Hardware: GL-MT6000
Firmware 4.7.0-op24
It's on 160MHz and it should be on DFS channel according to this information:
But it's in a Non-DFS channel (43)
And selecting 'Auto' should result in picking a channel with less interference, but it's choosing one that is already used by a neighbor
- GL-MT6000 (4.7.0-op24) is the red one.
- GL-MT3000 (4.7.0-op24) is the blue one.
- Neighbor is the coral colour.
By the way, GL-MT3000 seems to has +6dB stronger signal (double of power). They are in the same room, distant 30cm from each other.
