How to get internet on your phone via USB

You may also call this reversed USB tether.
This might come in handy if you're near a computer (Win XP/Win7) and there's no Wifi to connect to etc..
So after some research and trying I've found some information on how to do this.
Requirements:
* Android 2.2 (or an older version with a root tethering app)
* ADB from Android SDK, or a rooted Android 2.2 with terminal in root mode
STEP 1:
Install USB drivers from Android SDK.
STEP 2:
Connect USB cable and activate USB Tethering.
You should see a new network interface. (On XP you might need to install the RNDIS driver manually, see below)
If you're also missing RNDIS driver on Win7, look here.
Win XP manual driver install Android USB Ethernet/RNDIS: (You can skip this if you're on Win 7)
1. Download the following configuration file inside the *.zip attached to this post (tetherxp.inf) to your Windows XP computer.
2. Use the USB cable that came with your phone to connect your phone to your computer.
3. On the Android phone, press Home > Menu > Settings to open the Settings application.
4. Press Wireless & networks > Tethering & portable hotspot.
5. Check USB tethering.
6. When Windows XP’s New Hardware Wizard opens, select No, not at this time and click Next.
7. Select Install from a list or specific location and click Next.
8. Click Browse to browse to the directory where you installed the configuration file you downloaded in Step 1 and click Next. Windows XP uses the configuration file to configure itself to support USB tethering with the Android phone. (This might take a while)
9. When Windows XP finishes installing the software for Android USB Ethernet/RNDIS, click Finish.
STEP 3:
Bridge the 2 network interfaces.
STEP 4:
Setup usb0 interface of your phone. You have to options:
1. From your computer, execute:
./adb shell netcfg usb0 dhcp
2. Or in a root terminal on your phone, type:
su
netcfg usb0 dhcp
You should now be able to connect to Internet on your phone using your computer's Internet connection.
Try to do a ping www.google.com to be sure.
STEP 5:
To shut down the reverse-tethering, first unbridge interfaces on your computer:
sudo ifconfig eth0 down
sudo ifconfig usb0 down
sudo ifconfig br0 down
sudo brctl delbr br0
sudo ifconfig eth0 up
sudo dhclient eth0
Then on your phone, uncheck the USB Tethering option.

It is working now. After setting up ICS type in console emulator on your phone:
ifconfig usb1 192.168.2.2 netmask 255.255.255.0 up
route add default gw 192.168.2.1 dev usb0
iptables -F
iptables -F -t nat
setprop net.dns1 8.8.8.8
setprop "net.gprs.http-proxy" ""

Hope this helps some one who wants this to the right direction.
And maybe we're able to create an app to do this all automated.
Known issues but does not apply to all users:
1. Internet in browser application does not work.
2. Can't ping domain name.
For a little more info check out the sources, this includes the Linux version too.

Nice info
Going to post a link on the hero forum where someone was wanting to do this. I wonder if this will work on a froyo hero too...

it would be cool if one of the devs could write a small app to switch this on n off great find tho shoemeistah

Thank you for the guide, It worked fine. There are several things not working though:
- can't download apps from market, they stuck on "downloading"
- my google account don't sync
- other apps don't update themselves. For example my twitter app won't show any new tweets until I open it and manually press "refresh"

I searched for this long time ago, even created a thread about it awhile back, didnt have luck like you did though
I gave up on it eventually, it would be nice to make an app out of it.
mind asking how did you confirm the net to be working on browser? by pinging google.com?
since i saw the last line you put "Internet in browser application does not work."

