TRENDnet TPL-401E, Quick Installation Manual

1. 

1. 

I have verified that my Powerline device is connected to my workstation, but I cannot 

detect other Powerline devices.  What should I do?

1. Verify that you are using Cat. 5, Cat. 5e or Cat. 6 Ethernet network cables for each 

TPL-401E adapter.  

2. Verify that the power outlet of the TPL-401E adapter is plugged into is on the same

electrical system and/or circuit breaker box.  

3. If you are still not able to establish connectivity after performing the above steps, please 

reset both of the TPL-401E adapters to factory default. The default network name/key is 
“HomePlugAV”. The Reset button is located on the bottom of the TPL-401E.

1. With a pin or paperclip, press and hold the reset button for 1 second and release it. 

The LEDs will turn off and turn back on. 

2. To verify connectivity, the PL LED will become solid when the powerline adapters 

establish connectivity. The TPL-401E powerline adapters must have the same 
network name/key in order to connect to each other. 

Note: If you have problems resetting the device, unplug the powerline adapter(s) from 
the power outlet, wait 15 seconds and plug the adapter(s) back into the outlet, then 
repeat the reset procedure.

2. I can detect my Powerline devices on my Powerline network, but I cannot connect to the 
Internet.  What should I do?

Assuming that the Powerline network is connected to a router:

Make sure you are not connecting the device into a surge protector or power strip.  

2. Make sure that your Router is connected to the Internet and one of the Router's LAN ports 

is connected to the TPL-401E's network port). Check both TPL-401E and the router's 
network port LED for positive connection status.

3. Make sure your computer's TCP/IP settings are set to Obtain an IP address 

automatically (see the steps below).
