[Solved] Recommended wireless settings for GL-MT6000 (Flint 2)

Installing and Using OpenWrt
1

Hi,

I'd like to ask the MT6000 users in the OpenWrt community for your recommendations and opinions on the most optimal wireless settings (both available in LuCI and not) for this device.

It seems that MT6000 has gained considerable following among the users of this forum since its launch in Q4 last year. Wondering if there can there be a broad consensus regarding its optimal wireless settings?

Does not differ from any other Openwrt device.

edit: turns out background_radar prevents 5 GHz wifi to start after boot, so better to keep it disabled.

Add option 'background_radar' '1' to /etc/config/wireless 5 GHz radio. This will make it scan in the background for radar when DFS channels are in use. There's no 60 s wait on config change or reboot.

Otherwise there isn't anything special. If you want to get some feedback, just share your config here.

My current wireless settings are indeed nothing special:

        option type 'mac80211'
        option path 'platform/soc/18000000.wifi'
        option channel 'auto'
        option band '2g'
        option htmode 'HE40'
        option country 'EU'
        option cell_density '0'
        option txpower '17'

config wifi-iface 'default_radio0'
        option device 'radio0'

        option mode 'ap'
        option ssid 'SSID_lan'
        option encryption 'psk2'

        option network 'lan'

        option disabled '1'

WED is not enabled. I haven't looked into more advanced settings (DFS, beamforming ?, else?) - perhaps, there are some device-specific options worth using, like the background radar mentioned?

Currently on stable 23.05.4.

All good settings are automatically enabled.
Your country does not exist and remove power cap.

Great that you reduced the power to meet your actual coverage requirements.

I didn’t know country 'EU' is a thing. It doesn’t appear in my OpenWRT snapshot version in luci. Better set it to your actual country to ensure compliance.

Unless you live in a secluded area, don’t use 40 MHz channels in 2.4 GHz band. This causes interference for everybody else.

DFS turns on by itself when you set a 5 GHz channel that requires it. Don’t be afraid to use them, unless you’re close to a weather radar or an airport. Especially channels 100-128 are nice if you need more coverage because they allow for more power.

If you prefer the lower channels with 80 MHz width, consider using channel 36 to improve coordination between networks. Read the details why here: https://www.extremenetworks.com/resources/blogs/can-40-mhz-and-80-mhz-channels-co-exist-in-a-wi-fi-6e-world

Thanks a lot for the hints!

Apologies for the confusion with the country code. I redacted it, just to hint that the location is Europe.

Yes, tuned it down a bit (no exact science behind the step size) as a courtesy to my neighbours since the router is the centre of the living space and sufficiently covers it. Perhaps, I can go even lower with that. Haven't had a chance to experiment yet.
