Devices Android not connecting SSID with WPA2 Enterprise

[clauscosta]

Hi All

I am having problems with android devices software version 7 and higher for example galaxy J7 prime to connect to our SSID configured with WPA2 Enterprise...

The request neither arrives to authenticator.

Network Infraestucture:

WLC 5520 -version 8.3.143.0

SSID with 802.1X

APS 1852I in flexconnect mode (data e authentication local)

Authenticator ISE 2.3 with 4 patchs applied.

Testing with another android version 5.1.1 (ASUS_X014D) the same SSID and same user/password works fine.

Apple devices also works fine.

Same device connects to SSID with PSK without problems

Thanks in advance for any help

if onl yone type of device is gaving issue then .....

1. update the software (if you can) on device  and try again...

2. if still fails then contact to cisco TAC.

Regards

It may have a connection with the certificate presented by the authentication server
if possible enable the option to ask for certificate when connecting to the ssid and see what response you get

[clauscosta]

We tried to use several android versions, 5, 6,7, different vendors (motorola, samsung) and same problem
I only connect with my device that is a Asus version 5.1 and another samsung that is using version 4.2.2, besides Apple phones.

Could you please post the ISE log so we can troubleshoot your issue?.

[patoberli]

Depending on your radius server setup, you also have to fill out the Android field "Anonymous Identity" which is just under the Identity (username).
Fill it out with the same username.
I do more tend to a certificate issue though, or a misconfiguration on the SSID. You have not enabled WPA or TKIP, right?

[clauscosta]

Thanks guys for your suggestions, below the answers about your requests.

I didn't try to fill out the anonymous identity, I'll test it and post if works

At the WLC I just configured WPA2 and 802.1x, the radius server is ISE 2.3

Certificate at the device mobile side is not used, on the phone we configure PEAP with MSCHAPv2 and to not validate certificate.

strange that we have this problem only with android phones...Apple phones is working well

[clauscosta]

I tried with "Anonymous Identity" filled, same behavior :(
But I made a change that did the connection works...I put the SSID hidden and worked...but Why? why works in that way and not with the SSID broadcast? I don't know yet...besides that I need to leave the SSID broadcasting.
I tried to change the SSID name thinking that could be something with the characters quantity, but no as well.
In Summary I still have a problem...

[patoberli]

Can you please post the ISE log of one of the affected devices? It should arrive at the ISE, but might not get logged repeatedly when wrong (default setting).
Check this: https://community.cisco.com/t5/security-documents/configuring-anomalous-client-suppression-on-ise/ta-p/3161437
This can cause "wrong" logging on the ISE, something I really don't like when troubleshooting.

[pieterh]

that is a good lead from patoberli!
you can locate the device under devices right-click and select "bypass-supression" to temporarily re-enable events in the log

[clauscosta]

patorbeli,
I'll try to do this, but I guess is not that, because I tried many times with the device and not worked with broadcasting SSID, when I just put the SSID hidden worked just in time.
Thanks for your contribution.

i'd check again what certificates are used.

look at this thread that states

I did essentially prove that it was related to the self-signed certificate.  I pointed my wireless controller to another radius server (ISE 2.1) that has a real certificate on it, and it worked immediately.  No other changes were made to the SSID, or anything related to the wireless itself.  It appears that Android 7.1 is not ignoring the validity of the certificate, even though I configured it to do so.  If you have a purchased/trusted certificate on your radius server (which is almost never the case), it will work fine.  If you don't, it won't work at all.

Hello Guys,
I am sure that is not a problem related to ISE, cause:
1 - If I just disable broadcast SSID the request goes to connection sucessfully immediatilly.
2 - If I enable broadcast SSID, the connection neither arrives to the ISE, collecting debugs at WLC and AP I can see that the device request is changing to 802.1X to Unassociate status
