RE450 v3 - DFS false positive on 5GHz ch. 64
I'm desperately trying to set my RE450 (AP/bridge mode, latest available firmware) 5GHz radio to channel 64 (band 2/DFS), 80MHz.
It will systematically bug out to channel 34, possibly because of a DFS radar scan false positive. Channel 34 is extremely busy in my neighbourhood, so less than ideal in terms of interferences/performance.
I'm saying false positive because I have another AP (different make) in the same room that will stay on channel 64 without bugging out, while having the same DFS requirements.
I'm a bit stuck there, short of trying the OpenWRT route, which I would prefer avoiding.
Thanks for any help!
