Try going UNDER the trees.

That's pretty rare.  WiFi is designed to share spectrum with other similar 
systems.  If it were a non wifi system causing you grief it would likely be 
more consistant.

Only channels 1,6, and 11 are non overlapping with other.

Again, it can happen.  But it would not likely be so long at a time.

Don't.  Not for this short of a link.

If you insist on playing with an amp (that'll put you over the eirp rules 
for any channels above 5 or 6 as I reacall) look at shireen, teletronics or 
rf linx (or is it rf lynx?).  Hyperlink is a popular brand but they tend to 
sell people amps that put them outside of the FCC rules so I don't like 

Hope it helps,
