|I think you may be confusing a modem with a router unless we're talking about a combination unit (which are becoming more common) that is a modem, a router and a wireless access point all in one. |
If you could give us the make/model of your "wireless modem for the computer network" we could figure out if it's a modem, a router, or a combo unit. This would help us to advise you on what you'll need to do what it is you wish to do.
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.
