From everything I have read about this topic, it is possible to do on a linux machine, but not with a windows machine. this could be because of something with ADB on windows, or the USB drivers for windows.

Here is the info (note that this reference was done with a Nexus One):

  • Requirements:
    • Android 2.2 (or an older version with a root tethering app)
    • ADB from Android SDK, or a rooted Android 2.2 with terminal in root mode

STEP 1:
Device: Connect USB cable and activate USB Tethering. You should see on linux new network interface.

STEP 2:
On Linux Computer, setup a bridge:

  • usb0 is the new network intreface
  • eth0 is the main interface connected to internet (or a gateway)

    $ sudo ifconfig eth0 0.0.0.0
    $ sudo ifconfig usb0 0.0.0.0
    $ sudo brctl addbr br0
    $ sudo brctl addif br0 eth0
    $ sudo brctl addif br0 usb0
    $ sudo ifconfig br0 up
    $ sudo dhclient br0

See Network Connection Bridge Help to setup bridges

STEP 3:
Setup usb0 interface of your phone. You have to options:

  1. From your computer, execute:

    ./adb shell netcfg usb0 dhcp

  2. Or in a root terminal on your phone, type:

    su netcfg usb0 dhcp

You should now be able to connect to Internet on your phone using your computer's Internet connection.

Try to do a ping www.google.com to be sure

STEP 4:

To shut down the reverse-tethering, first unbridge interfaces on your computer:

$ sudo ifconfig eth0 down
$ sudo ifconfig usb0 down
$ sudo ifconfig br0 down
$ sudo brctl delbr br0
$ sudo ifconfig eth0 up
$ sudo dhclient eth0

Then on your phone, uncheck the USB Tethering option

i am using a DSL connection and upon running sudo ifconfig eth01 0.0.0.0, i got this SIOCSIFADDR: No such device,so i renamed the connection to eth0 ,then it worked fine –  ProgramME May 28 '11 at 1:48
    
i didn't switch off usb tethering –  ProgramME May 28 '11 at 1:51

The best and simplest idea in the long run would be to get a wireless broadband router that also supports ethernet (wired networking). Your pc can still use cables and your android phone just connects to it using wi-fi.

Without a wi-fi router you still have a few more options that work with Windows, as long as your pc has wi-fi (which you can get using a simple USB network card that costs less than 20 USD). In this case you have a few options (in order of recommendation):

  1. Use software to turn your pc into a wifi router that shares it's internet connection. Instructions are available here.
  2. Setup an ad-hoc network with Windows and then root your android phone to enable it to see ad-hoc networks using the instructions found here.
  3. Use Wi-fi Direct which is a new protocol that'll work with Android 4.0 and Windows 8 (not very helpful, I know).
