Bug ID: 254683
Summary: Unable to connect get IP address from WPA-EAP TTLS
network on FreeBSD 13.0-RC4
Product: Base System
Version: 13.0-STABLE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: wireless
Assignee: ***@FreeBSD.org
Reporter: ***@gmail.com

Hello,

I am unable to get an ip address from my college wifi access point. My college
uses Tunneled TLS with two possible inner authentication mechanisms (PAP or
GTC). I have tried a few different configurations but none of them worked.

Am I potentially looking in the wrong place? Could this be an issue with
dhclient?

Please note that this issue did not exist in the 12.x release series (although
my tests then were with drivers other than iwn)

here are the combinations I have tried in /etc/wpa_supplicant.conf that I can
remember:

// this one usually works when I try it
network={
ssid="networkname" // this is just a placeholder for the real ssid
key_mgmt=WPA-EAP
identity="insert my identity here"
password="insert my password here"
}


// specifying anything other than the above has always given me problems but I
// tried it anyways
network={
ssid="networkname"
key_mgmt=WPA-EAP
eap=TTLS
phase1="peaplabel=0"
phase2="auth=GTC"
identity="insert my identity here"
password="insert my password here"
}

// I also tried it with PAP
network={
ssid="networkname"
key_mgmt=WPA-EAP
eap=TTLS
phase1="peaplabel=0"
phase2="auth=PAP"
identity="insert my identity here"
password="insert my password here"
}


none of these combinations have worked.

The hardware I am working with is a System76 galago pro (not the most recent
one). the wifi chipset is an intel Wireless AC 9560. If there is any other
information I need to add, please tell me.

Thanks,

Ian Sutter

I haven't tried this in forever :( But it's possible the updates to
wpa_supplicant and net80211 changed things.

Which hardware were you using in 12.x?

I would like to request a change of the title of this bug to "Unable to get IP
address from WPA-EAP TTLS network with iwm driver"

I just tested connecting to the same network with a wifi dongle and it worked
like a charm. This leads me a believe that it is a bug with iwm driver
specifically, and not a problem with the DHCP stack.

Also, you can get a LOT more debugging from the supplicant, run it in the
foreground with '-ddd' on the command line and capture that.
