WAN ip and LAN ip are in the same subnet
I am trying to setup a network but getting "WAN ip and LAN ip are in the same subnet".
Here is how it looks:
1. ISP Ubiquity antenna used to have DCHP enabled, but I have asked them to disabled, to have my own DHCP server on my TP Link router. I don't have access to management page of tha ISP antenna, but I know it has IP address of 192.168.10.1
2. I have TP Link router which support Access Point but once I want to change LAN IP to 192.168.10.2 it shows me error "WAN ip and LAN ip are in the same subnet". ISP antenna is connected to my TP Link router to WAN port. TP Link should server DHCP addresses.
I appreciate any help, how should I configure TP Link router.
Thanks
