Can't get a signal in my bedroom

[Gibs960]

So half the time I'm getting about half signal and about 4mb/s download speed, and the rest of the time I can barely get a signal at all. Virgin say there's a problem with the area but the signal is fine in 70% of the house (only the kitchen and my room where I struggle to connect). My step mum doesn't give a **** basically because it's not affecting her - so I wanted to know if there was anything I could do myself. Any help?

Wi-Fi btw in case anyone wasn't sure, I assume most of you understood.

Virgin won't help you here, you either need to move your router or buy a bridge/Wireless Access Point.

If there's something interfering you can always adjust your router settings. @Gibs960;
