Your miner might not be seeing the internet.

If you have a Dlink router like me, edit your WAN to

Protocol:  Static Address
IP4: 192.168.0.250
IPv4 netmask : 255.255.255.0
IPv4 Gateway 192.168.0.1
IPv4 Broadcast: blank
Custom DNS servers: 8.8.8.8

Save and apply.
Reboot, with a direct ethernet connection from Ant to router or switch

If this works, you can access your Ant via a computer on your network by directing your browser to 192.168.0.250
