Hi have a 5700 20mb Backhaul… All appears to work fine,
but every 2 mins or so the link drops for 4-5 seconds and then
restarts all by iteself.
I really need so stop this quickly… Does anyone have experience of
this type of problem. There is nothing in the logs of either end. Here are some of the details of the link.

You can very likely stabilize the link by dropping the BHs down to 10Mbps.
Do the Session Count, Reg Count, and Re-Reg Count increment each time the link drops and reconnects? The master shows received Power Level and Jitter that’s significantly worse than what the slave shows. You could run the Spectrum Analyzer at each end to compare the interference levels and maybe switch to a differnent frequency.
Thanks Teknix,
I had the same thought and dropped the rate to 10, I also
went through ever frequency and tested it, here is the new results,
but the problem persists.

It does appear that the Reg count and Re-Reg are incrementing.
Any ideas?

I see references to both v6 and v7 software in your listings. Try upgrading or downgrading both units to the same software, boot, and FPGA versions.
