Re: [FIRMWARE] 4.0.9.9636 for UAP/USW has been released | Stable Candidate

@jfruehe The retries and dropped packets weren't quite right in 3.9.19, we audited them so that they are accurate now. Association failures in the thousands was a bug in the way band-steering was implemented years ago, so if you don't have any actual blocked clients, that number should normally stay pretty low now.

@UBNT-jeff Awesome. If that’s the case then I think I could start updating. I updated a few as test ones and all has been good. I just don’t do the entire network until it looks stable territory

The problem I reported with 4.0.8 with Amazon Echo Dots in marginal 5GHz signal strength environments on the UAP-AC-HD is also causing an issue with 4.0.9.  Had to revert to 4.0.6 again to get it working reliably again.

 

Original report below:

I think there may be a bandsteering issue on the UAP-AC-HD.  I have an Amazon Echo Dot that is in a location where it's marginal for 5GHz, so usually connects at 2.4GHz.  Since upgrading from 4.0.6 to 4.0.8 on the UAP-AC-HD it won't connect at all, whereas my other ones that are better positioned for a 5GHz signal are connecting at 5GHz.  Reboots on AP and Echo don't make any difference.  Revert to 4.0.6 and it connects at 2.4GHz as usual.

 

I do have bandsteering enabled on this SSID, but it has never caused an issue with the Amazon devices before, so this behaviour seems to be new with 4.0.8.

Controller 5.9.32.

 

@UBNT-jeffIs anyone researching this?  I didn't get any response in the 4.0.8 thread to this issue either.


@plemonde I have reached out and will work with you to get this issue resolved.

Re: [FIRMWARE] 4.0.9.9636 for UAP/USW has been released | Stable Candidate

Giving this a try on a couple of AC-Pros. 

 

We've had a lot of DHCP issues lately (all devices on a single AP get APIPA address as if the AP is not passing through the DHCP requests - fixed by an AP reboot, and random APs with model only common factor) and I've got to the point where backing down to 3.9.42.9152 more or less fixes the issue.

 

Interestingly this is purely on the AC-Pros, the AC-HDs we have on 3.9.54.9373 have never seen the DHCP issue.....so will see if this firmware might fix the issue for the Pros.

@capeschools How many wireless clients do you ever have on a VLAN? Do you use multicast block? What does channel utilization look like?

@UBNT-jeff

 

Client numbers are maybe 600-800 on any given day, we do not do multicast blocking and channel utilization has been really good since we diabled 2.4 a while ago as that was always an issue but no problems with 5.

Re: [FIRMWARE] 4.0.9.9636 for UAP/USW has been released | Stable Candidate

@capeschools I can't recommend multicast block and extending ARP timeout highly enough then, in your case: https://help.ubnt.com/hc/en-us/articles/115002806907-UniFi-High-Density-WLAN-Scenario-Guide (Scroll down to Tips/Recommendation for High-Density WLANs, I'd at least do 1-3) This will be recommended, and even potentially automatically enabled (if allowed) in setups like yours in the future.

@UBNT-jeff I thought I had read on a forum post about issues with blocking that impacting things like AppleTV discovery etc?  Am I wrong in that?

Error updating UAP-HD

Hello my current configuration is:

 

1. Unifi Controller

Version: 5.9.29_11384

 

2. Gateway
Firmware version: 4.4.34.5140612
Hardware: USG
Model: UniFi Security Gateway 3P
Status: Connected

 

3. Access Point
Firmware version: 3.9.42.9152
Hardware: UAP-HD
Model: UniFi AP-HD
Status: Connected

 

I tried to update the UAP firmware without any success.

This are the version and method I've  used:

BZ.ipq806x.v3.9.45.9203... manual and Uni SDN Controller (custom upgrade)

BZ.ipq806x.v3.9.48.9248... manual

BZ.ipq806x.v3.9.50.9295... manual

BZ.ipq806x.v3.9.54.9373... manual and UniFi SDN Controller

BZ.ipq806x.v4.0.9.9636... manual and Uni SDN Controller (custom upgrade)

 

Manual update:

download the binary and check the integrity (sha256)

scp firmwarefile.bin user@IP-of-UAP:/tmp/fwupdate.bin
ssh user@IP-of-UAP
syswrapper.sh upgrade2 &

 

UniFi SDN Controller both methods are:

Through devices webpage

Through properties - config - manage device - custom upgrade

 

Something to check on /var/log/messages or any other think?

