I got my folks a pair of TP Link powerlink 500mbps adapters about a month ago which have been doing their job well until the weekend just gone where I got called to go fix their setup. I found the adapter had merged the network with one from another house which is at least 3 semi-detached houses away (They know all their immediate neighbours).
If you install your own powerline network ensure you use the configuration utility to change the network name your connecting to do something rather unique rather than just using the default else you might end up on someone elses network. It seemed to be the case if you set the network name the same as was being used by an existing adapter then they would automatically pair up in other words no only does the network go much further than you would hope its also secure as a swiss cheese!
