Apple devices Wifi issue

[sagarshaha]

Hi,

We recently purchased brand new 10 units of Cisco 9115AXP and 1 unit of Cisco 3504 Wireless controller.

The issue is, some of the Apple laptop (both MacBook Air and Macbook Pro) users couldn't see the SSID and if they see and connect, the connection is intermittent.
It works for a while and then auto-disconnects. After that, if we try to connect, it doesnt connect at all.

Then, we have to turn wifi OFF and then wait for a while and then it connects. Sometimes, if it still doesnt connect then we have to restart the laptop.
This is super frustrating as we have around 10-15 users impacted with this issue.

Some of the mac's are on MacOS Catalina and some of them are still on MacOS Mojave.

We tried talking to Cisco support but they didnt helped and asked to update Wireless drivers. I have never seen Wireless drivers update for Apple laptops ever.

Appreciate if you experts can give me some lead that where we might be missing out.

Thanks

Hello,

We have upgraded last night to AIR-CT8540-K9-8-10-142-0 and AS_550_8_5_164_216.

we have also changed our Dorm Buildings from 40MHz channels to 20MHz and turned off some 2.4GHz radios.

Will update later this month after all of the Students are back to see if this has been resolved.

Happy New Year!!!
