Using Cisco Aironet 3800 series AP's, why would a device be allowed to connect to AP, then get dropped after a while, and UI page shows devices somehow shows up as 0.0.0.0? We have industrial devices that go down to 1Mbs in order to keep connected to any network from noise, distance, RF reflections, and extreme factory conditions, the devices are 802.11g Industrial devices. Works great with off the shelf routers, and Unifi AP's etc. But for some reason, the IT doesn't know why the devices will go off line, and show the static IP's per device, show 0.0.0.0 on the UI list when they get kicked off the network or something.
I seen them be connected all day and pinged all day once, all good, then at 7PM PST time, seemed like they all started falling off the network, and IT gave a screen shot of list of devices show 0.0.0.0 as IP addresses, when they were just fine previously using their static IP addresses.
Using the devices themselves to see what the the network was telling them, one log showed dissociated due to inactivity? And was only on for a short amount of time, like 20 minutes or so, then couple more events, that weren't recognized by the devices, and then a final disconnect from the network kicking off the device. I read some where that it might have something to do with DHCP settings, since the devices require a static IP address? Thanks for "any" feedback on possible settings etc.
