What should I do if internet connection is slow when the device is connected to Mercusys Powerline Adapters?

 

Case 1

Step 1

Connect your end-device to the Mercusys by Wi-Fi without doing any high bandwidth activities and test the speed Speedtest® (www.speedtest.net). Take screenshot of test result.

Step 2

Check wireless link speed (Skip to next step if you don’t know where to find it). Take screenshot of test result.

For Mac OS

Make sure you select network utility. Select Info tab and choose Wi-fi (en0 or en1) on the drop-down options. Please note that the Link Speed is your wireless connection speed. In this example, my connection speed is 450 Mbit/s (Mega bits per seconds).

Step 3

For 2.4GHz, change the Channel (channels 1, 6 and 11 are generally best, but any channel can be used, please try a few more channels). A wireless channel determines which operating frequency will be in use. It is not necessary to change the channel unless you’re noticing interference problems with nearby wireless networks. 

Step 4

Contact Mercusys support with the above results and let us know the number of your end-devices and their operating systems.

 

Case 2

Step 1

Install Mercusys PLC utility. Upgrade the PLC adapter and wired part of PLC Extender to the latest firmware.

If it’s still slow, go to next step.

 

Step 2

Check powerline rate between powerline adapters on the utility. Send screenshot or tell us what it is.

 

Step 3

a. Connect only one end-device to the Mercusys via cable, and test the speed Speedtest®(www.speedtest.net)three times without doing any high bandwidth activities like P2P download. Take screenshots.

b. Connect the same end-device to your router and test the speed in the same way.

 

Step 4

Check wired link speed of end-device (skip if you don’t know where to find it).
