i had to abandon going to one of my customers any more as it was getting silly (most plug in power packs kick out more EMI then wifi does, also O2 mobile mast about 300-400 meters away)
god knows what happened when local council installed solar panels on there roof (going to have to walk past and see if it has solar panels on it not that he has much choice as he does not own the flat and the meter is on the outside in a cupboard)
Biting the hand that feeds IT
