Clients Dropping Connection

DMR188

I'm trying this out in a couple different environments.  I know your not supposed to do beta in a production environment, but this particular customer is really cool about it and wants to offer feedback as well.  So in this environment and why I chose it in particular is they have 6 AP's in a school classroom environment with roughly 120 clients hanging off those 6 APs.  Prior to pushing them over to the cloud, they were running off the UTM 9 with zero issues.  After moving them to the Cloud, they have said the clients drop from the AP's quite frequently, to the point I think I need to kick them back over to the UTM.  

So my question is, is there a big enough difference in the AP firmware from 9 to whatever the Central pushes to them?  Or what I'm really worried about is co-channel interference.  Being that there is nowhere in the dashboard that shows what channel the AP's are on, for all I know, all 6 are on channels 1/36. (The 6 are in somewhat close proximity to each other)  The more I think about it, that is a must have feature to be implemented before production to show which Channels the APs are on for situations like this where we can rule channel interference out.

Is there any other information I can provide or show before I kick these 6 back to UTM that might help?

Thanks

    For showing the actual channel, we created CWIFI-3484.

    That report is very valuable, so I'm glad that you tested it at a customer. 

    To get more information, can you turn on log forwarding (on the "Settings" page)? Furthermore, I'd like to know whether you used auto-channel selection on the UTM as well In any case, can you check whether the experience gets better with having dedicated channels selected?

    The AP only selects the channels on startup/config change. Background channel selection is not available yet. So it might be an issue that the APs select the wrong channels. 

    Kind regards,

    Dirk

    Thanks Dirk, I just turned that on in that Central Dashboard.  I was just on the phone with the customer and we just changed everything to manual channels for 5Ghz only (we think all the clients in that hallway support 5Ghz).  So she's going to run over there and see if that makes an improvement.  She said this morning all of the laptops and ipads were flat out unusable.  So I'll keep you updated with how it goes this afternoon after changing the channels to manual.

    As far as the UTM, they were set manually when they were on there as we noticed the auto channels liked to be the same on most.

    Thanks

    Quick update.  Moving the channels to manual solved the issue.  Had great reports from the customer this afternoon, went from completely unusable in the morning to "working better than ever" in the afternoon.  So probably all  of the 6 AP's were on the same channel, but without it showing anywhere, its an unknown.  

    I guess maybe a feature request/fix would be to enhance the auto channels with background scanning (Which I know you said was in the works).  

    Thanks

    Glad to hear that it worked out. Background channel selection is tracked internally with CWIFI-124.

    Hi Dan,

    that' s nice to hear. When the access points receive their configuration around the same time, then they have the same view and might choose the same channel. Do you know if the customer switched from the UTM to the cloud in one step, so all access points at the same time, or step by step?

    Regards Michael
