Need more information to help. What type of encryption are you using?  If you test with an open SSID, does the device still have issues roaming. Have you upgraded the client driver?

Can you post the show WLAN <WLAN id>

Problem is fixed for mostly all laptops after we upgraded the WLC to 8.0.140.0---

But not for the devices that runs WPA1-TKIP/mic.

[Scott Fella · Accepted solution]

You will typically have issues if your WLAN has both AES and TKIP enabled. Best to only use WPA2/AES.  If you really need to also support WPA/TKIP, the crest a new WLAN with a different profile name but same SSID.  Make sure that one only uses WPA2/AES and the other only uses WPA/TKIP.
