Wireless Card (UK)

HI first post here, so fingers crossed I'm asking in the right place.

I'm looking for advice on buying a wireless PCIe card, ie what should I get.

I'm a student living in a shared house and I'm currently connecting via a very long cable which is forever being unplugged.

I'd like to get something that's not too expensive (ie under £30) and antenna that's attached by a cable.

Thanks.

Just get a powerline adapter. Other than that just have a look on Amazon or something..
