Slow Wi-Fi After Fresh Install

Installing and Using OpenWrt
1

First time using OpenWrt. I had installed OpenWrt 23.05.5 on GL.iNet GL-MT6000 (Flint 2) following the instructions and enabled SSID, however Wi-Fi's speed is only 30 Mbit/s while LAN is full 1000 Mbit/s. Did I need to configure something to get the proper Wi-Fi speed? Before installing OpenWrt, the Wi-Fi speed was 800 Mbit/s.

Please post /etc/config/wireless file (passwords and IP and 6-part MAC addresses edited out) and ubus call system board output.
wifi should be in range of gigabit with 2-antenna clients like laptops or modern or expensive phones.

Have to set your country, or the wifi will be slow.

From the speed I suspect you disabled WMM and are using 20Mhz channels and wifi-G speed. Check that via https://github.com/VREMSoftwareDevelopment/WiFiAnalyzer or Ubiquiti Wifiman - either should indicate wifi6 in action.

Attaching the wireless file.
ubus call system:

        "kernel": "5.15.167",
        "hostname": "OpenWrt",
        "system": "ARMv8 Processor rev 4",
        "model": "GL.iNet GL-MT6000",
        "board_name": "glinet,gl-mt6000",
        "rootfs_type": "squashfs",
        "release": {

The installation article said that Prior to enabling each SSID, your country code must be set so, I did set it. Is it possible to enable SSDI without setting country code?

Yes, it is possible, but 5GHz will be max 80MHz and ch36 only and you dont get ch12-13 in 2.4ghz

Show the first tab too.

Make sure that checkbox is set:

Here it is

WMM Mode is enabled. I wouldn't change anything from default.

bitrate + signal indicates you have 1-antenna wifi4 client connected (30Mbps on that)
Gigabit(s) is for wifi6 clients in 5ghz band. Make sure both AP-s have same name/passwords so that capable clients get best speeds. EDIT: yes, also same country code :wink:

I didn't realize I had radio0 with 802.11ax/b/g/n and radio1 with 802.11ac/ax/n. I've enabled radio1 and now getting proper speed. Thank you! 30 Mbit/s for 802.11ax/b/g/n threw me off, that speed seemed impossibly slow and made me think I needed to configure something else.
