When you find the internet speed from Deco is below expected, please refer to steps below to locate the problem and troubleshoot according to the corresponding suggestions.
Notifications before we run the speed test:
1. Please make sure Deco, Ethernet cables and the testing PC are all 1Gbps (Gigabit) supported, not to mention the broadband connection. For example, Deco E3/E4/W2400 are fast Ethernet ports(10/100m/s).
2. Most of the time, the speed from satellite Deco nodes are less than main Deco, especially when they are not using Ethernet backhaul.
3. If you are using a wireless device to test speed, make sure the wireless device is 5Ghz supported and capable of reaching high speed. Some old laptop's Wireless Network Adapter is not able to reach high speed.(Please Turn off the low power mode if you are testing speed over iPhone)
Methods and Steps to verify speed:
1. Use Ookla Speedtest App or https://www.speedtest.net to measure Internet speed. The speedtest on the Deco APP is only for reference.
2. Verify maximum broadband speed by connecting a Gigabyte PC directly into the ISP Modem first;
3. Verify wired speed into the Main Deco after verifying the ISP Modem's maximum speed;
4. Disconnecting every wireless device if you are trying to measure the maximum wireless speed of Deco units;
5. Always reconnect Wi-Fi on your cellphones/laptops every time you perform a speedtest.
Possible Solutions:
1. Remove QoS settings: Deco APP>>>HomeCare or HomeShield>>>Turn off QoS Completely or remove all priority devices and set the max bandwidth at 1000Mbps or higher.
2. Turn off the UPNP and SIP ALG in the Deco app: Deco APP>More>Advanced>UPNP/SIP ALG;
3. Try a few other speedtest servers because some specific servers cannot reach full speed at wireless.
