New homeplug/powerline says it is not detected, when all lights are on

I have recently bought a homeplug to connect to the internet since my broadband is downstairs from my pc. I have plugged in the two homeplugs and connected them to my pc and broadband with a ethernet cable. When i turn on my pc the ethernet light turns on (same for downstairs) but after installing the software and trying to search for my wifi a message pops up saying "The homeplug adapter has NOT BEEN DETECTED. Please check your computer cables". So i did so, i chnaged the sockect moved the ethernet cable to a diffrent slot and still it says it has not been detected. This is very annoying and i really want to get it fixed. Is there a solution? Thanks in advance

Which homeplug model, and what OS do you use?

The easiest way to troubleshoot is to plug them into sockets in the same room that are on the same breaker and then move one to its needed location after you see it works.

Make sure that neither are on GFI (ground fault interrupt) circuits and that neither is on a surge suppressor. You also might check to see if there is updated homeplug install software for your target computer.

Yes, good idea to try it out with your laptop -- no reason to move a big machine around.

Also, try holding the reset button down for a full three seconds allowing the power lights to come on fully, and then add the Ethernet cable.

When you go into your homeplug configuration utility on the computer attached to powerline can you see both homeplugs in the main configuration screen, only one, or none?

If you open your router LAN page do you see any of the homeplugs in the dhcp client list?

So all of the homeplug lights come on green, you have the latest software on your homeplug attached computer, you are not on a GFI circuit or surge protector, and nothing shows up?

My only suggestion at this point is to get the two homeplugs on the same electric fuse/breaker to eliminate all electric circuit variables. Maybe get a friend to bring over a PC laptop to avoid moving the big computer?

Just plug them into wall sockets in the same room -- they will be on a single circuit.

It is usually best to let things sit a while anyway when they aren't working -- often the next day everything just seems to work. Happens to me all the time.

I actually have a day of online training tomorrow so I probably will be around most of the day.

Hello again, i was just wondering how puting my homeplug in the same circuit and pluging it into a diffrent laptop help me fix my problem with it in my pc.

Ok shall do that in a bit.
