A Wi-Fi connection that drops during a call can have several causes. Start by checking whether the problem follows one device, one room or the whole home. That pattern gives you a useful next step before you buy equipment or change router settings.
Make one change at a time. After each change, repeat the activity that usually triggers the interruption for long enough to see whether it returns.
1. Check what actually disconnects
When the next interruption happens, look at your device’s Wi-Fi connection and try opening two unrelated websites.
- The device leaves the Wi-Fi network: continue with the checks below.
- Wi-Fi stays connected, but neither website loads: use our Wi-Fi connected, but no internet guide.
- Websites load, but one app or call fails: check that app’s service status and troubleshooting advice before changing your network.
Write down the time, device, room and symptom. An occasional dropped call alone does not establish that Wi-Fi disconnected.
2. Choose the next check from the pattern
Test a second phone or laptop on the same Wi-Fi while the problem is happening.
- Only one device drops: restart that device, reconnect and check its software. See section 4 for Windows checks.
- The connection drops only in one room: compare the same activity near the main router. See section 3.
- Several devices drop together: check the shared equipment and service. See section 5.
- The problem appears when moving between rooms: note where it happens and whether you use mesh units or an extender. Test while staying beside the main router before changing the mesh configuration.
These observations narrow the investigation; they do not prove which component is faulty.
3. Compare the problem room with the main router
Use the affected device near the main router for a comparable period. Then repeat the same activity in the room where it usually disconnects.
If the connection stays reliable nearby, start with coverage and placement. Microsoft’s home Wi-Fi guidance explains how distance, obstacles and interference affect the signal.
Check whether the router is hidden in a cupboard or surrounded by large obstructions. If your network has separate 2.4 GHz and 5 GHz names, compare them in the problem room. The result is a useful clue, rather than a reason to force every device onto one band.
For the next steps, see weak Wi-Fi in one room.
4. If a Windows 11 laptop keeps disconnecting
Save your work, restart the laptop and run the Network and Internet troubleshooter in Get Help.
If the problem continues, have your Wi-Fi password ready. Open Settings → Network & internet → Wi-Fi → Manage known networks, select your network and choose Forget. Reconnect with the password. Ask IT first on a managed work or school device.
If drops happen after sleep or mainly on battery power, check the Wi-Fi adapter in Device Manager → Network adapters → Properties. If a Power Management tab is available, try clearing Allow the computer to turn off this device to save power. Some adapters do not expose this option; skip it if absent. This change can increase battery use, so record the original setting.
Check Windows Update and your laptop manufacturer’s support page for the correct Wi-Fi driver. Avoid third-party driver download tools. Microsoft’s troubleshooting guide covers these steps and explains why network reset should come later.
5. If several devices disconnect together
Check your provider’s outage information using mobile data if necessary. Note whether the router’s lights change or it appears to restart when the drop occurs.
Restart the modem and router using the provider’s or manufacturer’s instructions. Warn other users first: their connection will stop temporarily. If the units are separate, allow the modem to reconnect before starting the router. A combined unit only needs its own restart procedure.
Do not press the recessed Reset button. A factory reset can erase your network settings and is different from restarting the equipment.
If you have a suitable Ethernet cable and a computer with an Ethernet connection, compare a wired connection to the router during the problem. Stable wired access with failing Wi-Fi points toward the wireless path. If both fail, investigate the router, modem and service rather than treating it solely as a coverage issue.
6. If an iPhone or iPad keeps losing the connection
Restart the device and compare its behaviour near the router and on another trusted Wi-Fi network. A problem that follows the device across networks needs a different investigation from one that occurs only at home.
Check for device software updates. If several Apple devices have trouble on the same network, also check the router manufacturer’s firmware guidance.
Apple’s Wi-Fi troubleshooting instructions include additional checks. Leave Reset Network Settings until simpler steps fail: it removes saved Wi-Fi networks and passwords, as well as other network settings. Consult IT first if your device or connection is managed.
7. Escalate with useful evidence
If the drops continue, give your provider or technician your notes: affected devices, times, rooms, whether the Wi-Fi connection disappeared, and the results of the nearby-router and wired tests.
Mention any recent router, extender, device or software change. If a restart helps only briefly, include how long the improvement lasts.
Before spending money, read what to check before buying a new Wi-Fi router. Choose replacement equipment only after you have evidence that it addresses the problem you observed.