You can do that in the terminal

[U][B] Internet connection on your Android phone via your PC [/B][/U]
I think I found the best solution. Check it out connectify.me
I wanted to use my PC wired internet & I was astonished that this wasn't available in my HTC Desire & 1st Android device!. I looked over the net, I found many options but most asked for a rooted device! I didn't want to root my brand new Desire.
Connectify is an easy to use software router for Windows 7 computers. After downloading and installing the lightweight application, Connectify utilizes your computers' built in Wi-Fi card to wirelessly share any available Internet connection: a cable modem, a cellular card, or even another Wi-Fi network. Other Wi-Fi enabled devices including laptops, smart phones, music players, and gaming systems can see and join your Connectify hotspot just like any other Wi-Fi access point and are kept safe and secure by password-protected WPA2 Encryption.
I tried it & it's working perfectly for me .. It's a free app.
-----------
Phone: HTC Desire (SIM Free)
Type: Desire
Build: HTC Desire 2.2, 2.10 (kernel: htc 2.6.32.15)
Baseband: 5.09.05.30
Network: UMTS auto (EGY)

By me it didn't work. Using OpenDesire with Froyo 2.2
So I made it work, by edititng the .inf file.
Here the file for USB\VID_0BB4&PID_0C02.
For all which still have a problem(USB TETHERING ON DEVICE MUST BE ACTIVE, ALSO THE IDs DIFFERS BETWEEN CONNECTED WITH ADB OR NOT), go into the device manager -> open the device -> goto tab details -> choose device id
look at it, you see somewhere vid_XXXX and further pid_XXXX
open my file -> goto line 31 -> change vid_YYYY and pid_YYYY with what you see in your device dialog. the same you do on line 35. be careful with 0 or o.
Regards
Ralph

I am also using connectify, easy to install, set it up, connect with Desire, anything works fine.

Thanks GhostOfTheNet.

I appreciate the recommendations for other solutions.
But as you can see this thread is for a internet solution at places where is no Wifi available.
So please keep it on topic, thanks!

browser & webviews
Any idea why browser won't work?
I'm interested in testing against internal sites (of course no WAP here.. cuz they be scared i guess).. both Browser and embedded webviews.

connectify great program.works fine

its a default feature in hd roms but that doesnt work in all programs

Connectify doesn't work correctly with my Galaxy 5. It keeps connected for a short time then disconnects and then, connects again, connect, disconnect...
Does anyone know how to fix it?

Thanks Man

plz make a video tutroial of this
its difficult to under stand

does it actualy work?? anyone tried this and actualy worked??? just a simple yes or no.
thanks

small proble plz solve it
hi
I have a small problem in it when my device is not in usb tethering mode
i can see it in my adb devices
as soon as is start usbtethering it say no device found
plz help me

thanks a lot !!!

realy nice guide! Thanks!

[Q] Use PC's Internet via USB at Defy (opposite of thethering)

At home or in office, Defy is connected via USB to PC (to load). Is it possible to use the PC internet connection also for the Defy - maybe with the Motorola Software? In this case Defy gets an IP, so there must be some connection.
I miss this feature from WinMob (via ActiveSync) which can exactly do this.

The developer of "Moto Tethering USB" plans to add this feature. I don't know any other solutions, so you'll need to wait for that. Unless someone else knows something. I'd be especially happy for a solution that work on Linux (Moto Tethering USB doesn't).

Good to know. I have encouraged him in his thread.

Nice Question.....I'll wait for the Answer...

The procedure for Reverse USB Tethering with Android 2.2 given on this page might help... blog.mycila.com/2010/06/reverse-usb-tethering-with-android-22.html

it's pleasure to hear the new plan
there's already a app that can auto set the htc phone sharing the PC' net connection via usb
and defy is also badly in need of one

Is is easy on LINUX. You must use adb from android sdk tools.

There is one problem. Downloader didn't works. It can't detect, that Android is online. It thinks that connection is closed. But browsing on market, browser, opera, all applications, that did'nt detect type of connection, work normal.
Have anybody solution?

Are there any news to reverse tethering? Best under Windows?

this will be simply awesome.........
as i dont have wifi at my home i am looking for this....

did anybody find something on this...

