GL-AR750 WIFI issue TX 6Mbits only on 5GHz?

Hi folks
I have a brand new AR750 running stock Firmware 2.27 which I upgraded from 2.263 using the GUI immediately after undboxing.
I then immediately installed Wireguard which is running better than I expected.

To get into the router I go straight into LEDE by going to http://192.168.X.X/cgi-bin/luci/admin (therefore completely bypassing the stock GUI).

Heres my problem:
Under WIRELESS OVERVIEW (http://192.168.X.X/cgi-bin/luci/admin/network/wireless)
Generic MAC80211 802.11nac (radio0)
Channel: 48 (5.240 GHz) | Bitrate: 6 Mbit/s
71% SSID: XXXX | Mode: Mast

Under ASSOCIATED STATIONS
RX Rate / TX Rate
-60 / -102 dBm
400.0 Mbit/s, 40MHz, VHT-MCS 9, VHT-NSS 2, Short GI
6.0 Mbit/s, 20MHz

What’s ging on please??

When I run internet speed test I get 20Mbps on a 50Mbps line and streaming HD is absolutely fine… my wifi is set to my country standard and the AR750 is only 5gHZ signal on the channel.

So you mean that the real speed is 20Mbps and it is fine, right?

The Bitrate is the real bitrate and it may change, isn’t it?

Yes it seems the real speed is fine but the bitrate seems fixed at 6 for Tx?

If you look at below pic.
the top line is for 5GHz and bottom line is for 2.4GHz

Maybe it’s known bug of ath10k driver as mentioned on linux wireless

“tx rate is reported as 6mbps due to firmware limitation (no tx rate information in tx completions); instead see /sys/kernel/debug/ieee80211/phyX/ath10k/fw_stats”
