Re: Intermittent connectivity loss with UAP-AC-PRO

Thanks @kyled.

 

Figuring out and resolving this bug is currently one of our highest priorities.  We have been able to replicate, but not yet in a controlled/monitorable way.

 

To help with this effort, would you be able to PM me nutty.io access to your APs?

 

Thanks in advance,

Brandon

@UBNT-BrandonI don't see a way to PM you anywhere. It looks like I don't have enough posts to use it yet?

Sorry about that. Your PM wasn't enabled in time. It is now enabled. You can also email me at Brandon dot Gilles at UBNT dot com.

Re: Intermittent connectivity loss with UAP-AC-PRO

We had a similar issue at one site (same symptoms) and the USG was not handing out the IPs.  Once we disabled the DHCP on the Windows server and enabled it on the USG the problem went away.  None of us can explain it.  The DHCP pool on the Windows server still had dozens of IPs each time this happened.  Only happend with an AC model in the mix.

Re: Intermittent connectivity loss with UAP-AC-PRO

@qiaohu Thanks for the nutty.io access.  Would you be able to PM the MAC address and IP address of the Macbook Air which is experiencing the problem?

 

Thanks again,

Brandon

Re: Intermittent connectivity loss with UAP-AC-PRO

@qiaohu For your specific issue, the problem is likely a known DHCP bug in 3.4.8 (which is fixed in 3.4.11 FW, if you'd like to try it), but could be another (potential) bug we are working out.

 

Either way, we will have a FW candidate this week that fixes the remaining potential bug.

 

Thanks,

Brandon

Re: Intermittent connectivity loss with UAP-AC-PRO

@UBNT-Brandon: Could there be a relation to my thread in the Beta forum: https://community.ubnt.com/t5/UniFi-Wireless-Beta/4-8-10-UAP-AC-LR-looses-all-IP-connectivity-of-con...

 

It's also all Apple devices with me having trouble!

Re: Intermittent connectivity loss with UAP-AC-PRO

@qiaohu@jacotec, what device is providing your DHCP?

Re: Intermittent connectivity loss with UAP-AC-PRO

@whowe82 It's the USG that provides DHCP.

Re: Intermittent connectivity loss with UAP-AC-PRO

@jacotec From what you described, it seems to be a similar issue. However, it occurs to us intermittently, not all our devices have this problem all the time. Also, we only tried controller v4.7.5 and v4.7.6, and the firmware that these two versions encapsulated. We haven't tried any beta versions. The issue seems to be related to UAP-AC products (5G hz maybe?), not sure if it's only affecting MacBook though. Most of our users have MacBook, only 3 or 4 PCs which are not actively used.

Re: Intermittent connectivity loss with UAP-AC-PRO

Hi everyone,

 

Anyone who is having this issue... would you be willing to set up a client which has the issue on both a wired and wireless connection and install teamviewer so that we can debug directly on the machine?

 

Here's what we'd like to do:

  1. Have problem client wired and wirelessly connected.
  2. Connect to client via teamviewer.
  3. Simultaneously have nutty.io access to the AP in question.

Please PM or respond here if you can help (and feel free to PM me Teamview and nutty.io credentials if you've already set this up).

 

Thanks in advance,

Brandon

Re: Intermittent connectivity loss with UAP-AC-PRO

Our issue went away when we put DHCP on the USG.  Here are all the infrastructure devices at the site:

Re: Intermittent connectivity loss with UAP-AC-PRO

@UBNT-Brandon Hi Brandon, unfortunately it would be difficult for me to accomodate this test request. The issue occurs quite randomly, and the users won't be able to stay in that status without connection for you to remote in and troubleshoot as we work in a quite busy environment. 

 

However, it this occurs to me personally next time, I will try my best to be in touch with you.

Re: Intermittent connectivity loss with UAP-AC-PRO

Okay, thanks.  The latest RC should likely help in your case.  IIRC, you're still on the latest stable, which I think may have some problems in this regard.

 

We are hoping to have the latest RC into stable late next week.

 

Best Regards,

Brandon

Re: Intermittent connectivity loss with UAP-AC-PRO

@qiaohu can you try THIS firmware on the AC-Pro?

 

You'll have to update it via the local method. I've written steps on how to do that, and you can find them HERE.

 

Please let us know how that goes.

 

Cheers,

Mike

Re: Intermittent connectivity loss with UAP-AC-PRO

I installed that firmware to my AP and haven't seen the original connectivity loss problem but now I've had a problem with 2 iPhones not connecting and just had the spinning wheel next to the SSID in settings. Turning off and on wifi on the phone made it connect. I think that might be related to DHCP?
