IOS devices not being able to connect to WiFi

[Zaid L]

Hi,

  We are opening new site and I added two 7210 controllers. Now, I have one SSID with pre-shared key for employes and it is working fine with PCs, Macs. EXCEPT all IOS device i.e. Iphone, ipad, ipod will connect to the SSID and get an IP address but never being able to access the internet. Any solution or tips?

What AOS version are you using?

Per-Aruba recommandation I am using 6.5.3.3

Interesting, we had a similar issue with 6.5.3.3 and iOS devices. Working with TAC we believe it was related to 802.11r but in this case we are using 802.1x.

When we did a a show user mac <mac address> on the cli we had a blank spot next to the output for dot1x authserver which lead us to believe that RADUIS was not being initiated by the controller (despite being configured correctly) and most of these users (nearly all of these were iOS devices) were ending up in the denyall state. You can see this by running show user role denyall command on the cli.

In the end we turned off 802.11r and downgraded again to 6.5.3.1 and I understand TAC are working on a permanent fix. What I can't answer is if this is the same problem that relates to a PSK network. So, I suggest you open up a TAC case to look into it.

Let me know if you want any more detail on our situation

Hi,

  Alex, thanks for the reply. I did open a TAC ticket but luckily I didn't have to use them. It was DNS problem. After I changed the DNS ip address on the DHCP pools in the controller everything worked fine.
