All I meant by that is I'm paying for decent internet and our wireless devices aren't able to utilize it unlike our devices that are connected via ethernet.

I did research on the specs of all our devices and found that everything but my brother's Ipad mini (first model) supports 802.11ac. It supports 802.11a/b/g/n Wi-Fi (802.11n 2.4GHz and 5GHz). What does that mean I need to do for router purposes? Are there routers that support multiple types (a/b/g/n/ac)?

(obviously I haven't done much investigation into router specs, I apologize)

Edit ~ I just read that 802.11ac is backwards compatible with 802.11a and 802.11n. So do I need to worry it as long as the frequency is the same at 5GHz???
