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.
Okey. But I had basically two problems.. upgrading and client disconnections.
Wich one You mean?
I have strange feeling, that if I hade factory reset done before upgrade, then probably the upgrade part should succeed. I have this feeling because if I downgraded 9.7 to 9.6 then fully configured 2942AP hangs somehow too and needed hard reset. But on the other AP I did factory reset before downgrading from 9.7 to 9.6. And I succeeded - no hard reset needed after downgrade.
