Internet on G1 via USB cable (Reverse Tethering)?

Would it be possible to get Internet on the device, through PC, instead of Internet on PC, through device?

Is there any way to do this its very important as I live in India, there is no 3g and edge is very slow so can't download themes, updates directly on my g1

Sure there is a way, WiFi
No you cannot give the phone internet via USB

Can you be more specific on how to do it with WiFi? And without a router
I tried using the AdHoc connection created for the Tethering (Internet from G1's 3G/EDGE to PC), but with no luck.
The laptop and phone can ping each other, I have done all the necessary steps to share my LAN and WiFi connection, remounted the /system partition as rw, edited /etc/resolv.conf (/etc is in fact on /system/etc and if not remounted as rw you cannot edit /etc/resolv.conf), added the IP of the laptop, but then I have some trouble adding default route to it. No matter what settings I try "route add ...", they change nothing...
No internet, no ping.

Did you set the gateway?

You have the SDcard that you can use to move files to the phone, I don't see any need to download directly to the sdcard, especially if you have the phone hooked up via USB anyways.
Kind of pointless no>?

So, I have tried at least.

How do you do it without Wi-Fi, over the USB cable? I can't set up a Wi-Fi node at work or the network security guys will send a SWAT team after me.

If you have access to a computer that has internet, and you have your usb cable, why don't you just download whatever theme/update to the computer, then plug in the usb cable and transfer it to your phone?

You have a PC or laptop with access to the internet. Why not just download stuff on to the PC/Laptop and move onto SD card.
If you want it to get on the market or watch youtube to test it out etc then join the laptop/PC's connection. Simple.

There is no solution for getting internet from laptop to the phone....
I wonder that with technology improving at such a fast pace, why any developer at corporations or independently hasnt thought about it yet. Any app, gadget or software providing a solution for this problem will sell like a hot cake especially in developing countries like south asia, middle east and africa.

Are you sure? There is a solution for getting internet from phone to laptop over USB, so why not from laptop to phone? This blog post claims it can be done, but I haven't ever seen it working: http://blog.mycila.com/2010/06/reverse-usb-tethering-with-android-22.html

This isn't a matter of "technology improving". Other phones already have it. Windows Mobile has had it for years.

I have know idea if this will work or not, but I have found this on a few different forum all posted by Diyism, so if it does work he deserves all the credit.
Code:
My android os is CyanogenMod 4.2.14.1,
1.Enable "Settings\Wireless controls\Internet tethering"
2.Install HTC Remote NDIS based Device driver([url]http://forum.xda-developers.com/attachment.php?attachmentid=277122&d=1265356413[/url])
3.Set the HTC adapter as: IP:192.168.2.1, Mask:255.255.255.0
4.Set the PC ethercard as shared connection
5.Run these codes in terminal:
su
ifconfig usb0 192.168.2.2 netmask 255.255.255.0
busybox route delete default
iptables -F
iptables -F -t nat
busybox route add default gw 192.168.2.1
setprop net.dns1 8.8.8.8
setprop "net.gprs.http-proxy" ""
6.Now your g1 could open browser to view any web pages on the internet, and update apps in the Market.

Those instructions are only for a Linux computer, though?

I have used the setups as Brock Samson has indicated and it works for me.

I was asking the same question one year ago and I think I've posted somewhere a similar method to Brock Samson's, so it will definitely work.
In fact it will be less hussle if you don't enable internet tethering in settings and just bring usb0 up using ifconfig. You must set a correct IP address and netmask before the port is up though. Otherwise the driver on the PC end will freak out.
Generally Android never uses /etc/resolv.conf. Only console programs originated from Linux use it. DNS server must be set through setprop and has to be set everytime network status changes (e.g. mobile data network reconnect, etc).
Some programs will also use Android API to detect network availability and will back out if neither mobile data nor Wi-Fi is connected, so make sure you don't turn both of them off.

[REQ] Reverse wired tethering

Before i start i want to let people know YES I DO HAVE A WIRELESS ROUTER!! So please do not respond telling me to just go buy a router.
REQUEST - Reverse wired tethering. I.E. Sharing PC's iNet connection with your phone via USB.
REASON - My university's wireless is locked down and does not allow mobile phones, pda's to connect up to our wireless without submitting MAC for approval. Looking to sync certain apps without using my data connection.
I dont know if anyone has played around with trying to get this working or not. I know its a small market of people who may be interested in this, but for certain places (CANADA) where data charges are WAY to expensive this could be handy for students at UNI where wireless is not an option.

get a second wifi adapter on your laptop, and share your uni wireless network connection with the second wifi adapter. Use a hidden SSID, then no one will know what is going on

This was asked a couple of times before here and I remember people saying you couldn't reverse the tethering.You could try though.

