You connect a device to the TP-Link powerline adapter via cable or Wi-Fi, internet connection works but it’s intermittent. It could be the powerline adapter or other factors. Please follow the troubleshooting below to figure it out.

End devices means computer, laptop, mobile phone, etc.

Case 1

Step 1

Disable power saving mode (click here).

Upgrade to latest firmware (click here).

Step 3

Contact TP-Link support with the results above and let us know the operating system of your device.

Case 2

Step 1

Login web-based management interface of the wireless powerline extender (click here). Go to Wireless > Settings page, change Channel Width 2.4GHz→40MHz, 5GHz→80Mhz.

Step 2

The problem occurs on 5GHz or 2.4GHz? If end-devices support 5GHz as well, connect to 5GHz to check if it’s better or not.

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.
