Just upgraded an A5-14 AP and one C5 client to the new GPS firmware. The client connected after about 5 minutes then the AP rebooted about 30 seconds later. Logged back in and client never re-connected. GUI became unresponsive for the AP and the AP rebooted on its own about 3 times. The client never connected after 15 minutes.
Reverted back to wifi mode rebooted client and then rebooted AP after changing back to TDMA mode. After 10 minutes no client connect and then AP rebooted a couple of times on its own. Gui was very unresponsive while in TDMA mode. Rebooted AP with POE switch as I could not fully load GUI.
Reset AP as wifi interop and everything is working again. This AP and client had been up 179 days with no issues until now.