U can try this one..
If u hav wifi facility in ur laptop or desktop, u can use connectify software to share ur internet connection.

shall be waiting on this .... specially for windows

For windows you will find this thread helpfull

informative

can't we.
isn't there a way to treat defy as a pc give it static ip on the network or using ics and add a route to using the pc internet? when i connect my defy it get an ip on my home router.
is there any ideas.

Tethering issue

I'm trying to tether my Evo with my HP netbook that's currently running Blackbuntu which is a pen test distro based on Ubuntu 10.10 and using Wicd as my network manager. With the default network manager usb tethering worked "out of the box" but unfortunately I was unable to use WiFi with it which forced me to use Wicd. In order for Wicd to function properly I had to fully remove the original network manager. Now I can't figure out how to configure Wicd to work with tethering. Somewhere I read all I have to do is change the wired interface in Wicd from eth0 to usb0, or something along those lines, so I tried ifconfig to verify and nothing showed up other than eth0, lo, and wlan0 - the 3 that always show up. I can't seem to find the tethering tutorial I read before to double-check it. Any help/ideas would be great.
EDIT: I figured it out on my own. I just had a brain fart for a bit. For anyone wondering how to do it, here's how:
On your Evo open a terminal and do the following.
su
busybox ifconfig
Write down the IP address given.
Connect your phone to your Linux box and start USB Tethering.
On the Linux box open a terminal and type:
sudo ifconfig usb0 up
Open Wicd, click preferences, and change the wired interface to usb0. You may have to set DNS1 to the IP you copied earlier.

[SOLVED] OpenVPN Full Tunnel

Short Version:
Got an OpenVPN server on my NAS. GN connects & works fine; remote resources are reachable. I now want to know how I can route all traffic through the tunnel. (Is this possible?)
Long Version:
For those times when I'm traveling (domestically and internationally) and/or using a questionable Internet connection, I'd like to secure the connection.
I've got a [stock] rooted GN running Jelly Bean with BusyBox installed. My NAS has two built-in VPN solutions one of which being OpenVPN so I got that setup which created an .ovpn file containing the following configuration:
Code:
dev tun
tls-client
remote YOUR_SERVER_IP 1194
# The "float" tells OpenVPN to accept authenticated packets from any address,
# not only the address which was specified in the --remote option.
# This is useful when you are connecting to a peer which holds a dynamic address
# such as a dial-in user or DHCP client.
# (Please refer to the manual of OpenVPN for more information.)
#float
# If redirect-gateway is enabled, the client will redirect it's
# default network gateway through the VPN.
# It means the VPN connection will firstly connect to the VPN Server
# and then to the internet.
# (Please refer to the manual of OpenVPN for more information.)
#redirect-gateway
# dhcp-option DNS: To set primary domain name server address.
# Repeat this option to set secondary DNS server addresses.
#dhcp-option DNS DNS_IP_ADDRESS
pull
proto udp
script-security 2
ca ca.crt
comp-lzo
reneg-sec 0
auth-user-pass
After installing OpenVPN Installer & OpenVPN Settings, I had to manually symlink busybox, ifconfig, and route from /system/bin to /system/xbin in order for OpenVPN to run properly.
Code:
#Note: In an attempt to be thorough, and for any Googlers or forum searchers (+1)...
#First I had to mount /system as read/write via:
mount -o -rw,remount /system
#Then create the symlinks via:
ln -s /system/bin/busybox /system/xbin/busybox
ln -s /system/bin/ifconfig /system/xbin/ifconfig
ln -s /system/bin/route /system/xbin/route
#Then remount /system as read-only via:
mount -o ro,remount /system
Once all of the above was setup, I initiated the connection, successfully authenticated, and was able to reach remote resources without issue.
What I would like to do at this point is get it setup so that I can have a second profile that routes all traffic through the VPN. I assume its a client-side configuration change but I really don't know at this juncture.
Many thanks!

