Symptoms
- Calls sound choppy or robotic specifically over Wi-Fi Calling
- Switching to cellular improves call quality
- Quality is worse when others are using the same Wi-Fi network
- Calls drop when moving around the house
Likely causes
- CommonWeak Wi-Fi signal in the area you're calling fromWi-Fi Calling needs a stable connection, and being far from the router weakens call quality.
- CommonNetwork congestion from other devicesStreaming, gaming, or large downloads on the same network can starve call quality of bandwidth.
- PossibleRouter quality of service settings not prioritizing voice trafficSome routers can be configured to prioritize voice calls, which isn't set up by default.
- PossibleISP-level network issuesAn unstable internet connection at the source can affect all internet-based calls.
- Less commonPhone switching between Wi-Fi networks mid-callMoving between different Wi-Fi access points, like in a mesh system, can briefly disrupt calls.
What to do
- Move closer to the Wi-Fi router during calls.
- Pause other bandwidth-heavy activities on the network, like streaming or large downloads.
- Restart the router and modem.
- Check if your router supports Quality of Service settings and prioritize voice or call traffic if so.
- Test call quality on cellular data instead to confirm the issue is Wi-Fi specific.
- Try connecting to a different Wi-Fi network, like a mobile hotspot, to compare.
- Restart the phone to refresh its Wi-Fi Calling connection.
- If quality remains poor on a normally stable network, contact your carrier or ISP to check for further issues.
When to call a pro
If Wi-Fi Calling quality stays poor on an otherwise stable, fast internet connection, contact your ISP or carrier to check for a deeper network issue.
