The only problem I have with "Internet Sharing" is that Windows Vista won't let me use it with "Internet Connection Sharing".
I wish it would. Does "Internet Connection Sharing" work for anyone using "Internet Sharing" on their Apache?
I liked sharing my EVDO connection throughout my WiFi system to get my laptop, Playstation 3, and Wii online. It actually works fine for online gaming via PS3 and Wii Shop for Wii. It's better than the 31.2kbps connection I'd have to use otherwise.
WModem doesn't ever work for me (via USB), even right after a soft reset.
