Hello We have a corporate network where we facing some issues with the access point 2600 series .  . The problem is like this - The ap-s that are using  channels from UNII3 are not working for Corporate network but they can connect to GUEST network . They can see the SSID but they cannot use it . I changed manualy the channels and still have the same issue  .I have the same Access point model that are using diferent channel and for them everything is fine  I need to mentioned that all the user are using windows 10 .

I'm going to say that this is the issue:  The WLC is configured with multiple countries that have conflicting 5.0 Ghz Regulatory Domain.

Regarding to this issue the problem started last week , until than everything was ok .   For example in 1 place i have 9 access point same model but they use diferent channels 8 are 9 and 1 not . Second location same problem . 90 % of the access poits are 2600 series . the stramge think is that i have some location where the ap-s are using a UNI-3 Channels and everything is woking fine .

i tryed to find the  issue with debug client from wlc . have no idea anymore where to get it .

Try upgrading the firmware of the WLC.
