I'm trying to connect my old raspberry pi 2 magic mirror to the new wifi6 router, but I'm having a world of trouble doing so. Currently, it can only connect to the old router. If I scan, I see the old and new router (Typhon & Hermes respectfully). I've done all the standard stuff with wpa_supplicant.conf to store the SSID and password, but it just will not connect to the new router (other devices do though, with of course the same SSID & password). I've changed my wpa_supplicant.conf back and forth to have my old router and then replaced those entries with my new router and it only ever works with the old router's info in there. Below is a console output in which I have given up trying to use wpa_supplicant and tried to use network-manager. I can see that with
iw dev wlan0 scan that I see my new router Hermes and the old router Typhon, however when using
nmcli d wifi connect Hermes, it is no longer seen. I'm very confused by this and any help or insight would be appreciated.
pi@raspberrypi:~$ sudo iw dev wlan0 scan | grep SSID
* SSID List
pi@raspberrypi:~$ nmcli d wifi connect Hermes password ***
Error: No network with SSID 'Hermes' found.
I'm currently using raspbian 10, buster.
