no it's not
the "software" is just a muppet installer that configures the settings
I assume orange isn't good (weak signal?) - so it's more likely to be the position of the router.
wireless is basically rubbish - the number of factors it "could" be is huge,
in effect you need to imagine looking through the floor and walls and "seeing" the router - you can't see through metal
and microwaves, TVs, fridges etc will "blur" the image
try moving the router round - most people want it as out of the way as possible - not good for a transmitter
