Alex has said it all. I had a quick look at the Mikrotec site the other day, and if I read it correctly, the 5Ghz channel used was way outside even the extended WiFi range. Therefore a computer would not even accidentally lock onto the channel used by the dish. Probably a mast mounted dish would be easier to fix, than drilling your stone walls. It need not be too high up, only enough to be clear of people or stray sheep blocking the xmission path. As far as your interstation traffic is concerned, fine having greater than 300 Mbs or more WiFi, it is nice to have, but do you really need it? One photo would take 6 times as long at say 50Mbs. That would mean your photo would take maybe 1 minute instead of 10 seconds. Would this time scale really matter to you? You were previously worried about WiFi congestion from your neighbour. By selecting a lower speed, the number of carriers your router is transmitting to carry your data is half the number a wider channel would be transmitting. So for the same transmit power, your signals are twice as strong ( +3db ). Also, if the routers DSP is carried out correctly, your received bandwidth would also be half as much as the wide bandwidth signal. Half the bandwidth means half the received noise ( 3db down ), meaning your WiFi signals appear 6db higher above the noise level than would otherwise have been. If your new neighbour goes wideband, you may still move your channels away from him, and also your signal in your home should be well above any potential interference. I hope my post makes sense, and also accurate logic............
