I've just had a brainwave about Electro magnetic interference.
Without giving your location away to the whole world (OK PPrune) does your location mean that you are close to sources of microwave transmissions like L band Radars from ships or shore bases (1 - 2 GHz) or DAB audio transmitters. A bit of a long shot but a maybe, DAB transmissions are a bit lower in frequency than 2 GHz Wifi
Or S bamd Microwave transmissions (typically 2-4 GHz) Often used for satellite communications.
Finally communications C band transmissions - (associated with TV receive only transmissions 4-8 GHz) - You may have quite simply, an accident of location that's very uncommon.
Another one: Is there a wireless transmission power setting available on your router - I use XP pro on my Dual boot Dell Vistro Win/Ubuntu and successfully reduced the transmitter power a little, ( 20 % reduction - XP ) to increase battery life
CAT III ( I'm no expert, needless to say)
I had FM radio interference from some traffic using Cambridge - You could hear the weather radar scanning patterns over the loud speakers - Older radars only I think.
