Multiple Rocket AP's disabling LAN0 on network

I'm seeing multiple AP's on 2 separate networks with this happening randomly.

 

WLAN still active, so can still get into AP over wireless, and re-enable the port.

 

Checked for MalWare, and it doesn't seem to be on any of the radios, any advice?

 

It's as if somebody is logging into them and disabling the port.  Just curious if anyone else is seeing this?

It seems they are all 5.5.6 up to 5.6.6, so I'm aware it is potential to have the the exploit on there.

 

Malware detection isn't finding anything, and this is all we are seeing happen.

I would update these at a minimum to 5.6.15 or the latest (6.0.7).  We also have signed versions of older firmware available HERE.

Re: Multiple Rocket AP's disabling LAN0 on network

Thanks, I will proceed with these suggestions.

 

We are trying to decipher if it is someone purpousely doing it, or if it is related to the exploit from firmware previous to 5.6.15.

 

So far, in the one network, all affected AP's have been with older firmware, I was told the others were upgraded, but that may have been incorrect information.

Re: Multiple Rocket AP's disabling LAN0 on network

Procedures have begun with upgrading one of the networks, from what I understand, all devices that were having the issue are running 5.6.6 or earlier.

Re: Multiple Rocket AP's disabling LAN0 on network

We have upgraded 24 devices to 6.07.

 

These have been ones that have failed at least once during the last 2 months. Of these devices 5 had been upgraded earlier, and had been up for about 5 days with no issues.

 

We have now experienced a failure on one of these APs again and found that the lan0 interface was again disabled.  Even running the new firmware.

 

Any other suggestions?

Could you forward the Support Info file from one of these units? james@ubnt.com

 

How is this unit being powered?

Re: Multiple Rocket AP's disabling LAN0 on network

Just got some more feedback, it seems that one that seemed to have the problem after upgrading was likely a different issue.

 

So, on the other units upgrade, none have disabled the lan port, so it looks like upgrading is the solution.

 

Thanks @UBNT-James
