Need help with wifi networking setup

[OkarasChimera]

Been running my laptop as a file hoast for movies and music for a while and after upgradeing to more bit rate intensive movie files ".mkv" and discovered an annoying fact. After opening up task manager I am using a massive 1MBPS of the 200MBPS rated on my wifi hub. It is the one my internet service provider given me over 4 years ago and I am wondering if anyone has any advisements for newer hardware both wifi hub and computer pci/usb based wifi connections.

 

Wired connections would fix it prity easy but I don't want to lay cables all over my house and the wireing in my home is too old for mains line based networking. I run 2 computers on the networking along with a ps3 at peak times.

 

Budget is £150 for both items combined though I am willing to stretch to £200 if it is worth the extra costs.

 

Any help would be much loved
