Hi,
We’re seeing intermittent errors connecting various ios devices to a hotspot broadcast by a TX2. It’ll work fine 8 or 9 times out of 10, then we’ll get an incorrect password error on the client. Ignoring that error and attempting to connect again will succeed, so we’re sure it’s not an issue with the saved password.
One thing we have noticed is that before a failed connect, the previous disconnect will not cause any logs to be written. Upon attempting the connection that ultimately fails, some logs will be written, including a WLC_E_DEAUTH log.
Below are some logs and our NetworkManager conf.
