Enabling WiFi wireless tethering in Garmin-Asus A10 to share 3G Internet with Samsung Galaxy Tab

I have just mentioned that Garmin-Asus A10 smartphone is a very good companion with Samsung Galaxy Tab. One of the crucial function for this companionship is wireless tethering, which is definitely possible but also not so straightforward.

This is because Garmin-Asus A10 is running on Android 2.1 (Éclair) which doesn't come with tethering feature, and Samsung Galaxy Tab is not able to connect to Adhoc WiFi hotspot (the portable WiFi hotspot running in Android smartphone or iPhone) without some tweaking.

You will need to root both the A10 and Galaxy Tab in order to achieve this. Rooting can be done using DooMLoRD's Easy Rooting Toolkit v4.0.

Once successfully rooted, you can proceed to install Barnacle WiFi Tether from Android Market to enable tethering function in Garmin-Asus A10.

You also need to replace the stock /system/bin/wpa_supplicant file in Galaxy Tab to a patched one to enable it to connect to any Adhoc WiFi hotspot. Here is the detail instruction and here is the wpa_supplicant file suitable for Samsung Galaxy Tab running on Gingerbread.

Now, tethering is ready. You only have to do the above for one time, and can enjoy the tethering function for unlimited times.

To tether the 3G Internet of Garmin-Asus A10 to Samsung Galaxy Tab, run the Barnacle WiFi Tether app in A10 and start the tethering. Then, enable WiFi connection in Galaxy Tab, and you will soon see them associated.

If you have other Android smartphone running on 2.2 (Froyo) and above or Apple iPhone 3Gs and above, you can also tether to Galaxy Tab after replacing the wpa_supplicant file in the Galaxy Tab with the patched one as mentioned above.
