This should now be possible on quite a few of the supported radio models: Mikrotik hAP ac lite / ac2 / ac3 as well as the GL.iNet AR750 / 750S.

Good thoughts. I removed both the _hwmode_ and _htmode_ options from /etc/config/wireless and rebooted. Same behavior with channel 6 not allowed and hostapd disabled. iw reg get for 2.4ghz =...

I just tested this again. All 2.4ghz LAN AP channels are usable **_EXCEPT_** for channel 6. Channel 6 is not available when using 2.4ghz LAN AP.

This is very easy to test. I'll test it again tomorrow after our family visitors are gone.

Channel 6 appears to be working when the 2.4ghz radio is configured as a LAN AP on my AR750. I now see it in the list of wifi APs on...

Agree... it was happening on 3.22.6.0 before the Spectral View was introduced. So the Spectral View only served to highlight the issue visually. This screenshot is from a node running...

IW scan results: [iw-scan.txt](https://github.com/aredn/aredn/files/8987432/iw-scan.txt) As mentioned above, other nodes scanning on 5mhz channel widths do **not** see channel -4 on this node -- they only list a channel -4 entry...

Since the WiFi Scan results are simply the web presentation of the `iw dev wlanX scan passive` command, the question of root cause seems to be “What is causing the...

Switching my 2.4ghz nodes to 10MHZ channel width also produces a bogus entry in the table for channel -1 as shown below. It should not be possible to have two...

@pmilazzo Paul reported last night that during his testing the root cause of the bogus scan table entries appeared to be related to collocated node proximity -- possibly receiver overloading....
