I have a Wi-Fi issue too. In Vista i have easily created a ad-hoc network connection so who ever i gave the password could surf the web. Well, it seems that in Win7 RC it is not posible. I've tried several methods , i've read the forums but i couldn't find any info about "how to turn your laptop in a Hot Spot". Anyone has any idea?

Try this:After connecting to your wireless network, go to Start>Control Panel>Network and Sharing. Click on your connections and then properties when the connection dialog box opens. When the properties dialog box opens you'll see the sharing tab at the top. Click on that. Then click on/check "Allow other users ..." Uncheck the box for others to control the connection.There is a link for further configuration help there also if that doesn't help.The other issue that you may run into will be the Homegroup settings. Ping back on this thread if that causes you headaches. Good Luck.
