samsung galaxy s 3 - When tethering, is there a way to turn off the phone's own data usage?

  • dunc

    Just a quick question, really.

    When I'm tethering (via USB, or wireless, or whatever) my phone's apps (and there are a significant number of my apps which do this) are constantly using the phone's mobile data connection to push notifications.

    My phone's mobile connection is poor at the best of times (Samsung Galaxy S3 on o2 in the North East of England), such as now, where it's constantly flicking between G, E, H, H+ and 3G.

    As such, I'd like to effectively "disable" my phone for every purpose other than providing an internet connection my laptop via USB or wireless.

    Is that possible?

    Try Android Firewall from the Play Store. You could create a "White list" that starts off with denying all network activity for all apps, to which you'd then allow just your tethering to go through.

    Then, when you want everything to go through again, just disable the firewall...Or better yet create another white list that you can switch to.

    Take a look at this article. I think what you're looking for is "Restrict Background Data." Keep the tethering app in the foreground and every other app will be starved of connectivity.

    Restrict Background Data: This option prevents all apps and services from using data in the background. Apps that depend on background data won’t work how you’d expect them to – for example, Gmail won’t automatically download new messages in the background if you enable this option.

    tethering - How can I tether my phone's network to my pc?
  • lamwaiman1988

    I tried the "Android wifi tether" app and "Clockworkmod", both are not working. I am looking for free solution.

    I am using LG Optimus Black and is 2.3 root.

    I tried the "Android wifi tether". I can enable the "tether" on my phone and its icon change color too but I cannot find anywhere I can connect to this claimed wifi hotspot network in my Windows 7. I opened the Network and Sharing Center and cannot find any possible wifi. Strange enough, my pc doesn't seems to found any wifi.

    I tried the "Clockworkmod" app. It works sometimes but most of the time failed. Some days I can connect my phone's network with it and most other days can't. I tried turn off my anti-virus and firewall too. Here is a example log:

    C:\Program Files\ClockworkMod\Tether
    "Local Area Connection 2"
    Checking arguments...
    Setting IP Address, mask, and gateway.
    netsh interface ip set address name="Local Area Connection 2" source=static 1
    Element not found.
    Setting DNS server.
    netsh interface ip add dns name="Local Area Connection 2" index=1
    The object is already in the list.
    netsh interface ip add dns name="Local Area Connection 2" index=2
    The object is already in the list.
    Adding Windows Firewall Exception
    netsh firewall set allowedprogram program="C:\Program Files\ClockworkMod\Tether\win32\node.exe" name=Tether
    IMPORTANT: Command executed successfully.
    However, "netsh firewall" is deprecated;
    use "netsh advfirewall firewall" instead.
    For more information on using "netsh advfirewall firewall" commands
    instead of "netsh firewall", see KB article 947709

    Starting Tether...
    C:\Program Files\ClockworkMod\Tether\node-tuntap
    opening tun device: null