Thats a good idea xD

Hey guys,
I have been trying to find a way to do this for a long time.
The best solution i have found (actually the only solution) is Connectify. The only downside is you must have Win7.
What it does is turns your wifi adapter into a HotSpot, even if you are using wifi to get the net in the first place. Its a great tool and should be what your after.

thank you so much for this

Your best solution is the WiFi adapter. You could most likely get away with a SOCKS proxy over USB, possibly using adb, but it would be complicated, unstable, and messy.

I still don't know you just don't use your wireless router. I assume they have wired. Clone your PC's mac address and hook it up. Universities are retarded with that crap. They have the worst networks and security.
If no wired, then what podunk place is it? haha
Even if they had only wireless , you could set up a wlan client and repeat it. DDWRT, etc, ftw.

Just get backtrack for your laptop and spoof your mac to all 0 then grab connect to the network at your school the spoofed mac will allow you to browse so long as no other encyption is on the network such as WEP or WPA.
then you can try to flood all the ports on the network so no one else can connect then spoof your phones mac by conneecting to your laptop through wireless as an adhoc connection and while staying connected through adhoc load a second server through the same wireless network card and you can connect to the achools network again. and walla...

so simple, i dunno why i didnt think of that. thanks! lol

Well its quit simple once you learn your way around linux...

If you have any experience with *nix, you may want to look at Cyanogen's original usb tether shell script:
http://github.com/cyanogen/android_vendor_cyanogen/blob/master/bin/usb-tether
Basically you could use the internet connection sharing function that comes with all popular OSes and access your uni's network on your phone. You must have Cyanogen mod or another mod using his kernel. Not yet working on OSX for some reason. Tested under Windows 7.
First you'll need to figure out what IP address range your computer's DHCP server is using. This is normally fixed for each OS. For Windows 7, it's always 192.168.137.0/24.
For OSX or Linux, you can setup connection sharing (for some other connection because we don't have the USB interface yet) and ifconfig.
Second is to enable the USB connection on the phone's side. Type the following command in any console program, like Connectbot. (You must use a console program as opposed to adb because you will lose USB debugging once the USB network interface is enabled.)
Code:
su
cd /sys/devices/virtual/net/usb0
ifconfig usb0 192.168.137.200 mask 255.255.255.0
echo 1 > enable
The first line makes you the superuser. (Skip if the command prompt is #)
The second line land you in usb0's directory under sys. We'll need to type the disable command later, so it's easier if we're here.
The third line brings up the virtual usb network interface and sets its IP address.
The IP address should be in the same network (i.e. IP address range) you obtained in step 1. Say if the original is 192.168.137.1 in a /24, you can use 192.168.137.2 through 192.168.137.254
This actually enables the usb interface.
You will now see a new network adapter is recognized by your computer. Set up connection sharing to share your internet TO that adapter.
Make sure you have connection by pinging your computer from your phone.
For example:
ping 192.168.137.1
Now you'll have to change the routes so traffic go through the USB cable instead of the mobile network.(# is the command prompt, do not enter)
# busybox route
check the line starting with "default". Write down the ip address after it; call it IP1.
# getprop net.dns1
Call the IP returned IP2.
Code:
busybox route del default gw IP1
busybox route add -host IP2 rmnet0
busybox route add default gw 192.168.137.1
The first line deletes the old default route via the mobile network.
The second line adds an "exception" for your carrier's DNS server.
The third line adds the new route via USB. You should replace the address at the end with the IP address from the first step.
Your network should be working now. Test by visiting some website that is only available on campus or by traceroute.
You must make sure the mobile network is always connected though. This is because domain names are still resolved by your mobile carrier. If you ever lose your mobile connection, the routing table will be changed as well.
To disconnect:
Make sure you're still in /sys/devices/virtual/net/usb0.(Use pwd if unsure.)
Code:
netcfg usb0 down
echo 0 > enable
The usb interface will disappear on your computer.
Now switch the phone to airplane mode and back to re-enable mobile network.
The disconnect step should always restore your phone's state.

