How to Turn Your Droid X into a 3G Hotspot
You can configure the Droid X to share its cellular data network connection with as many as eight other devices. Those devices connect wirelessly with your Droid, accessing a shared 3G network just like a laptop computer or other mobile device accesses a Wi-Fi network.
Touch the Launcher button on the Home screen.
The Applications Tray opens.
From the Applications Tray, open the 3G Mobile Hotspot icon.
You may see text describing the process. If so, dismiss the text.
Touch the 3G Mobile Hotspot check box to place a green check mark.
A warning message appears, recommending that you plug your Droid X into a power source because the 3G mobile hotspot feature sucks down a lot of battery juice.
Touch the OK button to dismiss the warning.
If you've not yet set up a 3G mobile hotspot, you need to supply some information.
Input a password for your Droid X hotspot.
The password must be applied, and it must be at least eight characters long. Give this password to the people you want to share your cellular network with.
Touch the OK or Save button to save your settings and set up the hotspot.
When the 3G hotspot is active, a Mobile Hotspot Service status icon appears. You can then access the hotspot using any computer or mobile device that has Wi-Fi capabilities.
To turn off the 3G hotspot, open the 3G Mobile Hotspot app and remove the green check mark. Also, keep these points in mind:
Whether your Droid X allows for 3G data sharing depends on your cellular carrier. Some carriers may limit that ability, and others may charge extra.
You cannot activate 3G network sharing and use a Wi-Fi connection at the same time on the Droid X.
To change the hotspot settings, press the Menu soft button when using the 3G Mobile Hotspot app. (You have to stop the service first.) Choose Advanced and then choose Wifi AP Mode. You can change the device name, security, password, and channel. Touch the Save button to confirm the new settings.
