Thank you both.
The automatic set-up instructions appear to say choose the first option to set-up a wireless connection for the computer but choose the USB flash drive option if other devices are to be added. I want a wireless connection for my desktop with printers, scanner and LCD tv linked. It's a Sony PC, with 2 USBs and a memory stick slot. And I was wondering what the difference is between a USB and memory stick, since I'm going to have to buy one or other before I begin the set-up. My other question was about storage capacity.
Maybe I should simply get an in expert!