It's really sad that Android can't reverse tether. If you want to use your laptop's AdHoc connection you have to do serious hacking to the tiwlan.ini and the wpa_supplicant.conf. There is no way to connect via bluetooth ar USB.
I'm seriously considering WP7 now for my next OS of choice... A nd for everyone saying "go buy a router" - go buy a router and stick it up your .... nose.

Hi,
I have the same problem. No WiFi in my work and no WiFi in my current home (a Resident Hall). There's no possibility to buy a WiFi router, of course. I tried to hack the system to connect ad-hoc networks but it didn't work.
I have found some interesting resources:

I have a HTC Magic with the ADP-DRC83 hacked ROM with Usb tethering integrated. But usb0 interface in the mobile is configured to provide Internet connection (as gateway) to the PC, not the reverse functionality: connecting the mobile to Internet through the PC. So, all I need is to change the gateway in Android and then configure a NAT-DNS in my linux PC (easy with iptables and dnsmasq). But, I don't know how automatize the process exactly.

Wind will be launching in vancouver soon.

Silly ragin' cajun.

Ok, now it works. Here it's my procedure for a HTC Magic (Sapphire) without any APN previously configured from Telecom provider and ROM CSDIv4.
In the mobile by using Better Terminal:
Code:
su
cd /sys/devices/virtual/net/usb0
echo 1 > enable
ifconfig usb0 192.168.2.2 mask 255.255.255.0
busybox route add default gw 192.168.2.1
setprop net.dns1 8.8.8.8
In the linux computer:
Code:
sudo sysctl -w net.ipv4.ip_forward=1
sudo iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
sudo iptables -A FORWARD -i usb0 -j ACCEPT
sudo ifconfig usb0 192.168.2.1 netmask 255.255.255.0
Android Market downloads and location service don't work but I think is possible if you switch on the WiFi.
Update: Syncronization, Android Market downloads and location service don't work even the WiFi antenna is switched on. I have added the iptables commands also.

Well gosh, reverse wireless tethering is so much simpler

Mobile hostpot is to use the desire's wifi as a hotspot for connecting *other* devices to use the 2g/3g network.
This is for connecting the desire to a adhoc network like the wifi network on your laptop. Some laptop wifi cards for example can set them selves into AP mode so they are a true access point and the desire can connect to it, however most cards don't support that mode (well mine doesn't anyhow) so you need to create a ad-hoc network on your laptop that ultimately routes out to the internet via your wired network connection. This is where the desire cannot connect to that ad-hoc network without this 'hack'.
When you are roaming this is invaluable with extortionate roaming data charges so this is a way to reuse your wired connection on your laptop as a gateway for your desire. It's in effect a reverse hotspot.

Wonderful!!!!!
Finally!!!!I'm searching it from a lot of time!!!!
Now all works wonderful!!!
Thanks a lot to all!!

I noticed that the binary in the link above was for an older wpa_supplicant (0.5.11) and Desire and the new froyo's are on 0.6.10 of wpa_supplicant so i repatched and compiled.
For those with the writeable /system hack, just disable wifi, push this on your /system/bin and reenable wifi. Else push this at recovery time
Code:
adb push wpa_supplicant /system/bin/
I also changed the "(*)" prefix for adhoc networks as i didn't like the look of the wifi list so now it's changed to "(adhoc)" suffix for adhoc networks it sees.

Strange, then this must be a generic bug with ad-hoc networks (i.e. not something this patch/hack has introduced) so you will see the same results if you edit the wpa_supplicant.conf files manually correct ? It looks from this that adhoc supports only open or WEP encrypted network (in wifi tether too you can only use WEP). See the thread here:

Flash the zip provided in the thread, and google 'windows setting up adhoc network'
Ensure not to choose WPA2-AES key for the password, but a WEP password. Then select wifi networks on your phone and choose your network and put in the password you selected.
For linux it's easy too. First disable wifi scanning on your applet in the top right as you want to disable it as a client and make it as a server. So as root do this (assuming your wireless interface is called wlan0) and want to create a network on 10.0.0.x
Code:
DEV=wlan0
iptables -t nat -D POSTROUTING -o eth0 -j MASQUERADE
iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE
echo 1 >/proc/sys/net/ipv4/ip_forward
ifconfig $DEV down
iwconfig $DEV essid 'Laptop WiFi'
iwconfig $DEV mode ad-hoc
iwconfig $DEV key s:mykey
ifconfig $DEV 10.0.0.1 netmask 255.255.255.0
/usr/sbin/dnsmasq --dhcp-range=10.0.0.2,10.0.0.10 -x /tmp/dnsmasq-$DEV.pid -i $DEV

Thank you very much for this hack, Daveba! Don't really need this as of now, but could be handy in the future. One, probably silly question, does it have any negative impact when connecting to a standard Wi-Fi router, or it just provides additional functionality?
Hopefully we can see this included in various Roms soon.

