Wifi quality in a commercial facility

[marcplante]

I'm working with a use case of a large building that seems to have slightly variable wifi functionality. I have 200 end points in a building that I track for availability with a console by effectively pinging every 10 minutes. First thing in the morning. All devices are online.

As the day progresses, I lose 15% of the devices to spotty availability.They seem to drop. and add for short periods of time. I need to do more monitoring to understand if it is specific devices that are dropping, which might point to weak spots in my Wifi grid, or a random selection of devices that point to structural weakness in the platform.

standing at spots where a device is losing connectivity with a Wifi analyzer on my phone, I see signal strength fluctuating from -40 dBm to -65 dBm.

I'm wondering if there is something structural (building voltage mid day vs quiet hours, network traffic mid day vs quiet hours) that I should consider.

What major variables should I consider?

Thanks,

Marc

If it's as the day goes on, sounds like they're either being over-loaded with traffic or the subnet of the network they're on is running out of IP's possibly?

Are you using a wireless controller? Have you checked the usual suspects such as microwave ovens, wireless security devices, wireless headsets etc?

Are you on 2.4ghz or 5ghz?
