|Ok, your post is a little unclear.|
Does your friend already have a wireless network configured and working? If not, do you?
If neither of you does, one of you would need to purchase a wireless SOHO router and then create a WLAN (Wireless LAN) and both of you would then join it.
It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.
