Need location verified by 3 wi fi's?

You need to use 3 separate ISP connections, not just 3 separate WiFi signals. Depending on what device you are playing from, then Ethernet should work just as well.

When you connect to the Internet, the the game site gets the public IP address that you are using. This is related to the ISP to which the address range has been assigned by the Internet authorities. The ISP, and consequently the poker site, cannot actually tell how you are connected to the ISP (Ethernet, WiFi or even USB). They will be looking for 3 IP addresses assigned to 3 different ISPs all in New Jersey.

Changing your router or adding a WiFi extender does not change the IP address range you are using. If your neighbour has the same ISP as you do, then even that may not work as the IP addresses will still point back to the same ISP and as most people have public IP addresses that are not fixed but allocated from a particular block of addresses, it will appear that you are still using the same connection but with a new address assigned by the ISP.

Besides your own ISP connection, find a couple of other different ISPs you can use to make up your three.

1. That's one of the strangest things I've ever heard.

2. Three different Wi-Fi's means you need to go to 3 different locations and use their Wi-Fi network. Like McDonald's, Starbucks, and your house. It doesn't mean install 3 Wi-Fi broadcasters in your house.
