HP TouchPad is perhaps the hottest tablet available that recently got some Android love. Although complete Android builds are available for TouchPad, but most of them are filled with bugs and other issues. Some folks, however, have decided to remain on WebOS unless a stable Android build surfaces with lesser bugs. HP TouchPad doesn’t connect directly to Ad-Hoc Wi-fi connections. Here is the step by step guide to enable Ad-Hoc Wi-Fi connectivity of your TouchPad with Wi-Fi hotspots e.g. your Android phone.
1. The first step is to enable Dev Mode on your HP TouchPad along with installing Preware with all feeds. You can consult the link provided in requirements section to do this.
2. Once done, disconnect any current Wi-Fi connections.
3. Now delete all Wi-Fi Profiles on your TouchPad by going to Settings > Wi-Fi > Stored Profiles and swiping stored profiles to right or left and select delete. You must keep your Wi-Fi on during this process.
4. Now start your phone’s / device’s Wi-Fi Hotspot from settings with no password or encryption.
5. Now launch Preware on your TouchPad and install Xecutah which will auto-start xterm and xserver.
6. After the installation is complete, launch Xecutah and and start Xserver.
7. Now go back to Xecutah and start xterm.
8. After this go back to xserver window where you should be able to see a green command prompt.
9. Now input the following values in command prompt:
iwconfig eth0 mode ad-hoc essid [Your Hotspot’s Name]
echo nameserver 220.127.116.11 >> /etc/resolv.conf
echo nameserver 18.104.22.168 >> /etc/resolv.conf
10. Once done, launch browser and check if you are connected to the internet.
And there you go! You now have your HP Touchpad tethered to your phone via Wi-Fi. Please note that this method isn’t very safe as you will be leaving your hotspot unencrypted without a password. In case you are stuck or need more information, then head to the XDA thread posted here.
