How do you do that?
Have a look through some of the other threads on here - there are loads of details on how to do those things.
You can even try the Apple 'Airport' app on your phone to scan the Wi-Fi channels and see if a neighbour is interfering on the same channels (turn on scanning in the phone settings for that app, then off when finished).

I know a bit about Wi-Fi, Telecoms, and TV as I used to do it for a living but I'm not perfect so don't beat me up... If you make things you make mistakes!
