wireless router

[deggers316]

my friend has his comp on an extension socket he's only pulling 6 mb out of 10mb download (showing in the router config:)
orange support say if he was into the master socket he would pull 10mb
the guy also suggested plugging the router into the master socket and go wireless then he would also get 10 mb that way bypassing the long extension cable
is he right?
i know i need a pci wireless card but dont want to waste money if you think this will make no difference

buy a USB wireless router dongle for
about £15.00.
plug your router into the master phone socket
and it should pick it up.
