In my case, it was set to Auto by default and sometimes it was getting connected and sometimes it was not. Now equipped with this knowledge, we need to go into the router page and select one of the enabled channels. This tells you what all channels your raspi is listening to. Wlan0 32 channels in total available frequencies : Note on Ubuntu Jammy for the Pi the command is sudo iw list instead. Ideally, this is supposed to solve the problem however, if you are still unable to see the 5Ghz SSID, you need to check what all channels are enabled by selecting your country by typing in the following command. You will need to go to Localisation Settings->WLAN Country and select your country. Most of the answers you will get on the internet will suggest setting the WIFI country.
Well, I searched everything trying to solve this and eventually realised the problem. I have commented a complete list of frequencies so you can select what frequencies you want to connect to. You may consider to move the freq_list inside the network block: ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=netdev This is an example for a general setting (use your settings for country, ssid and psk). # it limits the frequencies that will be scanned. # This can also be set on the outside of the network block. # set, scan results that do not match any of the specified frequencies are not # Space-separated list of frequencies in MHz to allow for selecting the BSS. # freq_list: Array of allowed frequencies According to the documentation in /usr/share/doc/wpa_supplicant/examples/wpa_nf you can set it general or within a network block: Just add a line freq_list= to /etc/wpa_supplicant/wpa_nf. If you find one then you can restrict wpa_supplicant only to connect with this frequency. It should give you at least one (ore more) outputs like this: freq: 5300Ĭapability: ESS Privacy SpectrumMgmt ShortSlotTime RadioMeasure (0x1511) rpi ~$ sudo iw wlan0 scan | grep -A5 'freq: 5' So first you should check if the 5 GHz band is seen by your RasPi. With my RasPis I have found that they tend to connect first to the 2.4 GHz band if both bands available.