Any help to update?

 

 

TX.

Re: [FIRMWARE] 4.0.9.9636 for UAP/USW has been released | Stable Candidate

@capeschools As long as you have a USG with the MDNS service enabled (or something similar), anything that uses MDNS should be OK. Services that use other discovery protocols may need to be added to the multicast block whitelist.

@luisesparza Is the current firmware on it v3.7.x? You may need to use an http URL instead of https in that case.

@luisesparza  Are you able to send me over the logs through PM?

 

The var/log/messages log over in a txt file.

 

Thanks,

Re: [FIRMWARE] 4.0.9.9636 for UAP/USW has been released | Stable

This firmware has been moved to stable status, with the exception of HD/SHD/XG/BaseStationXG. We'll be posting 4.0.10 shortly (initially as a stable candidate), which likely will replace 4.0.9 as the current stable in the near future.

 

Cheers,

Mike

4.0.9.9636, original UAP: reboot loop?

[ Edited ]

I just tried to upgrade my UAP (I think it's the original: saucer-shaped little MIPS thing, non-outside version) from 3.9.54.9373 to 4.0.9.9636, because the controller suggested it.

 

It dropped off the net half an hour ago as it usually does while rebooting during the upgrade, and never came back Man Sad I guess I'll have to look up how to recover from a failed firmware upgrade...

 

Hm pulling open the cabinet it's in, it's flashing amber for a few seconds, blinking green very briefly, then going off again for a few seconds before going amber again. I wonder if this is a reboot loop...

 

Looks like it. On restart it flashes green and amber very briefly, then the light goes out: this might seem normal because i normally have the thing in a cabinet with the LED off, but it's not responding to pings nor to ARP broadcasts. 

 

Rebooted again, and the loop restarts: five seconds of darkness, five seconds of amber, a very brief triple-flicker of green, then the cycle restarts. Once per cycle we see this on the wire:

 

22:52:12.119003 IP6 fe80::200:24ff:fecb:c6a3 > ff02::16: HBH ICMP6, multicast listener report v2, 6 group record(s), length 128
22:52:12.656703 IP6 fe80::200:24ff:fecb:c6a3 > ff02::16: HBH ICMP6, multicast listener report v2, 6 group record(s), length 128
22:52:13.096407 IP6 fe80::200:24ff:fecb:c6a3 > ip6-allnodes: ICMP6, router advertisement, length 64

 

but nothing else.

 

(An hour later: successfully TFTP-downgraded back to 3.9.54.9373 and readopted, after a bunch of random panics because I have done this literally once more than six years ago and I have long forgotten all about it: 1) it's really hard to hit the reset button on a UAP and I missed the first four times; 2) your tftp instructions do not quite apply to modern Linux distros, which use tftp-hpa: a simple "tftp -l 192.168.1.20" will suffice as the command line with no need for a -p or a filename except in the 'put' itself; 3) I needed to unblock a bunch of firewall rules to let the tftp DATA packets through; 4) it was not at first obvious that if you've changed the controller port because 8080 is already in use, the only L3 method that works to trigger readoption is ssh because none of the other methods have a way to specify a port number...)

 

I think I'll hold off until 4.0.10 is pushed. 3.9.54.9373 -> 4.0.9 on a UAP does not really seem to work well, and I'm not trying again at this time of night! but God I love the fact that ubnts are unbrickable like this. (It also helped reduce the panic that I have a spare that has literally not been touched since it was bought, so I know it must still work.)

Re: 4.0.9.9636, original UAP: reboot loop?

@NullNix There have been some known issues with upgrading the original UAP for quite some time, which is why we are upgrading the base OS there. We have made some improvements to upgrade stability even since 3.9.54. Sorry for the inconvenience, but once we get to the new OS, things should work better on the original UAP.

Re: 4.0.9.9636, original UAP: reboot loop?

Yeah, I'll give the next release a try. I know this hardware is by now utterly antique and do plan to upgrade it... but not right before Christmas! (And it's amazing that it's still getting updates at all, in this world where most embedded systems vendors drop support for a product a year or two before the hardware is actually on sale. Far from being disposable, at this point my trusty UAP has actually lasted longer than any other computer I own. Talk about service!)
