Adding OpenWrt support for Xiaomi "Redmi Router AX6S"/"Xiaomi Router AX3200"

[dsouza]

I am having 802.11ax performance issues across a wall (AX6S). Within the same room 802.11ax performance is excellent, but in adjacent room and across a brick wall 802.11ax sometimes is barely usable, while 802.11ac has top performance (unexpected from my standpoint).

[Solved] 802.11ax worse than 802.11ac with mt76 driver?

I just upgraded one of my access points from an Archer C6 v3.2 to a Redmi AX6S. Since the new device has support to 802.11ax on the 5Ghz band, I`ve decided to do some tests. While in the same room 802.11ax has a higher throughput than 802.11ac (tested with iPerf3 on a wired Linux machine and and iPhone 13Pro), the performance of 802.11ax in another room across one brick wall is much worse than 802.11ac (see results below). I had the assumption that 802.11ax would always have a superior perfor…

Thanks!
