This is a Cisco wireless network (802.11a/b/g/n) on both 2.4 GHz and 5 GHz and a Ubiquiti router / WPA2 authentication, 500 Mbs WAN. The Os4 and OS2 had operated for weeks if not months without issue until the firmware upgrade on the OS4 to V81. (The Os2 continues to work fine.) If the router or the wireless were to disconnect a client due to something (?) like a bad roam or wrong frequency, I would not think the OS4 client should crash and lock up the hardware, that isn’t normal WiFi client behavior, it should continue to try to connect to an available WiFi network in the config. At least that’s how it had worked up until recently.
No updates or SW changes in the WiFi network for about a year.
One possibility is that the OS4 hardware doesn’t like WiFi environments that have more than one AP for a given SSID, and it locks up when it sees such (I.e - same SSID on Channel 1 and Channel 6 but two different MAC PHY addresses.). There are 3 APs in this WiFi Network. Again, the OS2 seems happy anywhere in this same network for weeks at a time. There are probably 50+ clients on this network, and no other client experiencing this behavior.
Are there other logs that are more verbose that I can pull on the OS4 besides the one I posted? I sent the full log file to SharkRF (it is a snippet above).
