I've also had some luck in moving the antennas. Should have mentioned that
before. I had one customer get 3 or 4 x the speeds just by moving his
antenna UP by 2'. Had another one double the speeds by moving it DOWN 4'.

Jim,
I have run into very similar situations, where high power lines, were the
only explanation as to the interference. I was able to work around it in
some situations by adjusting the customer antenna to shoot under the
powerlines, however, this is not always possible, nor is it always the
fix. In most of these cases, we were able to get data through, but not at
the speed that it should have been, so we would end up selling the
customer a lower speed package. I have been unable to find much
information about this, but would be greatly interested in hearing what
others have done, if they have run into it at all.

I hate to ask this question, but I'm at my wit's end with this one.
I recently installed a new customer (2.4 GHz) with a clear LOS to my
tower. The distance is less than a mile and I get -56 dBm of signal
strength. I've run a spectrum analyzer and it's dead silent when the
radio's off.. All sounds great! A real simple install, but the radio
intermittently locks up, fails to associate and most recently, simply
fails to work for more then 10 - 30 seconds at a time following a POR.
I've replaced radio (Tranzeo SL2) and gone to the latest version of
firmware. I even contacted Tranzeo Tech Support and follwed their
recommendations for timing settings. The only difference between this
client and all the others on my tower is that there is a power line in
the LOS path. Has anyone else found this to be a problem? It's almost
like an invisible concrete wall is between the AP and the site.
Thanks, Jim....
