Model: EAP670  
Hardware Version: V1
Firmware Version: 1.0.12

Hello,

 

I recently "upgraded" my home network from EAP245's to EAP670's primarily for in home wireless VR streaming. This use case is highly sensitive to network latency and variance so I use a variety of tools to keep an eye on it while streaming. After the upgrade, I noticed that both latency and variance increased with the supposed upgrade. Latency has gone from ~2ms to ~5ms, what was ~0ms of variance has gone up to ~5ms (occasionally spiking all the way up to 8ms), and whereas with my EAP245's I suffered 0 dropped frames, with the EAP670's I'll drop a good handful.

 

So worse performance all around excluding throughput.

 

Running with a controller and I still have 1 EAP245 on the network that I used for these comparisons.

 

Is this due to an immature firmware or something? Or mis-configuration? Anything I should look into?

 

Thanks!

 

Edit 1: After running the AI optimizer variance has improved but is still not great and latency remains ~double than what it was with the old EAP245's. ~5ms

Edit 2: Some additional info:
 

Controller: OC200 v1.0

Controller Firmware: 1.26.3 Build 20230906 Rel.36269

OLD Controller Firmware: 1.26.3 Build 20230906 Rel.36269

Current Controller Firmware: 1.28.1 Build 20231117 Rel.58466

 

Someone on Reddit reported that they had issues with that Sept OC200 firmware, so I upgraded to beta. Will test in a bit.

 

 

Router: ER605 v1.0

Router Firmware: 1.3.1 Build 20231207 Rel.61384

 

EAP: 3x EAP670(US) v1.0 (actually v1.26, but reports as v1.0 which doesn't exist)

EAP Firmware: 1.0.12 Build 20230922 Rel. 53972
 

EAP: 1x EAP245(US) v3.0

EAP Firmware: 5.0.6 Build 20220429 Rel. 44315
 

Fast, AI, and Dual 11k were all disabled. I just enabled fast and Dual 11k and tested: avg latency dropped to 4ms from 5ms, but jitter is still high and avg is still much higher than it was with the old APs.

Take a look: How to optimize wireless performance of EAP products

And enable Fast roaming, band steering, and 802.11r for testing.

Thanks  @Virgo for taking the time :)

 

I've gone through that guide and followed your advice, no major change. I have it down to ~4ms but with unacetpable latency spikes up to 10ms occasionally occurring accompanied by frame drops while streaming in VR. Happens regardless of which new AP I'm connected to.

 

I've also experimented with some of the per AP settings such as QoS No Acknowledgement and OFDMA, neither of those had any impact.

 

I haven't had time to disconnect all but 1 AP yet, but will try soon. Maybe this has something to do with running in a mixed AP environment? I still have 1 EAP245 on the network for a portion of my house where I generally don't intend on streaming VR from.

So it appears that the EAP670's just have higher latency than EAP245's.  That's unfortunate.

 

I've followed all guides, contacted support and followed all recomendations, followed all advice I could get on the forums and then net result has been -1ms to my latency taking it from 5ms to 4ms. Still up from the 2ms I get with my EAP245's. 

 

If a firmware update ever does fix the issue I'll come back and update here.

 

If latency is critically important for your use case, I'd consider another model.

Just to circle back around... Have you confirm the signal strength of your test device AND the band it was testing on, during the test?

  @jasonridesabike 

 

Have we also confirm the test device was connected to the 670 during the test also?

I've tested with only the 670 ap connected and ensured that my device is connected on the 5ghz band. I have a grand total of 12 AP's of various models to test across 2 sites, home and my company. It really does seem like the 670's just have a latency issue.

Did you try to create 2 different SSIDs? one for 2.4GHz and one for 5GHz radios. Also, disable band steering, airtime fairness and mesh (if you don't need it). Try also to replace the ethernet cables.