Doesn't CyanogenMod ROM have native OpenVPN support? I think the OpenVPN client on CM has an option to route all traffic through the VPN. I think for what you want to do you should need a custom ROM or kernel that supports iptables.
iptables is a system file that allows the system to redirect network traffic usually for apps like tethering, firewalls, and proxies.

Thanks for taking the time to reply KemikalElite.
I've got BusyBox 1.20.2 installed and I do have an iptables binary (v1.4.11.1). With solutions like Hotspot Shield VPN that don't require root yet supports encryption for all traffic, I figured root + OpenVPN + BusyBox + iptables would be sufficient.
My initial assumption was that I would need to make some changes to my OpenVPN configuration to encrypt & route all traffic through the tunnel. But maybe I've been thinking about this all wrong and its less about OpenVPN and more about running a custom script once connected to route everything through the tunnel; and vice versa when I disconnect to restore the original configuration.
Perhaps I should be scouring OpenVPN forums?

You have the tun module as well right?
code.google.com/p/android-openvpn-settings/issues/list
Check through some of those issues. Something did say that the DNS servers may need to be manually set.
OpenVPN is so complex because of the config options. I find it easier to use native PPTP connections since there's no config only authentication and it routes all traffic automatically.

You need to enter "redirect-gateway" into your ovpn config file.... Just remove the # in the your config

Thanks for the reply ZiCoN!
I should have mentioned this sooner - terribly sorry for omitting this.
Once I got the VPN connected, I did the old 'what is my ip' to verify the route. It was still using the provider's network, but I could reach my NAS and other remote devices in the 192.168.x.x range - so the VPN itself was working. After reading the mini explanation in the config file I enabled 'redirect-gateway' and after reconnecting I could no longer access the Internet. I checked the OpenVPN Manual I added 'def1' after the 'redirect-gateway' statement, reconnected but still no go: I can no longer access the Internet. Remote resources are still accessible in both scenarios.

I somehow missed this when drafting my last reply. I think you're right about it being a DNS problem. I made a change to the config file (adding a few lines for 'dhcp-option DNS x.x.x.x') and within OpenVPN used the 'Fix DNS' button.
Thanks all for your time, thoughts, opinions and instructions!

You probably need to allow traffic to route back along the vpn film the internet. On your gateway, route vpn addresses to the VPN server and make sure forwarding is enabled on the vpn server.

[Q] Help ? Xperia ARC+DarkKernel+LX : Wifi almost working, only sees the gateway

Hi,
This is my first post, on this great forum, so I'm posting as a "noob"...
So my problem :
- I installed the LegacyXperia 20130908 CM10.1 release. It was working almost OK
- But because of the high wifi drain, I gave the lated DarkKernel a try (http://forum.xda-developers.com/showthread.php?t=2451839)
It seems to perform very good BUT I just noticed something really weird : I have access to the internet through my wifi LAN, I can ping my gateway BUT nothing else works on the local LAN :
ping fails :
[email protected]:/ $ ping -c 1 192.168.1.13
PING 192.168.1.13 (192.168.1.13) 56(84) bytes of data.
From 192.168.1.10 icmp_seq=1 Destination Host Unreachable
The arp table seems incomplete :
1|[email protected]:/ $ arp -a
d810.home (192.168.1.13) at <incomplete> on wlan0
livebox.home (192.168.1.1) at 00:1f:95:26:25:4d [ether] on wlan0
The routes seem ok, the ip neighbours are not :
[email protected]:/ $ ip route show
default via 192.168.1.1 dev wlan0
192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.10
192.168.1.1 dev wlan0 scope link
[email protected]:/ $ ip neighbor show
192.168.1.13 dev wlan0 FAILED
192.168.1.1 dev wlan0 lladdr 00:1f:95:26:25:4d STALE
AH, on more weird thing, the kernel arp table has lots of zeroes for the unreachable devices MAC adresses (yes, I have 192.168.1.13 and 1.15 are up and running) :
[email protected]:/ $ cat /proc/net/arp
IP address HW type Flags HW address Mask Device
192.168.1.1 0x1 0x2 00:1f:95:26:25:4d * wlan0
192.168.1.15 0x1 0x0 00:00:00:00:00:00 * wlan0
And I can't seem to be able to communicate with the local LAN only with the android phone...
I have static IPs in my DSL router, I can't set the arp tables manually.
I *think* this was all working with the default ROM kernel, but before I attempt to revert back to that kernel to check (I backed up the modules, but yet another noob thing, I'm not sure putting back the tar into /lib/modules will be enough...) :
==> this is my noob question : anybody knows how I can report that to the dev, and how I can get help ?
Since it's my first post (only 9 remaining now !), I can't post in dev section...
Thanks && regards

