Which is better for the RPi 4B on these weather systems when the device is outside and the Pi is housed inside a plastic box?

2.4GHz propagates better. But either will work unless you are in a marginal area.

That's what I thought. Do you know an easy way to set a Pi 4 to use only 2.4? I haven't been able to find anything on the web that is straight forward.
My Pi wants to pick up the 5 Ghz all the time.

Are you setting the preferred network using the wpa_supplicant file?
Thanks,

Are you setting the preferred network using the wpa_supplicant file? Thanks, Jason This was my first thought. I tried to enter a country code that I thought had only the 2.4 GHz wave length, but on a reboot I can't seem to access the weather station via ssh/vnc. Does on need to place the actual wave length in the wpa_suplicant.conf file? Like this: network={ ssid="Your_AP" psk="Your_Passphrase" freq_list=2412 2437 2462 }

I have not but my 2.4 and 5 WiFi networks are separate ssid's on my router. Here's what mine looks like:
country=US update_config=1 ctrl_interface=/var/run/wpa_supplicant
network={ scan_ssid=0 ssid="TOP-PRIORITY-SSID" psk="password" priority=1 id_str="Home" }
network={ scan_ssid=0 ssid="NEXT-PRIORITY-SSID" psk="password" priority=2 id_str="Home" } Hopefully this helps.
Thanks,
Jason
