Hi! I'm new to this site and a relative novice in the world of computers but I am having a very frustrating network connection problem.

Laptop: Dell XPS ultrabook running windows 7

Modem: Telstra technicolor TG797n v3

 

Bit of background: I am a student and i live in a fully detached building (my room) on my parents' property. The modem is located in the house building. My room is located approximately 25 metres from the modem and my room is constructed of stone walls with a galvanised iron roof and thus is totally impervious to the wifi signals being transmitted from the modem (i have tried multiple different wifi range boosters, changing the position of the modem in the house etc nothing worked).

The house and my room are on the same power circuit so i purchased some ethernet over powerline adapters, which solved my connection problem and i have successfully received a strong, reliable wired connection in my room for the past 6 months. **note: the 'receiving end' adapter is ethernet, not wifi, so my connection is always a wired connection in my room to only one device at a time.**


Recently however, my internet connection via these adapters to devices located in my room has suddenly died. The home network appears on my laptop as an 'unidentified network' and when i troubleshoot the problem i receive the error message 'local area connection doesnt have a valid ip configuration'. I received the same error messages when i plug the adapter into my playstation 4 in my room (suggesting it is not an issue with my laptop).


interestingly, if i then bring the adapter from my room in to the house building and plug it in to the wall and connect it to my laptop, i receive a perfect ethernet over power connection (don't worry i am sure it is not the wifi signal reaching my laptop as i have disconnected from the wifi). To me this proves that it is not an issue with the laptop, or the playstation 4, or the ethernet adapters themselves. It is as though the powerline running between the house and my room is causing a network connection error.

I have followed the  instructions for this networking sub forum, and downloaded minitoolbox and ran the system diagnostic tool, the results of which are below (run on my laptop whilst connected to the ethernet adapter in my room).

You are using the same laptop to connect inside the house and inside your room? The fact that the powerline ethernet adapter works inside the house and not inside your room would seem to indicate your assumption is correct -- the powerline running out to your room seems to be the issue.

 

Short of hiring an electrician to trace the problem with the electrical line, try following these steps to see if they help resolve the issue:
