A:AnswerTime to leave Windows 7. You are having to pay for security and by now it is very compromised and slow.
I just bought a Chromebox for about $260 from Amazon that requires no security and it works with my large screen monitor. This new wireless printer was $130. It is a great though a little slow.
A:AnswerThis model only supports a 2.4 GHz WiFi connection. Most routers should be dual band and support both 2.4 and 5 GHz. You might check your router settings to make sure the 2.4 GHz network is not set to off.
A:AnswerI'd have the Geek Squad set it up if I were you. It needs coding on each device to be able to print from all the devices in your home (or the location of the printer.)
