Hi, here is my connection, but it fails to work... the router can't get IP address from ISP.

Line socket -> 1st homeplug -> powerline -> 2nd homeplug -> WAN port of router

This setup is working:

Line socket -> WAN port of router

So I wonder, technically speaking, does powerline work on WAN port of our router? Why it doesn't work for me?

PS: My ISP doesn't require any cable modem, just a wall socket.


Thanks!!

It should work. What is the model of your router?

Does your ISP have any limitation on the number of mac addresses you have. These devices still send packets out with macs on them. Many have a special utility software to configure them that uses only mac addresses. Even though the devices will never actually send data to the internet or even attempt to get a IP address they likely are sending quite a number of frames of data containing a mac. If for example you are on say one of the systems colleges use that lock the port to whatever mac it sees first then you could be having issues.

In general I would say you could use these device on the wan because most people would use them between a cable modem and a router. It is pretty easy to get a cable modem to take the mac you want and other mac addresses would just be ignored. When you connect it to something else it becomes much more troubling. I do know they almost immediately disable a port on a commercial cisco switch that has port security active. I never really gave it much thought until now as to why it did that.

I tried again today and it is working, I am not sure why, but it seems that the step is important.

Device should be connected in this sequence:

1. 1st Homeplug
2. 2nd homeplug and wait for while
3. Power on the router
