Hello,
This router is fairly new and has Mediatek MT7621 chipset. It also has OpenWrt support on the stable channel. However, the open source WiFi driver(s) for mt76 apparently have an issue with the 5 GHz WiFi being unstable, and the performance being far inferior to stock firmware. Beamforming and MU-MIMO support is also absent in OpenWrt. This is also true for the snapshot builds of OpenWrt which apparently have a newer (open-source) WiFi driver.
I think other routers having the same chipset also suffer from these issues on OpenWrt, like Netgear R6350, Netgear R6850, D-Link DIR-878, etc.
With support for these Netgear routers just being added to the DD-WRT beta build from 02/15, it would be appreciated if we could also add support for TP-Link Archer A6 v3. Proprietary WiFi driver could really help this router.
Can I try enabling SSH on stock firmware through modified config backup file, as described in the link below for an earlier version of identical router, and making a fullflash dump through SSH?
I have this device (actyally a C6 v3.2 which has exaclty the same hardware as the A6 v3) with UART access. I'm able to both access U-Boot environment as well as the root console after stock firmware boot.
However I don't know how to perform this "fullflash dump". I searched on the internet but I was not able to find some clear instructions. The ones with U-Boot instructions had commands not supported by this U-Boot (see below).
Is there any wiki here at dd-wrt.com where I can find more documentation about this process?
Anyway, OpenWRT already supports this device, below is the partition structure of this device, not sure if this helps DD-WRT:
