If you’re not in mood to read all I have to say, and want just simple plain tips, feel free to skip to the end of post. 🙂
About a month ago, I was trying to set-up ICS (Internet Connection Sharing) between my computer and my wife’s laptop.
There sure are many guides on the Net about how to set all up, and what to do or not to do. Unfortunately, many of them are contradicting each other (or sometimes even themselves, haha!).
All I needed to set up was the ICS itself, no disk/file/printer sharing. Thus, most of stuff that follows won’t be useful for anyone who needs also any other kind of sharing, except of the connection to the internet. To be precise, switching off all other kinds of sharing helped me to achieve much higher stability of service.
