Right now I have a wireless USB adapter. It's connected to my PC and picks-up my friend's wireless network (w/the passwords) and I have access to the internet on my PC.
But I need another device I think:
I want to be able to join his wireless network and have a router with several ethernet sockets so I can connect my PC and additional internet devices like another PC or an internet phone so:
internet my friend's wireless network ME and I have a bunch of ethernet sockets to use.
What device should I buy? What is it called? I want to join a wireless network and then have several Ethernet RJ-45 sockets for devices to connect to the internet.
