There are different situations in relation to the slow speed issue, please refer to the steps below to locate the problem and troubleshoot according to the corresponding suggestions. 

 

Step 1. Figure out whether you’re experiencing slow speed problems on multiple devices.

If only a specific device has the slow speed issue, simply turn the device’s Wi-Fi off and on again. If that doesn’t work, try rebooting the device.

If it’s a computer, usually uninstall and then reinstall the driver of the Wi-Fi network adapter will make sense. You could refer to the manufacturer of the adapter if don’t know how to do that.

If multiple devices suffer from the slow speed issue, read on!

 

Step 2. Identify the Deco is a 100Mbps product or a Gigabit (1000Mbps) product.

It’s suggested to go to the official website, and then go to the specification page of the Deco model to check this information.

Please note if the Deco model is a product with 100Mbps Ethernet ports, the maximum speed of the Deco system is 100Mbps only. If you order an internet service with a bandwidth of over 100Mbps, it’s recommended to purchase a Deco model with 1000Mbps Ethernet ports.

 

Step 3. Confirm if the main Deco gets the expected wired speed.

1)       Connect a PC to the Deco by an Ethernet cable, then open the browser and go to Speedtest® to test the internet speed.

2)       Disconnect main Deco from the modem. Connect a PC to the same Ethernet port (the port that main Deco ever connected) on the modem with the same Ethernet cable. Then open the browser and go to Speedtest® to test the speed.

Compare the two speed test results.

a.       If the speed test result is slow when the PC is connected to the modem, restart your modem. Restarting your modem can sometimes fix connectivity issues and improve the performance. If it doesn’t make sense, it’s suggested to contact your ISP.

b.       If the speed test result is normal when the PC is connected to the main Deco, move on to the next step.

If not, refer to Case 1.

 

Step 4. Connect the same PC to the slave Deco units one by one with an Ethernet cable, and go to Speedtest® to test the speed of each slave Deco.

If a certain slave Deco experiences slow speed in this case, please refer to Case 2.

If the slave Deco gets a normal wired speed, move on to the next step.
 

Step 5. If the wired speed from the Deco is good but you’re still experiencing slow Wi-Fi speed, please refer to Case 3.

 

Case 1:

1.       Disable QoS features on the Deco app, set Application Priority as Standard and clear all High Priority settings.

2.       Reboot the main Deco and test the speed again.

 

Case 2:

1.       Move the slave Deco closer to the main Deco, ensure there are no/fewer obstacles between the main Deco and slave Deco, then we can test if the slave Deco can get better speed.

2.       If the Deco still experiences slow speed, reboot all the Deco units for a try.

 

Case 3:

1.       If you want to make a speed test on a mobile device, we recommend to run the Ookla speedtest.net app to check the internet speed. To ensure you’re connected to the nearest Deco when doing a speed test, please turn the mobile device’s Wi-Fi off and on again after it moves to a new location.

2.       If the client experiences slow Wi-Fi speed issue while connected to the main Deco, reboot the main Deco for a try.

3.       If the client experiences slow Wi-Fi speed issue while connected to the slave Deco, move the slave Deco closer to the main Deco and ensure there are no/fewer obstacles between the main Deco and slave Deco. If it doesn’t make sense, reboot all the Deco units for a try.

 

If the above suggestions can’t solve your problem, it’s suggested to contact TP-Link support.
