Powerline network adaptors
posted by Sam Edney on Dec. 8, 2014, 2:40 p.m. (1 day ago)
I've had some strange issues with our home network recently; IP address conflicts, a different public IP sometimes (even though I should have a static one), loss of internet, lost connectivity to the router etc. While trying to figure out what was going on - I refreshed my router's web-interface via it's IP address. To my surprise, I found myself looking at a BT Home Hub (no password prompt) but on the same IP as my own Router. Im not with BT and I dont have a HomeHub.

To cut a long story short, using TPLink Powerline adaptors are not encrypted by default. Installing them was making my home network available to my neighbours - and theirs to mine - since they had the adaptors too. I was able to browse their entire home network, see their printers and media server.

Our houses are only around 5 years old, fully detached and we have had no issues with our electricity supplies.

Many posts on the web say that a fusebox will filter out the signal and prevent cross-over. This is definitely not the case!

For now I have removed the adaptors but will replace with some that offer encryption soon.
