Initial Cisco C9115AX Testing

Cisco Catalyst 9115AX 80 MHz Channel Width

With a brand new Cisco Catalyst 9115AX access point in my hands, it's time to start testing. Before we begin testing Wi-Fi 6, I had acquire a compatible client.

So after an Amazon order and waiting two days, I am a proud owner of an unlocked Samsung S10.

To be fair, testing Wi-Fi 6 with only one client is kind of pointless. The purpose of Wi-Fi 6 is to bring efficiency. There isn't much to efficiency to be made when it's a single device on the Wi-Fi network.

But just to take a look at it operationally, I joined the Catalyst 9115AX access point to a Cisco 3504 wireless LAN controller (WLC) running version 8.9.100.0. This is the minimum version required to run a Catalyst 9115AX on a WLC.

Here are my results after installing a local speed test server on CentOS 7.

Run	Down	Up	Ping	Jitter	Channel	Channel Width
1	391.91	454.63	3.69	1	36	40
2	368.14	443.3	3.3	0.23	36	40
3	292.08	426.95	3.74	0.73	36	40
4	366.8	428.19	3.47	1.2	36	40
5	661.06	700.46	4	1.39	36	80
6	595.42	741.73	3.65	1.14	36	80
7	604.71	710.91	3.96	0.88	36	80
8	667.49	711.53	3.52	0.82	36	80

I plan on doing a more structured test with an additional client, once I receive it. I'll share other data as well such as configuration, setup of the speed test, use of iPerf, and other applications.
