I have 6 Wism WLC's with 900 APs.
Technicians in building A had no problems connecting clients to WLAN-1 with WPA2-PSK (AES) on most laptops. However they could not connect any R500 laptops. They would not get past DHCP.
I moved all the Access Points in that building to a different controller and they started working. The WLAN config is from a template so it should be the same. I check the Interfaces on both controllers and they look the same.
I had suspected problems with this particular controller before hence the reason I moved the APs off of it while troubleshooting. Do you think it could be a bad controller?
What else could I look for. It seems so odd to affect only one model of laptop?
