TP-Link Archer A7 v5.8 supports OpenWRT?

@tejas77 

Hello, it is actually not suggested implementing a third-party software into the Archer A7, which will void the warranty, and we will no longer provide the support for it.

However, if you do want to upgrade the openWRT firmware into your A7, you may search online to get some help, as we cannot provide any guidance on this. 

Meanwhile, below is the statement regarding the use of the 3rd party firmware:
