I recently bought these wall adapters because I thought my old one that are something like 5 years old didn't work. Seems not to be the case because I'm running into the same problem as before.
Of the 2 adapters the one with all 3 lights (Power, powerline, ethernet) is connected to my computer while the one connected to the modem has only 2 (Power and powerline). I used the ethernet cords that were included with them as well as my old ones but neither seems to make a difference. I've paired them as well but still the same problem. I downloaded the tlPLC Utility program and both adapters are showing up but are showing the same thing regarding the lights. There's a connection still but no internet. When I try to troubleshoot it on my computer's end the problem I run into is "Ethernet 3 doesn't have a valid ip configuration".
