When I had 9.12.0 on a ZD my ac clients (iPhone 6s) were getting 248Mbps. After I upgraded the ZD1205 to 9.12.1 the clients are getting 89Mbps.
No changes were made to the WLAN. I had one WLAN with both 2.4GHz and 5.0GHz radios on. With only three clients on the system, it seems to be steering the ac clients to 2.4GHz band.
If I create a 2.4GHz WLAN and a 5.0GHZ WLAN and force the ac client to the 5.0GHz I can get 248Mbps again. But I always find the apple products have poor habits and tend to flip back to the 2.4GHz WLAN and get slow speeds again.
There is one access point, R600, in the system.
I didn't see any of this with 9.12.0
Thoughts or ideas? I don't want to create two WLANS and be broadcasting two SSID's. I'd like to have the ac clients get directed to the AC band automatically. Load balancing and Band balancing are enabled. Just like it was on 9.12.0 but something seems to be different.
