Powerline help

[Sulfrex]

Hey,
So basically I've just moved into a new student house, got virgin in the house, 60 down package.
Now the problem is, at home using the same powerline adaptors I was getting the full 60 down. Here I am only getting 15 with dropped connections a lot of the time. Sometimes only getting 0.5 down.

Any ideas how I can improve this, so it at least dosent drop connection?

I am on the third floor of the house, if that makes any difference.
The powerline adaptors I am using are; tp-link TL-PA411

Thanks

I am the only person in the house with powerline, and both are plugged directly into their own wall sockets. The house is quite big, is there a way to boost the signal between the 2 adaptors?
I have not tried using it in a different room yet but I will give it a go now.
This morning I cannot get it to connect at all, even after several resets of the router and powerline. I am getting an unidentified network instead of the network I should be connected to.

Thanks
