R6400v2 Choppy Calls & Some Devices No Connection
My router is about 3 years old. Since COVID, I have been working at home and noticed I have choppy audio in/out on Teams calls on approximately 1 of every 10-20 calls. I have run speed tests while bad...
Does it happen if you're hardwired into the router?
The goal is to determine if its a wireless issue, a router issue, or just a teams issue.
What firmware are you on?
What modem/gateway is it connected to?
You got me thinking. On my lunchbreak I ran some tests using the following websites. The ring central doesnt have download/upload speeds based on the test I ran. I noticed similar jitters in the two different tests.
I not a wifi guy so I dont claim to know how good my tests were. I ran back to back tests. My guess is the jitter on wifi is causing the issue based on a REALLY small sample of tests. Doing reading it looks like jitter greater than 3ms can start to cause prolems with >20ms breaking the audio. I will try and run these tests when audio starts breaking again but the timing is really bad since I am usually in important calls when it starts breaking up.

What should be my next step?
Also my router has the current firmware.
What actual firmare version is it?
What modem/gateway is it connected to?
Do your testing on the 5ghz and not 2.4ghz. 2.4ghz is more sensitive to interference.
- The R6400v2 firmware is 1.0.4.106.
The modem is a Arris SB6183.
I’ve been running 2.4ghz. I can do not ex testing on the 5ghz when I am working at home again on Friday (have to be in the office Tu-Th). I’ll post notes then.
