You decided to maximize security by using WPA$2$ for Wi$-$Fi security. Although this option requires much more processing power in order to run its security algorithms, occasionally causing network slowdowns, it's much safer.

You plan to post signs in the seating areas informing customers that, although your network is secure$,$ you recommend techniques they should use to keep their data and devices safe when using any Wi$-$Fi network.

You've already got a service contract with an Internet service provider $($ISP$)$ for the POS $($point of sale$)$ network the cash registers and inventory system will use. The representative from the ISP hears of your plans, and tells you that you can run the same line for the POS and the wireless network. You do some research before you get back to them with an answer. Will you use the same ISP for the guest network, or contract with a different ISP for the guest network?

Same ISP

Separate ISP
