Hi
neupane00 and welcome to the Forum.
All X10 signals work almost the same way.
The socket rocket gets its signals through the power lines.
If yours worked nearby and sporadic at a new location then a phase issue comes to mind first - the signal has to cross the other side of the panel to reach its destination, phase coupling would be considered.
There is allways noise makers and suckers - electronic equipment that is weakening the X10 signal the socket rocket or even any other module on the same circuit.
Start here to help diagnose your problem as well as a leaping point for help in X10.
http://www.x10community.com/forums/index.php?topic=7951.0Try unplugging things like cordless phone, cell phone, laptop chargers packs, or Large LCD TV or other possible noise makers. If the socket functions better then filters should be in list of things to have. Mapping your home curcit is also something to keep in mind, knowing where every single branch on your home wiring is going and what it is attached too is essential and I do mean everything, from lights(CFL's maybe), equipment, fixtures, HVAC and so on. Knowing where everything is in your network will make finding problems very essential.
The X10 world is no where near perfect, so is many other brands of automation out there not as bad at times thou. For the price and the fun to had, there is no comparison by far but it will need to be babied a bit or maybe allot depending on your outlook for automation. Don't ever give up, many here did or came close too but in the end like me, we just cant get enough of this stuff now and all we can do is try to help and convince you it does work and yes its a blast.
Good luck in solving the problem, you can be assured for help when needed here in the forum. Do some Advanced searches and sit back a read and fill the mind with X10 knowledge, its geeky kinda but damn cool at the same time.
cheers.
