Regarding Q31,

" u( _% P) Y  H2 OThere are a wide variety of devices that can cause interference on your 802.11 wireless network. If you suspect that your network is experiencing interference from other sources, look for items on this list as possible suspects.

Zigbee - Wireless personal area network technology
: }; x5 n% P9 r* [  YFluorescent lights NOT LED light!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
WiMAX
Other 802.11 networks - this is known as co-channel and adjacent channel interference. Since other 802.11 devices follow the same protocol, they tend to work cooperatively – i.e. two access points (APs) on the same channel will share the capacity of the channel.
Bad electrical connections can also cause broad RF spectrum emissions
Here are some devices that interfere with 5 GHz radios:
