My Prism won't connect to any wifi

[AC Question]

I have a Prism. I have no idea how old it is. I am trying to connect to wifi, but it wont pick up any signals. All of my devices here at home pick up my wifi signal, except this Prism, and I really need it to. How can I fix this problem?
Thank you.

Welcome to Android Central! The Prism can only access wireless 802.11b & g. Could it be that your home wifi router is set to 802.11n only?
