Hi,
I have a RFS40000 controller with some adopted APs (models 6511, 6562,7502 & 7562). My firmware on all of them is 5.8.6.0-011R.
I added an AP7502 which has the firmware 5.8.4.0-034R, I am trying to upgrade that AP from my controller but I receive the following error: "update error: unable to get update file, ftp/openssl/tar". What is wrong? Do I need to do something else before upgrading that new AP7502?
