What is your local IP address? You need to set your IP to something in that subnet
Set your IP to 192.168.1.98
Subnet 255.255.255.0
Gateway can be blank
then hit 192.168.1.99 with browser.
Login to Ant with root:root
Go to Network - > Interfaces -> Wan -> Edit
Change WAN settings to local network - Whatever your PC or router is assigning for DHCP/Static.
Change S1 static IP to something outside of your local DHCP range.
Example
192.168.0.150
255.255.255.0
192.168.0.1 - Gateway - Your router address
DNS - 208.67.222.222 - 8.8.8.8 - 192.168.0.1
Reboot S1 unplug cable from Ant. Plug ant into network and change your PC IP settings back to what they were.
Hit S1 with new WAN ip you assigned on local network.
Does that even make sense? lol
If not just tell us your local network IP then we can give you exact addressing.
