any idea why iphones and ipads are not connecting to 802.11ac? it is always connecting to 802.11n. even if i turn-off wifi off and then on, it is sticking with N. anyway i can configure the controller to allow these devices to always connect to AC?
2504 WLC 8.5, 3602i with AC modules
The iPhone and iPad are newer devices that have 802.11ac NIC’s correct? Test with an open SSID and see if the devices negotiate. If other devices negotiate to ac, you don’t have an issue with your configuration, just might be the device.
phones are iphone 7 and 8, ipads are a little older i think ipad air but shouldn't have any problem with their NICs as they used to connect through 802.11ac before.
tests done with open authentication have the same results sadly. i did try to change wireless-advanced-network profile-client network performance-default to throughput and test with my phone, it did connect to 802.11ac once but after turning off then on wifi it goes back to 802.11n. so something from the controller should have been configured wrongly i guess
yes, wpa and wpa2 are enabled. i have tried with open authentication local web policy and the result is still the same.
i didn't have these problems before and i used to connect to ac just fine so it just surprised me that i can no longer connect to ac. last time i did some re-configuration was about 6 months ago so its hard for me to recall the last changes i have done.
yes, wpa and wpa2 are enabled
Choose only one. It is either WPA or WPA2. Don't turn on both and "hope" the wireless clients can make the right decision. The wireless clients won't.
