R510 AP failed firmware upgrade and won’t become active in network

[matt_haun_iqhjc]

 Added a third R510 AP to my network. All APs need a firmware upgrade. One original R510 upgraded fine and the new R510 upgraded and connected fine. The second original AP failed. Web interface shows the previous firmware version, but when I go to the admin function to upgrade firmware, it says no upgrade is required. Upgraded version 200.8.10.3.243. Failed version 200.7.10.202.94
