With the fall in mobile internet prices, it is becoming more common for people to switch to a broadband connection over a shared mobile connection with all the devices in the house. The most common way to do this is by acquiring a chip with active data plan and inserting the same into a 3G router, which will distribute the internet via cable or even wi-fi throughout the house.
But if you already have an Android phone and do not need your shared connection all the time, an interesting way to have internet on other devices is to share the device’s data plan. Android devices from version 2.2 has the option of making the so-called “tethering” which is nothing more than sharing the 3G internet through Wi-Fi. In this case the phone serves as a wireless router that creates a wireless network and several devices such as a notebook or even other mobile handsets can connect to the internet through this network.
Another option I use most often is the so-called “USB Link” that does the same thing but instead of creating a 3G network, the phone becomes a kind of 3G modem, which is detected and installed on the computer when it is turned on. In Windows 7 and using Android 2.3.7 CyanogenMod 7 in Motorola Milestone the modem was detected and installed automatically.
The speed of the PC connection was exactly the same as the 3G connection on the phone. I did some speed tests and did not notice any losses. The main advantage I saw in using the USB link instead of tethering from wi-fi is that the phone charges the battery while it is plugged into the USB and you do not risk forgetting to connect it to the charger before.
Now that you already know how to share and internet phone with your computer, just be careful not to burst the data franchise if you have one!
