If a WiFi network has the ‘limited connectivity’ sign next to it, it means that you’re connected to the network but do not have access to the internet. The main reason for this issue is that the DHCP server is not responding. And when the DHCP server doesn’t respond the computer automatically assigns an IP address to itself because the DHCP server was unable to assign the IP address. Hence the ‘Limited or No connectivity’ error.