Did you flash the DarkModules?

Hi,
Yes i did flash them in cwm...

Hi,
Thanks for the reminder.
But actually, by dev, i meant the kernel dev : the issue i see is not a force close or things like that,
and it appeared after i flashed this new kernel which seems better for the battery.
I think this is a kernel/wifi modules issue, not a rom one.
Or a noob error, but then i hope some of you can help me understand my error
As i said, wifi is somehow working since i'm replying just now using it...
It's just that apart from the dhcp/gateway, my device seems unable to learn any mac address with this kernel.
I haven't tried a tcpdump for now, and i wanted to test ipv6 but my 'great' dsl/wifi box does not support v6 - yes, that still exists...

He is also developing the kernel together with his team, which is given within the .zip file.

Ahh... txs.
OK, now I don't understand anymore anything...
I did :
- remount rw /system/
- cleanup and then restore the /system/lib/modules backup I had done - using tar
- reflash the ROM kernel (200130908)
And... still no ping on the wLAN, but I can ping google and the GW. ??
The arp table still shows me incomplete records.
Still I'm 100% sure I could connect before : I did use connectbot to ssh onto my computer and setup new ssh keys.
I don't know what else I can try exept reboot the dsl box (which is the wifi router)... or delete the recorded stuff in that dsl box and that reference my arc s.
Or reflash all, but I always manage loosing stuff when I reflash (which I avoïd doing then), even with titanium backup
That's all really weird...
Side question : is there *always* a captcha verification on every post ?
Cheers

Which DNS server are you using? Did you change anything else by WiFi?
The captcha is only for limited amount of posts, then it will disappear.

I did not change any dns setting, but i saw local names in the terminal, so i must be using my dhcp/box dns.
You remind me i unchecked the wifi optomizations with the new kernel: i read this was causing arp issues on nexus devices...
Lets try to re-enable that... appart from this, i changed nothing after i flashed this kernel.
Except I tried 1.8ghz (it worked well), but this disappeared sincei restored the official rom krtnel
Thats really all i changed since i tried the new kernel yesterday evening

Can you believe this...
- Restoring the wifi optimisations did not help
- rebooting the DSL box helped. For 5 minutes.
I was able to ping a computer on the network, but not to go to the dsl box webserver. and I lost internet.
- subsequent dsl box reboots did not solve anything : no internet, no webserver, no connexion even on the wired PCs , powerd them on or off, nothing.
- *unplugging* everything + dsl box reboot => did restore internet+wifi on the arc
- replugging the PCs did not break
- and I can now see/ping the LAN with the arc s
Only remains, now, the dlink switch I have downtstairs that is the only stuff that remained plugged all time (theres a device on it, but it's off)..... It must have switched to a "netkill" state somehow. Funny, isn't it ?
let's now start wireshark, reinstall the new kernel, and see if there is any difference... and lastly reboot/replug the dlink switch
the come back for the (arp) ping of death ?
Regards

Last experiments:
- fired wireshark, to capture any network suspicious paquets
- reflashed the new kernel+modules
- retried ping / local LAN
Still working.
I rebooted my last network device (dlink switch), repluggued it : everything is still working.
conclusion : I don't understand :laugh:
Cheers
