Upgrading standalone 2942 AP from 188.8.131.52.15 to 184.108.40.206.220 makes only troubles for us.
I have 2x 2942 standalone AP's. After upgrade both of them needed factory reset to gain access to the web console. Also I had to reconfigure from scratch.
But after upgrade I faced issues where all connected clients suddenly become disconnected clients.. I had no time to investigate this issue further, so I downgraded my AP's to 220.127.116.11.15.
