Please could someone tell me the best way to make full use of my broadband for gaming. I have read some threads that say to have a direct cable connnection. I currently have a cheap tp link usb wireless. My router is downstairs so I can't plug it into my computer. Do I get a second router or an extender? Some threads suggest an extender but doesn't this boost the signal using wireless so how could that be better than a usb wireless stick? Thanks.