Well please don't credit me with the work. As noted in the first post, the initial patch was released for an older version of wpa_supplicant. I've just updated it for wpa_supplicant 6 and changed some aesthetics on the wifi list page on the phone. Remember again this is a hack and should really be inherently supported by the OS. I suggest people read issue 82 and star the issue for greater visibility.
I would like to know if anyone sees any negative impact with this hack. The only thing i see is that the phone doesn't automatically disconnect from the ad-hoc network if i take it down on my laptop or i move away from the signal range. It will drain the battery if not manually disconnected. This is a small 'bug' for what (in my opinion) is such a hugely important function. Hell even the iphone, the nokia E71, etc can do this out of the box and i get laughed at at work (until now).

TUN/TAP driver for openvpn available yet?

As the subject states, non of the current roms/kernels appear to have the TUN/TAP driver to run openvpn.
Side note.. ATT pissed me off today (okay so I had it coming for tethering but still..) So, new solution is to run openvpn and force all the traffic through my openvpn gateway, this will keep ATT from spying, and also prevent them from using TTL (still speculation, but one of the methods to detect tethering)

Just out of curiosity, how did you confirm that the TUN/TAP driver was non-existant or not operating properly on the skyrocket?
I'm in the midst of doing the same ... installing openvpn. I have the server set up on my home PC and verified through another laptop off-network. But I have problems when trying to run openvpn settings. Here is what I did:
1) Copied .ovpn file, ca.crt, client1.crt, client1.key, ta.key FROM server TO /sdcard/openvpn directory on skyrocket
2) Installed busybox
3) Installed openvpn installer
4) Installed openvpn using #3
5) Installed and opened openvpn settings
6) Under "OpenVPN Settings" I checked the box saying "OpenVPN"
7) Under "OpenVPN Configurations", I selected my .ovpn file's checkbox
8) The .ovpn checkbox immediately disables and I have no openvpn
Was your approach similar?

I just checked via lsmod. I did not bother going through the process of moving my config files from my captivate to the skyrocket.
Samsung does not include the tun/tap driver in the stock kernel, so it will require a custom kernel, or at least someone to create the module with the same libraries as the stock kernel and just the tun.ko module file to copy across to our current phones.

Actually TUN/TAP is compiled directly into the stock kernel and not compiled as a module so you won't find it with lsmod. You also don't need to do an insmod to use it. I'm running openvpn just fine in tap mode.
There IS a bug in the OpenVPN Installer though that requires you to have ifconfig and route in /system/xbin/bb. It won't work if you select anything else during the openvpn install.
Here's what I did...
Install busybox to /system/xbin
Install openvpn to /system/xbin and select /system/xbin/bb as the location of ifconfig/route
adb shell or use a terminal on the device and do a su.
mount -o rw,remount /dev/block/mmcblk0p24 /system
mkdir /system/xbin/bb
cd /system/xbin/bb
ln -s ../busybox ifconfig
ln -s ../busybox route
mount -o ro,remount /dev/block/mmcblk0p24 /system
Configure and start openvpn.

Good to know.
Will try it in abit, I tried to run openvpn, but it failed on the tun driver, which is why I stopped, but I did not link bb, will give that a try when I get a chance... stupid ATT busted me for unauthorized tethering again.. so cannot get my existing openvpn config from my server yet...

I tried the directions you provided but with using tun and no luck. I'll try and reconfigure my openvpn server to run tap and will try agian.

I just reconfigured my server over to tun mode and it's still working fine.
Can you try running openvpn from a command line and see what errors it spits out?

Also can you check if /dev/tun exists?

I had no problems getting it to work, I borrowed my co workers usb modem to pull down my configs from my old Captivate (I use ssl-admin and store the configs with the certificates in zip format).
The problem I am having at the moment is getting tethering to work while openvpn is running.
Laptop can talk to the phone (using wifi tethering, usb tethering kills the adb session, but I suspect it would work just fine), and phone can talk to the world, but laptop will not connect to the world.
The routes are in place, I checked the sysctl options, and ip forwarding is enabled. Just no traffic will pass... it is driving me nuts... heh.

