One of the first things I would do is a Wifi site survey, to look for conflicts between access points/channels, etc. Two recommendations for tools:

MacOSX: WiFi Explorer from Adrian Granados - US$4.99 from the Mac App Store. http://www.adriangranados.com/apps/wifi-explorer
Android: WiFi Analyzer from farproc - Donationware from the Android store. https://sites.google.com/site/farproc/wifi-analyzer
