Techdata: TP-Link TL-MR3420 v3

This device is NOT RECOMMENDED for future use with OpenWrt due to low flash/ram.
DO NOT BUY DEVICES WITH 4MB FLASH / 32MB RAM if you intend to flash an up-to-date and secure OpenWrt version onto it! See 4/32 warning for details.

1) This device does not have sufficient resources (flash and/or RAM) to provide secure and reliable operation.
This means that even setting a password or changing simple network settings might not be possible any more, rendering the device effectively useless. See OpenWrt on 4/32 devices what you can do now.

2) OpenWrt support for this device has ended in 2022.
19.07.10 was the last official build for 4/32 devices.

The development branch can contain experimental code that is under active development and should not be used for production environments. Snapshot images may support additional hardware; however, it is experimental, considered unstable, and sometimes won't compile.

Prebuilt snapshot images do not come with any web interface or GUI. You will need to be comfortable using a command line and remote shell to install one yourself → How to install LuCI
