN profile has changed to Airtel profile after you insert Airtel SIM.
If Airtel SIM still doesn't work, please share with us screenshots of Advanced->Status page and Advanced->Network->Internet page along with system log file.

MR600 v3 Beta version 230506 not working wifi and lan please New update
Hi, may I know if you are using Jio SIM or other SIMs? It might not work properly with other SIMs and we will update a new firmware to solve other SIM issue.
However, Jio SIM should work on the MR600 V3 beta version 230506, if it doesn't work, please share with us screenshots of Advanced->Status page, Advanced->Network->Internet page along with system log file.
Please also make sure the same SIM works fine on other 4G devices.

Airtel sim doesnt work at all. Not that "it might not work properly".
I am not asking for beta software that works with both Jio and airtel.
There is no ETA of new beta and i cannot wait till it is available as I need it for WFH.
All I am asking for is stock firmware that works with other carriers( Software that came with the router when bought)!!
It is available for other variants like V2 etc and why can it not be shared here?
I can understand t not sharing the stock firmware only when security is compromised!

Hi, MR600 V3 stock firmware is available on global site: Firmware Download for Archer MR600 V3, we will contact India local team about the India site.
However, I am afraid the Airtel still doesn't work after you installing back the stock firmware, and new beta firmware for MR600 V3 is expected to be available this week. I will share it with you as soon as possible once I get it.
