and time to time I see how 2.4 network work on 13th channel, and arp proxyng stop working, after manual reboot (restart wireless doesn’t help) - proxying work, but channel can still leave above 10
Is this issue can be walktrought or I miss some solution?
The stock firmware on the Flint 2 uses a closed-source wireless driver provided by the MTK SDK, which does not support the channels configuration option.
You may want to consider using OpenWRT 24 maintained by us with the GL UI and open-source wireless drivers, or a vanilla OpenWRT build instead.
It should be completely unsupported.
However, since the channel setting is currently set to auto, it will automatically switch between channels 1–13 (depending on the configured country code).
