My latop is connected to a wired modem for internet. I want to access internet on my android phone.
Can i do it by connecting my Android to laptop via usb cable and then enabling tethering.
Operating System: Ubuntu 12.04
You will need do a reverse tether. As far as I know, the phone must be rooted for this to be done.
Here are instructions at XDA Developers - HOWTO: Ubuntu USB reverse tethering
Here's the closest to a "one-click" solution that I got to.
