and if you check with "ifconfig" at the same time, do you see an ip at
any point ?

what do the logs syslog/journalctl on the machine say while it tries to
connect ?

are you sure "C8:FF:28:C5:D2:58" is the device you are wanting to
connect (and not some random dude walking around in the library with a
WLAN enabled mobile phone) ?
also, does your AP perhaps have a MAC address filter that blocks DHCP
requests for non enabled MAC adresses (so you would have to add the
device to this list) ?
