I can't get Wi-Fi in my bedroom because its not in range?

My house is quite big and my tiscali modem is to far out of reach of my bedroom, and i need the internet for my xbox, laptop and iphone is there any way i could get Wi-Fi

You might need a stronger internet router or something that will make your signal stronger.

My Internet connection in my room was like totally sh#t, because of things in the way, the fridge was in between my room and the router which made my Internet connection bad we moved it it worked fine, it might be something in the way.

Wrap the Antenna with an iron stick or with aluminum use for cooking to wrap it. It can go further about 5m from the original.

There's at least three things you can do, in order of simplicity:

1. Put up a parabolic shape of tin foil behind the router to reflect more of the signal in your direction.

2. Fit a better aerial from Maplins [1].

3. Fit a wi-fi repeater device nearer your room, such as [2].

Get a pair of powerline adapters, these use the household wiring instead of a long Ethernet cable. You plug 1 adapter into the Ethernet port of the router and local mains socket the other adapter into the distant PC/Laptop/game console and a mains socket. If you replace the distant powerline Ethernet adapter with a powerline Wi-Fi adapter you can create a local hotspot a good distance from the router.
