Then, I can just plug in more powerline adapters to access the internet. My assumption is that the 1st powerline adapter connected to the modem will spread the internet throughout the building. So let me clarify how I've set up my powerline:ġst powerline adapter - connected by cable to the modem PPPoE connection (WAN connection)Ģnd powerline adapter - connected by cable to first router on the first floor (WAN connection) Internet worksģrd powerline adapter - connected by cable to second router on the second floor (WAN connection) Internet doesn't work, fail to authenticate username and passwordĤth powerline adapter - connected by cable to laptop, cannot access the internet too, wrong username and password when I tried connecting through PPPoE connection, though the username and password I entered are correct But, I don't quite get what you are saying.

The question is: whether the model that I bought can only connect up to two powerline adapters? And if more than 2 powerline adapters can be connected, how to troubleshoot it? The error shown for the wifi router is also fail authetication due to incorrect username and password. The error shown for the laptop, is incorrect username and password (I use PPPOE connection). I've tried connecting the 3rd powerline adapter to my laptop or to my wifi router and still no internet connection. I followed the instruction on the TP-Link website, where I just need to plug the 3rd powerline adapter to the socket and press the pairing button for 1 sec on 1st powerline, then press the pairing button on 3rd powerline adapter for 1 sec. Very easy just plug and wait.īut when I tried to install the 3rd powerline adapter, I have no internet connection for the 3rd powerline adapter. IThe first time I tried installing just 2 pcs of powerline adapters, 1 to the modem and another to a router or to my laptop, there is no problem. In total, I have 4 pcs of powerline adapters. Each set containing 2 pcs of powerline adapters. I've recently bought 2 sets of TL-PA4010PKIT.
