Another interesting thing to test is compliance with WiFi standards. We had a situation where our devices were crashing the customers APs and they blamed our radios but it turned out it was because our devices and antennas were weaker and more mobile so they ended up disassociating and reassociating a lot, which sometimes confused the WPA layer in the AP and caused it to crash. We had to show that their existing clients were doing it too when you moved them to the perimeter of the coverage area. In the end the AP vendor had to supply new FW but it was a long drawn out battle.
