I hear you loud and clear. The metal can idea only does so much so don't let any bozos on the net fool you into thinking otherwise. It can help under some circumstances where there is a lot of interference (other wireless band activity going on, and no it doesn't have to be on the same channel you're using to interfere). The real problem as I see it is the ever increasing reliance on the internet from everything that can be transmitted digitally. The amount of shit getting shoved into the pipes increases all the time and the available capacity of the `net can't keep up with it all. Couple that with the number of wireless devices for various uses increasing. They all use the same frequency band right now whether it's a cordless phone or a radio controlled dirigible toy.
