I've tried to get their attention before and it winds up being a constant loop with Support. The B11s work good enough that it's not worth my time to chase the last couple hundred Mb/s. I just gave up on the B5.

10 We need you to connect these to the cloud so we can monitor them.

20 Okay we see your monitoring data, we will circle back in a month

30 Hey try this latest firmware update.

40 Are you sure the antennas are aimed right?

50 Try replacing the cables

60 Oh, your chains are unbalanced by 3db, that's the problem.

70 GOTO 20

By about the 3rd iteration we replaced the B5s with Airfiber using the same antenna and haven't touched it since. I've just accepted that the B11 link won't hit its advertised speed and quit spending time/money on it since we are putting in fiber soon.

I pulled the B5s back off the shelf a few months ago just to see if maybe newer firmware would fix, and once again a tiny bit of interference dropped a link that was doing 1.2Gb/s to 7mb/s or less.

I'm testing some B24s in a real-world link in a couple of weeks. I hope they do what they're supposed to.
