How to use WiFi tether on your Android smartphone or tablet for free [Guide]

i_love_tetheringSharing your smartphone or tablet’s internet connection with another device or computer is known as tethering. Tethering is a very popular use of many smartphones (and some tablets), but many cell phone carriers in the United States also charge as much as $15 per month for the added feature regardless of the amount of data on a subscribers plan. This guide will show you how to enable tethering on your Android smartphone or tablet without getting charged by your carrier.


This app requires a rooted Android smartphone or tablet on Jelly Bean or Ice Cream Sandwich. If you don’t have a rooted device, either root your device or check out FoxFi tethering without root access app. If you have a rooted device but don’t have Jelly Bean or Ice Cream Sandwich, check out dotTech’s review on best free tethering apps to learn how to tether with your device.


  • Download the Treve Mod WiFi Tether app from here on your phone or tablet and install it using your favorite file manager. You will need to sideload it onto your device, meaning you will need to enable Unknown Sources from device settings.
  • Launch the app then tap on the menu and select the settings option.
  • After that, choose “change device-profile”. “Generic ICS/JB (wlan0)” is the option you need here.
  • Then select “Send Netd Max Client cmd” from the menu that pops up.
  • The next option you should choose is “WiFi-driver reload” or “WiFi-driver reload 2“.
    • I recommend choosing the first option, and if you do not get any errors going forward, you will be fine, if you do receive errors when trying to enable the tether, then you should go back and select the second option.
    • There are so many different Android phones that it is almost impossible to make a full chart for which option to select for each phone.
  • After choosing your WiFi driver, you will need to scroll down check “MSS clamping” and “Routing fix”.
  • You should then be able to turn on tethering by choosing the WiFi icon, and then hit “Menu -> Show log“.
  • If there are no errors, you are good to go. If there are, you should then choose the other WiFi driver. After than, you will only need to hit the WiFi icon in the app in the future.
  • Done!

Happy tethering!

    >In other words HOW does the desktop in my office transmit the wifi signal for the laptop in the next room to pick up and connect?< I'm not sure (never done it) but to the best of my understanding the desktop pc needs to have a WiFi device (internal WiFi card? maybe even an external WiFi device?) which is used as a relay for the laptop. This works because to work WiFi devices need to send and receive, but the range will be probably be Laptop's WiFi device connects to the Desktop's WiFi device and the Desktop PC allows access to the internet through it's connection.check to see if your Desktop PC has WiFi ( If it does you can try turning it into a WiFi hotspot for your Laptop.

    Good Luck :-)

    Thank you so much. The community at this site is just the best!

  • A couple of years ago I would recommend the apps PDFnet or EasyTether, neither of which required root access, to provide the connection. This was before very many providers charged for tethering though, and I don’t know if they would help there.

    [@Grantwhy] Please help me wrap my head (pin head that it is) around this method of creating a hotspot with my desktop.

    Could I use a desktop PC connected to the internet by JUNO or a similar dialup into a virtual router (granted slow connection) and enjoy wireless use of my wifi laptop in the next room? Does it require an antenna like a router does? In other words HOW does the desktop in my office transmit the wifi signal for the laptop in the next room to pick up and connect? Stubbie, Komando coathanger, etc?

    I’m not sure about doing it through a USB connection, but you can turn a laptop (or desktop) computer into a WiFi hotspot.

    here is one bit of software that will do it, reviewed on dotTech :

    For ZAC —

    I see, so your android cell phone running a rooted system and this app can provide a “hotspot” for another person operating a Windows Laptop by using the cell phone as a “central” Web connection.

    But, I have a found an Android app that does NOT require rooting yet provides that valuable HotSpot like it did for me at the beach last week when the beach house did not provide us with a Wifi connection Hotspot itself.

    So Rooted vs. Not Rooted is the question.

    I am scared to root my Samsung Galaxy S3 while under my Verizon’s contract. So I found an app that does the “dirty deed” for making a “hotspot” for free that eliminates the need for rooting my phone.

    Worked fine for Googling recipes and restaurants’ menus at the beach and my Gmail email, 60-90 minutes a day or so for 5 days. I asked Verizon staff to check my bill when I got back and no data was spent much at all. I was secretly amazed but then, I didn’t use it for streaming Movies and watching YouTubes and such.

    ZAC, have I stated this correctly? I bow to your expertise in this matter.

    Silly me, but how about the reverse? Can my Androids get online through a USB connection on my laptop?

    Or when there’s not WiFi somewhere you want to use your laptop or WiFi only tablet.

    Tethering is useful for granddads when grandkids come around with their iPads and Nooks wanting to get on quickly.
