 That's what I'm going to go for.  I was just hoping for something else
 to do in the interim, like tweaking RTS/CTS values or something.
As Jack said earlier there can be many reasons for this. Is this a
residential area? Is the NF poor on both 2.4 and 5g and across the whole
band(s)?

Have you tried turning the radios to see if it's from a specific direction?

Yikes!

MT radios with the squelch function.
BIG antennas and JUST enough TX power to get your system 10 to 15 dB over 
the noise levels.

Cross polarize as much as you can.

Move one end?  Even if you have to make two or three hops, but pointing into 
a new direction might help.

Out of all of the 2.4 and 5 gig bands there must be somewhere that you can 
go that's not that high...

 When you have a noise floor of -30 dBm to -50dBm on a 2.4/5.8 11a/b GHz
 Wi-Fi band, is there anything configuration related that you can do to
 alleviate the problem other than switch channels, use narrower beam
 antennas, etc.

 (I've got a situation where I have to make chicken salad out of chicken
 crap for a little while until I have another option.)

Well, speaking as one of the most experienced wireless 
interference-reduction specialists in the broadband wireless industry 
(and also one of the most humble)...

No, there's not much you can do except possibly to deploy more access 
points (or wireless nodes) closer to your end-users. You will have to do 
this in a way that does not increase the level of inter-access point or 
inter-node interference.

My recommendation is to either a) call in an experienced wireless 
professional for advice, or b) ask the kid next door who knows 
wireless because he deployed a wireless router in his bedroom.
