EAP670 packet latency an jitter
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
Change eap225 to eap670 and see a huge latency and jitter with some device. With eap225 on wifi AC was perfect...
Eap670- disable roaming,disable mesh- got a little better . Enable/disable "Unscheduled Automatic Power Save Delivery" and OFDMA - without result. Using channel 48 with width 160MHz.
Disable all off these,change channel number and channel width - no change. I see a icmp ping drift from 3 to 30ms on laptop with Intel AX210. Mobile phone - 20 to 300ms. Ping from Gateway to eap670 - always 1ms. And sometimes laptop show 100ms. Laptop and phone are located 5 meters from the access point.
On channel 48 I download a file to a laptop at a speed of 870 Mbps, and on channel 36 - no more than 600Mbps...

Hi, did this latency issue cause your network drops or slow speed?
How did you power the EAP670?
Maybe you can change a short cable to connect them for testing.

I mean slow speed without drops. Eap powered with poe-injector tl-poe160s now. Trying to change with power supply - the same result. Cable is about 5 meters and it is OK, because ping from gw to point less than 1ms without drift.
Mobile phone are particularly affected.

Phone location - static in one place.Ping on free network without any traffic(no any other WiFi client are connected to eap670 and no another traffic from the phone except ping).
Also at 48 channel the speed is high then at 36 channel.

Connect to the same Organization eap225-outdoor v1 - no issue packet latency and jitter with the same setting. But when clients connect to eap670, the problem reappears.

Hi @g2_ufo ,
Did you get the solution to this?
Facing the same issue with EAP265 HD and no luck yet.

Can we confirm the signal strength of the client you are testing with? Before you do the speed test?
Also, what's the RX/TX numbers of the tested client? During the test.
We need to know those numbers before we make a brash decision on this AP.
Also there is a new Beta firmware out, go ahead and upgrade and retest, BUT get those numbers I request above before retesting.
Also, can you confirm that your Intel wireless card has the newest firmware loaded FROM the intel site and not from windows update before the retest.

This latency to reach the AP is unacceptable, and If I chage the AP to a different brand with same config the issue just desapear.
