We have 2 DHCP servers that load-balance.  They are ISC (currently, we're
going to move to Infoblox, hopefully over the summer).

 

The phone (per the user): It is a Google Nexus 6P.

How many dhcp servers do you have and do you have multiple routes? Let us
know what you find.

Thanks,

Kanan

Yup; that's my next plan.  Was just hoping someone else had seen something.
The phone works on a personal wireless (hot spot), but just doesn't seem to
want to do DHCP here on campus.

Are you sure the phone is sending DHCP Discover packets? You mentioned it's
not working on the open SSID, you may want to try connecting the phone to
the open SSID and capture OTA packets to see what it's doing and start from
there and move towards the DHCP server.

Danny,

 

Try adding the domain in the profile for which the cert was issued

So, I've got one client (1!) who is running Android 7.1.1 and no matter
which network (our 802.1X, eduroam, or even the "open" captive portal SSID)
the user tries to connect into, he gets authenticated (on eduroam and our
802.1X SSID), but we never see a DHCPDISCOVER from his phone; it passes the
AAA (802.1X), but will just not get an IP.  Thoughts?  (other devices work
just fine).
