BTW guys,
I bought my router around January the 9th or so, it came with the USB adapter for so that you don't have to but it seperately which would cost like £40 more then usual.
So like I said it came bundled, the I bought it for £54 I think, can't seem to find the receipt at the moment.
Compared to the other VERY expensive wireless routers out there that cannot get the job done, the Linksys exceeds all expectations!
Please check the following links, this is all you need, I know its going past what you want to spend, but have a look, PCWorld always have these routers on sale bundled with the USB adapter.
The following website is microwarehouse:

There are two of the USB adapters for the wireless router, one comes with the ''speedbooster'' technology, I have no idea what the benefits are, but it was bundled with the Linksys I got.
I think I put the power up too much
