dmesg prints a time based log of system messages. The most recent messages are at the bottom of the file. You could for any errors/warning/info regarding hostapd or wireless authentication, etc, that might be useful. The stuff that flies by at the beginning are older messages.
An alternate command to try is: tail /var/log/messages which should print similar info. „tail“ prints the end of the the file.
tail -50 filename prints the last 50 lines etc… tail -f filename monitors the file and dynamcially prints the end of the file as it grows.
Cntl-C to terminate. /var/log/messages is the file where system messages are logged.
