Wifi - 2019 - Wanting to move away from Cisco

So who's the next best? Aruba?

We have had so many wifi issues with Cisco. New controllers, new aps, etc and the more we work on the system the more instable it is. Horrible user experience and TAC is worthless. Literally worthless.

So who does it better in 2019? We'll be moving from ACS to Clearpass so we're thinking Aruba. We've used in small scale branch deployments, but not large offices.

​

Thanks!
