I have a Raspberry Pi Zero W that is connected to my router over a wireless connection. I initially had trouble connecting because I use the same SSID for both the 2.4 and the 5GHz band, so other clients in my network can choose which band to use based on signal strength.
In order to get my Raspi to connect I changed the SSID of the 2.4 GHz band to “NAME-2.4” in order to make sure the Raspi could distinguish between the two bands. It seemed impossible to get the Raspi to connect to my router when both bands had the same name, I’m not sure why. This is especially weird because the Raspi zero W is only equiped with a 2.4GHz antenna.
Is there any way I can make my Raspi distinguish between the two different networks if I go back to the situation where I give them both the same name? Perhaps by “hardcoding” the MAC address of the 2.4 GHz antenna in the wpa_supplicant.conf, or someway via SSH, assuming that I can still connect to the device somehow.
