Hello, We've found that our devices can't seem to operate on certain frequencies (e.g. 5660MHz) being used by access points like the Apple Airport Extreme and Asus RT-AC68U. I did a git bisect and found that 31dc1c5eca29d039ac8f26340defe44bd7e497c1 removed that band amongst others. A more recent [1] FCC source implies that these frequencies should be usable with DFS. Does anyone know the source for the commit that removed these frequencies from? Below is a patch that adds back these frequencies: ------------------------------------------------------------------------------------- wireless-regdb: Add back regulatory rules for US The FCC approved UNII devices operating in the 5470 - 5725MHz range with radar detection and DFS capabilities. See the [1] source for details.
