Here is a quote from the manual that was posted earlier. For all you people who have never had a Vanilla Android device, this may come as good news to you:
Share your phone's data connection as a portable Wi-Fi hotspot
1
Go to Settings > Wireless & networks > More > Tethering & portable hotspot.
2
Check Portable Wi-Fi hotspot.
After a moment, the phone starts broadcasting its Wi-Fi network name (SSID), so you can connect to it
with up to 8 computers or other devices.
To stop sharing your data connection, uncheck
Portable Wi-Fi hotspot.
Rename or secure your portable hotspot
You can change the name of your phone's Wi-Fi network name (SSID) and secure its Wi-Fi network
when it's acting as a portable hotspot.
1
Go to Settings > Wireless & networks > More > Tethering & portable hotspot.
2
Make sure Portable Wi-Fi hotspot is checked.
3
Touch Configure Wi-Fi hotspot.
The Configure Wi-Fi hotspot dialog opens.
4
Set your name and security options as follows:
Change the Network SSID (name) that other computers see when scanning for Wi-Fi networks.
Choose a security option. Choosing WPA2 PSK adds a password field to the Configure Wi-Fi
hotspot dialog. If you enter a password, you will need to re-enter that password when you connect to
the hotspot with a computer or other device. To remove security from your Wi-Fi network, choose
Open
.
5 Touch Save.
