Good thing I haven't updated anything yet. :) Can you guys also add
3652.5 and 3697.5 back to the 3.6 default frequencies list? Also, the
upstream direction in the filter config used to be on by default and is
not now on 14.1.1. Would be nice if it was restored because I'm sure the
guys won't catch that's it's off now.

Well, I must correct myself! While there is an integrated patch antenna, its
gain is part of the 25dBi total gain, not in addition to, so you are correct,
we are off by 9-10 dB and are too low. This explains the questions raised at
Wispapalooza and what you are seeing here. The good news is that this is
fixable via SW and we will obviously get this fixed ASAP. I'll let you know
when we have an Open Beta load for you to use, it should be within a day or so
here, and we will expedite a formal released load fixing this.

Darren -
We'll take a look but the external gain for 450D is locked because that is the
property of the HW with the attached dish and radome. This is not changeable
intentionally.
The internal HW of the 450d is actually an integrated 450SM in a new housing, so
there actually is some internal gain via the 9dBi patch antenna, so that would
account for the difference. So TxPower + internal patch gain + external dish gain
<= EIRP would mean -4 is our max TxPower for 5.4 FCC to stay <= 30 dB EIRP.
However, we will take a look - there was some feedback at Wispapalooza that some customers were having issues installing these in 5.4G band, but the tx power should be correct.

Aaron,
I had a question about a change Cambium implemented on the 450D radios,
although it's not new to 14.1.1 (I think it started in 13.4): the Power Control
section on the Configuration -> Radio, External Gain setting is no longer
adjustable, and is locked in at 25dB. OK, but the radio seems to be thinking it's
got some sort of additional gain, because it won't transmit higher than -5dB
(reported in Link Status). Shouldn't the EIRP in the DFS band be 30dB, so it could
transmit as high as 5 dB? This seems to be causing a major connectivity issue in
the 5.4 band, but not in the 5.7 band, where transmit power is reported as
anywhere from 16 to 22dB on the same SM to the same test AP.
Why the disparity? Is there any hope for using 5.4 GHz frequencies on a 450D SM
to a tower you could not hit with a football?
