Access point mode on the FP4 ignores band setting

Hi, when creating a Wi-Fi hotspot on the FP4, the set band is ignored. If I set the band to 2.4GHz, the Access point is still operating in the 5GHz band, ignoring the setting.
To reproduce this, just create an access point with a band setting other than dual-band and then check on which channel the AP is operating.

As far as I remember is that because in some countries you are not allowed to run APs in the 5GHz band. @All Please correct me if that is wrong

Yes, regulatory domain is a concern when running an Access Point. I don’t know of any countries that prohibit 5GHz operation, however the restriction is, that devices can’t operate without performing an extensive DFS scan on the channel. Most consumer Wi-Fi devices have the 5GHz channels flagged as no IR (Initiate Radiation) so they will only begin transmitting, after they received a beacon from an access point, which indicates that the channel is clear. The problem here is, that the FP4 hotspot goes to either the 2.4GHz or 5GHz band, ignoring the setting completely. This is probably decided based on available airtime by the Wi-Fi driver and probably selects 5GHz more often, because the 2.4GHz band is an absolute war zone almost everywhere and has less channels.

I thought, it was using 2.4 GHz no matter what you chose in the settings However, I did not test this on my FP4. That would have been a “typical” SW solution for FP-OS in my opinion :wink:
