UPDATE: Nov.01/22: The lag, dropped frame, and general performance issues have been resolved some time ago, apologies for not updating sooner!
UPDATE: Nov. 28/21: The lag / dropped frame issue has appeared for us on 2.4GHz devices connected to an AP22.
TLDR: On our network we could find NO ISSUE with the access point or switch; streaming was smooth and connectivity nearly flawless after 4+ hours of continuous testing. (Update: this still holds true after 14 days on 5GHz broadcasts only. 2.4GHz connected devices are lagging/dropping connection).
After reading a few very passionate posts about faulty AP22s and 1930 switches, I became quite concerned as we deploy these to commercial and residential customers.
I finally found myself with some time to stress test this setup and see if I could replicate the issues mentioned in this forum. Here's what I fired up....
Aruba IO equipment:- (1) AP22 and (1) 1930 24G POE switch
- Site running on version 2.4.0, both in standard configuration, web portal controlled, one additional wired VLAN, no wireless VLANs.
- WiFi 6 Multiple Clients Optimization (OFDMA) enabled.
- 2.4 & 5GHz frequencies split by SSID
- 20MHz & 80MHz wide channels.
- DFS channel 132 used on 5GHz.
Router:Netgate pfSense 1100
Client devices:- 2021 Macbook Pro 14" (ax)
- 2x 2021 iPhone13 (ax)
- 2015 MacBook Pro 13" (ac)
- 2014 MacMini (ac)
- 2011 Sony Smart TV (2.4 n)
- Apple TV 4k first gen (ac)
- Canon business class Laser printer (2.4 n)
- Google home minis & hubs (2.4 n)
- 2x iEast audio streamers (2.4 n)
Reports were that while streaming video, the users would experience buffers and drop-outs, and at points the user reported large gaps of zero connectivity (dropped pings) to the gateway & WAN. To address this, I concurrently streamed YouTube Music on two devices, Netflix on the Sony TV and a MacBook, Disney+ on the Apple TV, streamed high quality Spotify to the streamers and submitted multiple random requests to Google Home devices (lights, queries, etc).
I sent print jobs to Canon printer, waited for it to go into sleep mode, tried again. While all that was happening, I surfed the web on the MacMini and MacBook Pro. I also had an old iPhone 6 (ac) on a second SSID that my son was using to stream Youtube at the same time.
While the above was rolling along, I had ping tests running to google and/or cloudfare.
- We experienced no stuttering, lagging or performance issues on any of the devices streaming audio or video.
- The Canon printer worked as intended (it actually woke up from deep sleep wirelessly, which never seemed to work with our UniFi system).
- After hours of tests the worst ping test was a .02% error rate on the '15 MacBook Pro, 0.1% ER on the Mini, and 0% ER on the '21 MacBook Pro. I see no issue with these numbers on a wireless setup.
I'm unsure what else I could do to simulate performance testing, but if someone has a suggestion, I'm game. I'm thinking the issues reported by users are either faulty equipment or unique LAN settings / corner cases that have triggered performance issues.
