Re: Wireless advice/help please
You will need a wireless router obviously.
If you want to connect the desktop wirelessly then you'll also need a USB adaptor or PCI NIC for that.
If you're happy to continue connecting the desktop with a cable then the wireless router will have ethernet ports that you can plug a CAT5e cable into.
