We just got the antennas tuned for a SR9 link between two spots.
We're running roughly -71/-69 for signal strength, with a -81 noise floor, in the 10mhz band. I've got 5-6Mbit through when bandwidth testing.
However, as soon as I start to flow "real" traffic through it, the link gets glitchy, ping times go up from 3-5ms to 300-800ms, and it starts disassociating, with excessive data loss given as the reason.
We also have a Trango 900 link that's started doing something similar - ping times going way up & generally being very unhappy.
Does this sound like interference? And how would I go about eliminating it - would an antenna stack help on the non-stacked end?

No visual contact, but a Trango link was reasonably happy on it until recently, when it started glitching out - which is why I'm suspecting interference.Do you have visual contact?
What is the distance of the link?
To you have full tx-power?
Try to change channel
Range is 3.5mi or so, tx power is set to full, and it's running on the clearest channel we can find (the Trangos do have a good frequency scan).

I saw this exact problem yesterday when I installed an SR9 30 feet from a live Trango client facing 90 degrees to my new SR9unit. My SNR was 21 but it would lose connections under load. I unplugged the Trango and the problem went away. I suspect if I had been able to move the channel of the Trango more than 5 MHz away from the SR9 the problem might not have existed. Now the Trango is permanently removed and things have gone back to working great.a Trango link was reasonably happy on it until recently, when it started glitching out - which is why I'm suspecting interference.

Using the SR9 in anything other than the regualr 2.4 mode is like trying to do a long range 'G' connection, and I dont know about anybody else, but I have never been able to accomplish that.
Try setting it to the normal 2.4 mode with 1,2,5.5, and 11 bitrates and see what happens.
In my testing, that was the only setting the allowed it to work perfectly. I only got 4 meg of tcp troughput, but compared to Conapys <1meg, it is great.

Quick update: I've been running with the reversed link (the Trango-end is now the SU) for over a day, with some pretty heavy traffic sent through it, and everything is holding up just fine, no disconnects.
I think this has it resolved, at least for now.
I am using NStreme with the link - maybe the Trango interference was causing issues with the AP's polling - I don't know how I'd tell exactly what was going on.
