Okay, I understand that you are experiencing consistent packet loss every 5–10 minutes during calls while using your Deco Mesh system in Access Point mode, even though your speed tests are strong and the issue only occurs over Wi-Fi (not when wired to the satellite units).
Here are some steps you can follow to troubleshoot and hopefully resolve the issue:
1. Compare with a Direct Connection:
• Connect your PC or laptop directly to your main router or modem (bypassing the Deco units) to see if the packet loss persists. If it does, the issue may be with your ISP or the main router.
2. Check QoS Settings:
• Open the Deco app, go to MORE > QoS, and ensure the bandwidth matches your actual subscribed Internet speed. Incorrect settings can cause performance issues.
3. Review Client Device Settings:
• In the Deco app's client list, select your affected device and make sure 'Speed Limit' is disabled and 'Connection Preference' is set to 'auto' (the default).
4. Check Parental Controls:
• In the Deco app, go to the 'Parental Control' section and confirm that your devices are not accidentally restricted by any profiles.
5. Satellite Deco Signal Strength:
• For wireless satellite units, ensure the signal strength is at least 2 bars in the Deco app. If it's only 1 bar, move the satellite closer to the main Deco.
• If you use Ethernet backhaul, double-check the Ethernet connection and ensure 'Ethernet Backhaul' is shown in the Deco app.
6. Wired vs. Wireless Comparison:
• Since you mentioned no disconnects when wired to the satellite units, this points to a wireless backhaul or interference issue. Try moving the satellites slightly closer to the main Deco or repositioning them to avoid walls, metal objects, or sources of interference (like Bluetooth devices, cordless phones, or soundbars).
7. Wi-Fi Band Selection:
• For latency-sensitive activities (like calls), ensure your devices are connected to the 5GHz band, not 2.4GHz. You can check this in your device's Wi-Fi settings or in the Deco app.
• Also, make sure you are connected to the main network, not the guest or IoT network.
8. Additional Tips:
• Since you have turned off beamforming and mesh, consider re-enabling mesh technology, as it is designed to improve roaming and stability between Deco units.
• Avoid placing Deco units in enclosed spaces or too close together. Open areas and proper spacing help with signal quality.
If you still experience packet loss after these steps, please contact TP-Link support and provide the results of the above troubleshooting. This will help us assist you further.
