8.1.3 and 8.1.4 keep crashing on cpe, performance still poor as well

hi, every time i log into any of the litebeams running this software then there is  a crash report. they reboot and connect ok, but yeah no good

 

best performing software is still 8 beta 19

 

the rest of the network is running this and is fine apart from performance not as good as 7

 

will be rolling back to 7 now i have figured out what version i was running 18 months ago and it was much faster than anything with 8 in the name

 

ditto now that it is not a mixed environment then will be rolling back all 6 devices to 5, which again was much faster

 

ubnt have pulled all these versions from their website but with a bit of hunting around i found then all and have the complete collection now

 

thanks

I also had my first crash on a PBE AC Gen2 on 8.1.4 today - so the problem isn't completely gone yet. However, other units that had several crashes on 8.1.3 has been stable since upgrading to 8.1.4 (knock on wood...).

I just upgraded a access point and cpe's yesterday to 8.14 and I had 4 powerpeam ac 400's crash. None of the 500's crashed.

When you guys say "crash", are you referring to the "unexpected reboot" message you get on login? I have 6 Nanobeam AC-16's that are doing this a lot, on the very latest firmware.

Re: 8.1.3 and 8.1.4 keep crashing on cpe, performance still poor as well

Hi guys,

 

Same problem here. "Reboot unexpected"...

 

LiteBeam 5ac16 PTMP -> 20~25 users with LiteBeam 5AC 23.

 

Random reboots/crash for everyone... Mainly with large volumes of traffic.

 

Many RX erros on Switch port (1000 full, HP Network)... I'll change to FAST.. I read that this can help.

 

Some files provided to Ubiquiti support... probably we'll need to upgrade and have lucky!!!

 

Regards,

Luiz Ferreira

Re: 8.1.3 and 8.1.4 keep crashing on cpe, performance still poor as well

This (the watchdog reboots) has been a known issue in the beta forums for about 6 weeks (https://community.ubnt.com/t5/airMAX-AC-Beta/Repost-8-1-3-betas-being-quot-reset-by-watchdog-quot/td...)

 

If you are running a Gen1 radio I would flash back to 8.0.2.  If you are on Gen2, you should be safe on 8.1.2-beta2 (https://community.ubnt.com/t5/Product-Testing-Firmware/airOS-v8-1-2-Has-Been-Released-for-Beta-Store...)

 

If you want to stay on 8.1.3 or 8.1.4 you can also try

1. download config backup

2. open backup in text editor and add "airview.status=disabled" as last line (without quotes)

3. restore backup to radio

4. reboot radio

 

Keep in mind everything above here is just my personal opinion and experience.  There are people who are having this issue on 8.0.2 but it is not nearly as common.  And there are people with 100's of radios on 8.1.4 with no reboots.

Re: 8.1.3 and 8.1.4 keep crashing on cpe, performance still poor as well

Hi guys,

 

Thanks for the clue... I downgraded the firmware to 8.0.2, I'm using 5AC16 PTMP and 20 costumers with 5AC23 all Gen 1.

 

I downgraded a PTP with two 5AC23 gen1 to... the performance stay good at last 24 hours.

 

At this week I'll monitor throughput and uptime x connection time and post here the result.

 

I've never worked with version 7... can be a better choice?

 

Regards,

Luiz Ferreira.

I am 100% happy with 8.1.2 / 8.0.2 although I only manage two very simple PtP links.  There seem to be some that prefer 7 but I have no experience with it, I jumped from 5.something (an M device) straight to to 8.1.2 on an AC Gen2

I've been seeing this a lot on our CPE's as well that are using 8.1.4. They crash, reboot and reconnect but it's problematic for our SCADA systems. Our users get all kinds of alarms are their SCADA systems because of the interruptions.

I also thought I would mention that I didn't see this problem until I upgraded some of my CPE's to PBE-5AC-Gen2 equipment. I haven't seen the Gen1 AC gear crash yet.

A week ago deactivate airview. Since then, no reboot in 4 PowerBeam 5AC 400 ISO with WA.V8.0.2

Upgrading Nanobeam AC Gen2 to 8.3.1 or 8.3.2 from 8.3 with wireless mode set to "Access Pont ptp" on one antenna.

I constantly (3-4 minutes frequency) get this watchdog error message:

 

"Unexpected reboot detected. The following information will be reported to Ubiquiti Networks.

Device crashes can be caused by unstable power. Please check PoE adapter, ethernet cable and connectors."

If I set  wireless mode set to "Station Pont PTP" it is rock stable, but useless since it must be an AP

Update:

I had a long SSID. After changing it to a short SSIF i.e. ubnt, no crashes have occured so far (for almost one hour)

@G400 I want to see what SSID caused such reboots. Can you e-mail me it in private to edmundas@ubnt.com

 

Thanks,

Edmundas

Never tried 8.4.0 beta 1 but this appears to be fixed in 8.4.0 beta 2.

 

Thanks for your efforts.
