Best/fastest modem/router for Ipad and general computer use?

If you have neighbours nearby with wireless networks changing channel can make a big difference.

What are the speedtest.net results for your wired connection verses your wifi on your iPad?

If your running windows can I recommend inSSIDer a free wireless scanning app:
inSSIDer Wi-Fi Scanner | MetaGeek

Great for analysing local net activity, interference, channels etc..

I have an iPhone scanner on my iPad but believe most of them have been removed by Apple as they use custom APIs.
