C25 some devices can't access

[Michael_Ezell]

I have a C25 wireless controller. Lenovo laptops and Windows Surface Pad Pros are not able to access my guest network. Just about every other device does. Firmware is 9.21.06.0006. The guest network is open and does not connect to the internal network. It is running off of a Comcast line and that is the only thing on it. Is there an update for this? Has anyone seen this before?

Thank you for any information you can provide. The board and senior leadership are getting restless... very restless.

As Joseph mentioned we'd need to unterstand what "not access" exactly means.
Also which AP and which radio is used.
The best would be if you post a screenshot of the radio settings + advanced radio settings + the QoS settings of the WLAN service.

Can you tell us which AP's you have? Also, are you directing to a guest splash page? On the devices that cannot connect, have you had the opportunity to test with one of the machines? Is it getting an IP address? What kind of rule set are you running for authenticated, non-authenticated guests?
