WLC 3504 / AP-AIR-3802 low speeds

Hello all,

I'm in the process of deploying a new customer site and I'm finding the wireless speeds to be less than ideal. The infrastructure is all new and there are no users online yet. Topology includes an ASA5512x , C9500-16x stacked and C9300-48Ps. The WAN circuit is 500M/1G burstable. My wired speeds are consistently 600/800+ up/down and my wireless throughput is at most ~150M down and ~450 up. There are only 17 active APs at the moment and I am aiming for symmetrical  up/down throughput considering there is no active traffic on the network.

 

Can you guys point me in the right direction on what settings I should pay extra attention to on the controller? Among other things:

  • Enabled the 40Mhz on 802.11a/n/ac and configured the WLANs with AES encryption
  • Controller firmware is 8.5.140.0
  • 2.4 data rates - 1/11Disabled, 12Mandatory, 18Supported, 24Man, 36Sup, 48Man, 54Sup
  • 5.0 data rates - 6/9Dis, 12Man, 18Sup, 24Man, 36Sup, 48Man, 54Sup
    • Disabled non-DFS channel check
    • Selected DCA channels - 36, 40, 44, 48, 52, 56, 60, 149, 153, 157, 161
    • Max power level assignment: +30 / min -10
    • Power threshold: -65

Thanks in advance,

-AT

Let me guess, controller is running 8.5.140.0.
Testing done on a Lenovo laptop and iPhoneX?
I've seen this thread in reddit.

I'd be looking at what is going on at the FW first.

Next, on the switch: Are there any total output drops to the AP ports and the uplink?
