I have confirmed the gateway, by checking /etc/dhcpcd.conf and ensuring entries for STATIC_IP, GATEWAY, and DNS are added to wlan0, as below:
interface wlan0
static ip_address=192.168.1.182/24
static routers=192.168.1.1.
static domain_name_servers=8.8.8.8
I’m however not sure if that is correct. Should I not rather have entries for wlan0 in /etc/network/interfaces?
