Gloria wants to cut her phone service and use Ooma. Is that a good idea? Leo says that with one computer plugged into the internet, she can, but she'll also need a router so she can give access to others. A simple wireless router from Asus or DLink would work well. She should go for the dual band or tri band router. The WireCutter suggests the TP-Link Archer C7 (v2). She can find out more about it at thewirecutter.com.
Gloria should remember that when the power goes out, she won't have a phone because she won't have internet. That also means no 911. A cell phone is always wise.
