UniFi AP-AC-LR will not upgrade firmware

I have an AP-AC-LR that will not upgrade the firmware.  It's currently at v3.7.17.5220 and running controller v5.2.9.  I have tried upgrading it multiple times via the upgrade link in controller\devices.  My other AP's upgraded to 3.7.21.5389 without issue.  Any ideas?

 

Thanks,

David

Re: UniFi AP-AC-LR will not upgrade firmware

I had the same problem. My AP's are set to static IP but there were no DNS entries.  Manually enter at least a preferred DNS (I used google's 8.8.8.8 and an alternate of 4.4.2.2).  Bam.

(Got this from Ubiquiti tech support)

 

Hope that helps.

Re: UniFi AP-AC-LR will not upgrade firmware

I have this issue too, from 5.2.9 my UAP wont upgrade firmware. now I upgraded my controller with 5.3.8.2 and i though it would fix the issue. All my UAP still have 3.7.8.5016 firmware. upgrade button still clickable but after UAP restart still same firmware

 

How someone can guide me to manually upgrade or fix the UAP upgrade .

 

Thanks

Re: UniFi AP-AC-LR will not upgrade firmware

Check if the ap's have access to the internet, that is required for updating the firmware.

Controller (5.11.29): CK 1.0.4
Unifi (ca-framework-hap2.8-spf53-4.0.4.10592): UAP-AC-IW-Pro, UAP-AC-LR, UAP-AC-M & USW8-60W (4.0.43.10459)

Better WiFi coverage is not achieved by increasing transmission power, but by increasing the number of accesspoints.

Whats the memory usage showing as on the AP?

 

I only got this AP on Friday last week for my home and it updated itself ok.....but I never thought to see how much memory was used before I done the update. For info, mine is showing 47% used.

 

If this memory gets too full to perform an update, im guessing it wont manage the update and stick with whatever version it was on?

Re: UniFi AP-AC-LR will not upgrade firmware

Ill try this to allow UAP have internet access.

Re: UniFi AP-AC-LR will not upgrade firmware

Interesting... This AP was still set as DHCP, so should have had good gateway and DNS.  I switched it to static and it upgraded successfully.

 

Thanks for the tip nd262.

Re: UniFi AP-AC-LR will not upgrade firmware

I had the same problem.  Doing a force provision on my AP-AC-LR did the trick.  That AP was the only one to fail the upgrade.  It was set to DHCP, for what it's worth.

Hello @CobraCommander,

 

Enter your gateway and just use DNS servers from google.

I realize this is a bit old, but I had the same issue today - hopefully this will help someone else. We have some pretty strict DNS filtering and never have issues upgrading firmware on Unifi equipment, but for some reason v4.0.15.9872 would not update on a handful of UAPs & UAP-LRs we have hanging around. I tried at least 10 times, factory reset, etc...etc... I found that I went to the controller settings --> Maintenance and I check for firmware updates and then I cached the firmware for the UAP that I was having trouble with. As soon as I did that, every AP we were having trouble with updated the firmware on the first try. This worked for us without having to change any network settings on the APs having issues.

Re: UniFi AP-AC-LR will not upgrade firmware

Same here. But only for the UniFi AP-LR from 4.0.14.9736 to 4.0.15.9872. The UniFi AP-AC-Pro had no problem.

 

Settings>Maintenance>Firmware>Select Cache fixed this.

 

Thank you @CLSnetAdmin for sharing this info.

It worked for me too. I had problem upgrading a Unify AP-LR. I tried forgetting AP and hard reset but it didn't work for me

 

With these steps I could upgrade the firmware for the Unify AP-LR:

Settings > Maintenance > clicked on Cache column on Firmware section > Deleted pending items and click Cache again

I had disabled Automatic Firmware before doing this under Sites > Automatic upgrade AP firmware

 

Thanks @CLSnetAdmin
