Hiya getting some AP disconnected alerts several times a day but haven't noticed any downtime from the APs in question and they all have uptimes of 3 days currently despite several alerts during that time. One AP is backhauled over a NanoBeam PtP link and the other is plugged directly into an EdgeRouter X which itself also has uptime of 3 days currently. Looking into the logs on the EdgeRouter X doesn't show up anything out of the ordinary since the reboot (just connections/disconnections on the port that goes to a lounge PC which is expected). Has anyone else seen this issue? Will investigate further on my side if it looks like it's just my site.

I was getting a few of these, until I opened the door to the router cupboard. None since, so seemed to be heat related. Next project when its cooler in attic is to install an extractor fan in ceiling of cupboard.

Maybe yours is the same issue (heat)

Logged into one AP and seeing this in the logs:

Seems it's falling back to SELFRUN mode. Strange it's trying http://unifi:8080/inform.

However it does occasionally contact the correct gzunifi site as I've found earlier in the logs.

Interesting theory about the heat, I've had hotter days than the last few days and it's been fine. Will keep in mind though.

For anyone wanting IPv6:

If you're on BigPipe or 2degrees and have got your USG on the controller flick me a PM and I can enable IPv6 on your USG. I've done this with a few USG's on BigPipe already since there seemed to be a bug when a IPv6 announcement was received by the USG the behaviour in some cases was "Oh crap - PANIC! What do I do? Reboot" which was very suboptimal. For those who now have this enabled well, enjoy your new Badge on Geekzone!

For Vodafone FibreX however I tested a configuration I made and it did a provision loop - if anyone is willing to test FibreX (and doesn't mind if their connection goes down for a few minutes) then I'd be happy to hear from you also.

Several people have noticed the controller crashing every night - I ran into a memory leak issue with controller version 5.9.23 which would cause the controller to crash and at the same time pin one of the Java processes at 100% CPU use until I manually did a "kill -9" to it. This appeared to happen when the controller backup process started.

I've updated the controller software to 5.9.26 which has a fix for a memory leak. Will be monitoring it closely to ensure it doesn't crash.

My AP has disconnected twice in the last 12 hours. First was about 3am this morning, which I took to be a routine update, but then it just disconnected again about 20 mins ago. Any ideas why this might be?

It may be a coincidence, but my FritzBox 7390 router died this morning, and so I've had to pull out an old HG659b router to make do in the meantime (also off to read the Router Guide to work out what to buy as a long-term replacement...). Any chance that there is a connection between last night's disconnection, the router dying, and the recent disconnect? (I suspect not, but just in case it's relevant...)

3am is when I have the upgrade maintenance job run to upgrade access points to the latest firmware so that answers that. Not sure about the other issue though, I presume you've rebooted it?

Here's a question for the Unifi brains trust. :)

I want to create a rule in my Unifi Router (Firewall rule?) so that I can easily add external IP addresses as I go, that I want to block from any access to my local network.
How best would I go about doing this?

Thanks

Grant

I figured the 3am disconnection was planned, so I wasn't bothered by that.

I checked in on the Controller page about 1.30pm and it shows it as connected, so all is good for now but will keep an eye on it.

Hey Michael,

I am not using your community controller, but am running the controller + USG locally. I am on BigPipe and was wondering what is involved with enabling IPV6 on the USG?

Many thanks,

Ben

BigPipe no-longer have IPv6 (see here: https://www.geekzone.co.nz/forums.asp?forumid=158&topicid=236018) - you'll have to change ISP's to get the full goodness of IPv6. I've got USG's on both 2degrees and Voyager with IPv6 successfully working :)

I'll take a look at this when I get a spare moment. It is pretty straight-forward.

Big thanks to Michael. Had the pleasure of upgrading from my Vodafone hub to a USG and 8 port unifi switch and finally adding my ap to a controller again. (PC got formatted and couldn't t get the controller running again 😂)
Was all super easy with Michael's help and this Cloud controller.

Hi Michael

Recently I purchased EdgeRouter 4 and UniFi AP AC LR after reading your router guide.

I setup the router using your tutorial, pretty straight forward, did not have any problem.

However, I am having a problem with the AP setup.

I installed UniFi SDN Controller 5.9.29 for windows, and for some reason, it cannot detect my AP.

Here is a screenshot of my DHCP Server:

My PC is connected to Lan 1, and I have connected AP to lan 2, with the PoE adapter.

I have added "52.63.76.40" into the UniFi Controller portion of both lans, according to your other post.

But still, neither controller nor discovery tool can detect the AP.

FYI my ISP is BigPipe

If you can guide me to the right direction, it would be much appreciated.

Thanks in advance

Kironz
