[General Maximus]

I would pm the mod back and thank him for his efforts, at least he is trying to do something about it. I would politely point out that you have noticed several other users in your immediate area reporting the same problem (give him the links to the other threads) and that you don't think the fault is to do with your equipment/cabling.

With these things it always about getting the right info to the right people and if you can help him connect the dots then hopefully either he or the area manager can get it looked in to pronto.
