|The best (easiest) way to set this up would be to buy a wireless SOHO router and have that connected to the internet in your home. Then, connect all other devices (wired or wireless) to it.|
Internet >> SOHO Router >> clients (wired/wireless)
You're attempting to use your computer to distribute the wireless network and that would require two network interfaces on the computer and the use of ICS. This is clumsy, a pain in the butt to setup and simply put, not the best way to do this.
You don't specify how your computer connects to the internet (ie: wired or wireless) and that would be helpful info that we could use in order to assist you.
Please explain how you're presently connected to the internet and what equipment is used to provide that connection.
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.
