I have a couple of users experiencing such bad VOIP performance that we've had to switch them to Ethernet for now. Their speed tests always show a jitter of 50-60 ms.    We're all using the same WiFi adapter with the same driver version, running the same version of Windows, and connected to the same network and access point. Network traffic isn't particularly high at the moment. We have two 1Gbps internet lines connected to two MX devices. Since my connection isn’t affected, I doubt it’s a network-wide issue.   compassmobiletree The high jitter persists regardless of their location within the building, so I don't think it's related to their local access point (I rebooted it just to be sure).   Any suggestions will be appreciated Thanks in advance High jitter on WiFi can sometimes be caused by interference or hardware issues. Try updating the WiFi adapter drivers, testing with a different access point or band (2.4GHz vs 5GHz), and checking for background apps using bandwidth. If the problem persists, a USB WiFi dongle or continuing with Ethernet may be the most reliable solution.       ... View more
