Look for Windows Firewall/Internet Connection Sharing (ICS) (double-click it) and make sure the Startup Type is "Automatic" and that it is running. It can be started right there too if it is not running now.
Thanks, I found a wireless usb adapter, plugged it in, and now the sharing settings are there. I'm trying to set up my laptop as a wireless hotspot. I followed tutorials I found online, and while my computer recognizes the new network as a computer-to-computer network, my phone cannot detect it - which is the point to all of this, im trying to use my phone as an ip camera over a wireless network I create.
All of the tutorials said it should appear as an access point as well, but it doesn't, only the computer-to-computer network.
