Re: How to get tether to work (solved)

(1/5) > >>

ooseven:
I have a Blu Dash 4.5 Android version 4.2.1 Kernel version 3.4.5. It has the tether plus bluetooth WI-FI hotspot all
there. Linux lite see it but does not get ff to work. What do I need to do to get it to work?

Hello!

Your phone COULD be 'timing out' the cellular data connection to save power. On MY phone, I have to use an app called Battery Booster to set the phone to 'Basic Saving Mode'. This keeps the data connection alive.

I have a similar phone (BLU Advance 4.0), and I tether (and hotspot!) on it using LL from time to time without issues - even on Net10.

NB: On Net10/StraightTalk phones bought from retail outlets, these features are disabled in the ROM by the carrier - another reason to Bring Your Own Phone to Net10, StraightTalk, etc.

On the phone, I have USB debugging enabled, disable WiFi, go to System Settings > More (under Data Usage) > Tethering & Portable Hotspot, and check 'USB tethering'. In LL on MY PCs, this shows up as 'Wired Connection 1'.

Since Linux and Android use the same default TTL (time-to-live) for IP packets (64ms), it shouldn't be giving you a problem. In this case, cellular carriers can't tell whether you're on the PC or on the phone, since the IP packets share the same TTL.

Another little tidbit: if you change your default TTL in Windows from 128ms to 64ms, you can ALSO tether to a Windows PC with an Android phone. Google it to see exactly how, but it involves adding a registry entry to specify the DefaultTTL to be 64ms on the Windows box. Again, they think you're on the phone.

I wouldn't be caught dead owning one, but I imagine this would also work on a FruitPhone (iPhone) but setting the default TTL to that of a FruitPhone, but not sure how to do that in Linux...

It shows up like you said but can't get the firefox to run off it. As you can see above it sees it.

Hello!

Under your usb0 (your phone), I see it returning an IPv6 address for the phone, but no IPv4 address. (I don't use IPv6 here at all, but I see an IPv4 address for your LAN connection.)

Here's MY usb0, which, when the tethering cable is connected, spins the network indicator in a circle as soon as I select 'USB tethering' on the phone, then connects as 'Wired connection 2', and shows up that way on the menu that comes up when the network icon is left-clicked:

usb0      Link encap:Ethernet  HWaddr ae:c5:84:f8:38:5d 
          inet addr:192.168.42.64  Bcast:192.168.42.255  Mask:255.255.255.0
          inet6 addr: fe80::acc5:84ff:fef8:385d/64 Scope:Link
          UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
          RX packets:18 errors:0 dropped:0 overruns:0 frame:0
          TX packets:55 errors:0 dropped:0 overruns:0 carrier:0
          collisions:0 txqueuelen:1000
          RX bytes:1930 (1.9 KB)  TX bytes:14003 (14.0 KB)

Right-click on the network icon on the taskbar and select 'Edit connections'. Select the connection for your phone. Is the 'Available to all users' box checked? It COULD be THAT, but I doubt it.

I use 32-bit LL on this laptop; I'll try things out with the 64-bit version. My BLU is software-rooted (Framaroot), but that shouldn't make a difference, as all this worked for me before I rooted the phone.

Unless someone else steps in with more insight than I have, I THINK this pretty much covers all the bases, as RNDIS support is built into the kernel, UIAM...
