Yep. That is marginal at best.
I've found MT *much* more stable beyond -83 than UBNT hardware by far. UBNT forums seems to support that as well. The majority flog you for a signal worse than -70. I have a lot of full speed MT links at -79. UBNT seems to need -70s to be stable. You were living on the edge. ----- Original Message ----- From: Jeremy To: [email protected] Sent: Wednesday, October 07, 2015 3:11 PM Subject: Re: [AFMUG] Client can't connect since UBNT 5.6.2 Firmware upgrade I would not expect -86 and -89 to stay connected, on any firmware.

Since this update, one of the clients will not connect. This AP originally had 6 SM’s connected at 5490. After the upgrade from 5.5.4 to 5.6.2, 2 of the SM’s didn’t come back. These 2 were not at the best signal (-86 and -89). If I swapped frequencies to 5740 the 1 connected at -86 popped back up at an -88 and the other SM’s are ~-2 db. But still no sign of the one that was at -89. This led me to believe UBNT probably lowered the output power for DFS frequencies somewhere between 5.5.4 and 5.6.2… One would think that downgrading the SM’s and AP back down to 5.5.4 would put things back the way they were but that doesn’t seem to be the case. I even sent a tech onsite to swap out the unreachable SM with one that had 5.5.4 on it. He said the one with 5.5.4 and the one with 5.6.2 both see the AP at -89 under “Site survey” but won’t register to the AP. I’m at a loss here… Does anyone have any suggestions of things to try, or a magic firmware version (folks on the UBNT forums say 5.5.4 is best for DFS frequencies) that might make this AP act the way it did prior to upgrading to 5.6.2? I’ve already tried every other 5 Ghz Frequency available (with a mix of different country codes), most with worse results. Thanks, Justin [email protected]
