WLAN limited connection

Hi, I'm not sure if this is an AP issue or Controller issue but here's the situation:

We have a Cisco 2500 Series WLAN Controller and 10 AP's with model# AIR-CAP2602I-A-K9. Our form of authentication is certificate based. using WPA-Enterprise AES. As long as the computer has the machine certificate, it will be allowed to join the WLAN network. Including in this setup is it gets the IP address from our DHCP Server(Windows Server)

The weird thing is, we made sure that a specific unit is installed with the required certificate, was able to join the network, checked if the IP came from the DHCP(yes it was able to acquire the IP). BUT it just shows limited connection inspite of having the DHCP address.

So I doubted that it might have an issue with the WLAN adapter, I tried to connect to a 3G pocket wifi using WPA2-Personal and it was able to connect and browse over the internet.

So knowing that the adapter is good, tried to check inside the WLAN controller and its status is associated, tried to remove and rejoin and still same result. I'm not sure if I need to verify the radius server if there's a limitation for number of clients to authenticate but I doubt since this radius server is just for auth, it shouldn't have a limit(correct me if I'm wrong).

Or are there other things I need to check or am I missing something?

Regards,

Jeff

The issue happens randomly

The issue happens randomly because we have approx 600 laptops and apple devices(ipad and iphones).

Will try that suggestion and will get back to you next week.

Have a great weekend ahead!

Jeff
