During important video calls my video stutters, sometimes drops. On WiFi.

WiFi is always vulnerable to noise, roaming and client density. For people in calls daily, an Ethernet cable is the cheapest reliability jump available.

Try this first

1. 1Compare 5-minute windows on WiFi vs wired. On Windows: 'ping -t office-fileserver' or 'ping -t 8.8.8.8' over WiFi, then over cable. Packet loss or latency spikes on WiFi show up here.
2. 2Use a short Ethernet cable to the switch or router. With a dock: make sure the dock's Ethernet port isn't routed through DisplayLink, otherwise it sits on USB-2 and gives you nothing.
3. 3On modern laptops without Ethernet: a USB-C to gigabit Ethernet adapter is around 20 euros. Realtek chipset works out of the box, driver from Windows Update or Apple if needed.
4. 4Disable WiFi when Ethernet is up. Otherwise Windows sometimes picks WiFi for some sessions and you get mixed latency. Device Manager, WiFi adapter, Disable, or toggle in Settings, Network.
5. 5For people who can't sit at the desk edge: WiFi is fine as long as signal stays above -65 dBm and you're on the 5 GHz or 6 GHz band. Check with 'netsh wlan show interfaces'. Below -70 dBm causes stutter.
6. 6In Teams or Zoom: enable 'Hardware acceleration for video' in settings and use HD instead of FullHD outgoing if bandwidth is the issue.
