So tried sudo ip link wlan0 up it did not connect to wifi but, was able to scan wlan0. Wlan0 Interface doesn't support scanning : Network is down When using raspi-config I get the message "could not communicate with wpa_supplicant." So how else can I enable wifi? $ sudo iwlist wlan0 scan The gui has a double red x icon and I get "dhcpcd not running" when you hover on it and nothing to select when you try clicking it.

#WXTOIMG UPGRADE ON RASPBERRY PI UPGRADE#
No problems on the update but some errors on upgrade, so I did sudo apt upgrade -f. I used sudo apt update then sudo apt upgrade. Used rasp-config to set local and changed the password, rebooted everything fine wifi came up. I had to add wpa_nf to the boot so it would connect to wifi on startup. I followed all the setup guides and have a 4" touchscreen with a case.
