We have a WLAN setup as a provisioning SSID for ISE. It is configured for mac-filtering, radius NAC, and AAA override. We have no issues with Apple or Android devices connecting and getting redirected to ISE web portal page. Chromebooks are having intermittent issues getting connected, specifically getting a DHCP address. They associate, but stay in DHCP required state until they timeout . Eventually they timeout and disaassociate. I can bounce the WLAN or delete the client from the WLC, and they will connect.
When this issue is occurring, these devices will also not auth to other 802.1X configured wlans on this controller.
These devices have no issues connecting to an open guest network. Any ideas?
We have had connectivity issues with Chromebooks, but mostly this ended up being specific Chromebook issues and how they prefer different networks. We have went through a controller code upgrade since this. We were on 7.4, and are now on 7/6MR3.