Success for me too! Not sure what was wrong. The server was always working no problem and was always able to connect directly over home wifi from laptop. But I wasn't able to connect on the Skyrocket.
But I used gtj0's config file, changed the remote ip address/port, and worked perfectly. Thanks!
jvanbrecht: I haven't tried it with tethering yet and probably won't get to until at least a few days. Hope to be able to help by trying on my phone sometime soon.
Everyone: Any idea if it is better to run tun or tap for mobile phone openvpn? Regarding tethering, do both tap and tun hide detectable elements like TTL at the IP layer?
EDIT: VPN Not Porting Properly?
Hmm. It seems I am able to connect no problem and openvpn on the phone says it's connected. But when I go to www.whatismyip.com from my phone, it still says an AT&T address. I expected with openvpn running that it should show my home server ip address no? Also, openvpn on skyrocket indicates that it is connected as 10.3.0.6. But if I try to ping 10.3.0.6 from the server I get no response. Is that expected?

Success for me too! Not sure what was wrong. The server was always working no problem and was always able to connect directly over home wifi from laptop. But I wasn't able to connect on the Skyrocket.
But I used gtj0's config file, changed the remote ip address/port, and worked perfectly. Thanks!
jvanbrecht: I haven't tried it with tethering yet and probably won't get to until at least a few days. Hope to be able to help by trying on my phone sometime soon.
Everyone: Any idea if it is better to run tun or tap for mobile phone openvpn? Regarding tethering, do both tap and tun hide detectable elements like TTL at the IP layer?

TAP provides a bridged connection so broadcasts on the server's network are propagated across the connection. For network-to-network connections this may be needed for things like dhcp and windows networking. For end users, this usually isn't a good thing because it eats up bandwidth. TUN, which is routed instead of bridged, is the better way to go.
My config only routes traffic destined for the server's LAN over the vpn connection so the behavior you see with whatsmyip is normal. Check openvpn's config file paramters to make the vpn the default route for all traffic.

See my other post. I included my configs.
Just add redirect-gateway option to your client configuration, or the server side client configuration in the ccd directory.
I have everything working. As for what att will see. Only an encrypted tunnel initiated from you phone to your vpn server. Ttl, ip options etc will not be visible to att.

Cool thanks again. I'll try updating my configs and trying again tonight. I'm sure not being able to ping across the tunnel was probably a configure issue a well.

You also need the Client to Client option enabled if you want the openvpn server to advertise routes to other vpn client devices and their associated networks. That would be another reason why you cannot ping across the tunnel if you are trying to ping another vpn device.

jvanbrecht:
I'm not seeing your config files on the board here. I'm fairly new here so maybe I'm not looking at the right place. But I didn't see an attachment.

The configs are posted in my other thread.

Thank you. I'll try out the details in that post. If I have any questions I am going to post over there from now on because that post is more closely aligned with my goal and thus more relevant.

do you have a desktop or a laptop ..
if desktop then you should try some apps like reverse USB tethering ..which are very simple to use ..
there are too many apps like this which you can find on the play store ..

Thru Ethernet cable? If so change your modem to WiFi modem if using from data card use WiFi dongle search ebay

Well if you are on laptop...you can use this software known as Connectify to set up a Hotspot on ur laptop
You can do that with a wifi adapter on a PC too

Not at all
There are some reverse tethering apps to get ur pc's internet just by USB cable but they need a rooted phone!
Search on play store " reverse tethering"
If you don't wanna root....invest in a router...they are pretty cheap nowdays!

You can setup an ad hoc wifi network and share the internet connection to connected devices.
You can do it using the Control Panel or using the CMD.
In Windows 8 this functionality ist not available anymore using the GUI.
These commands should work on all windows pc's.
Replace ssid and key with your own if wanted.
Remember to open CMD with admin rights.
To configure adhoc network typ in CMD:
netsh wlan set hostednetwork mode=allow ssid=NameForMyNetwork key=MySecurityKey
Click to expand...
Click to collapse
To start adhoc network type in CMD:
netsh wlan start hostednetwork
Click to expand...
Click to collapse
To stop adhoc network type in CMD:
netsh wlan stop hostednetwork
Click to expand...

Open properties of your network adapter on PC and you'll find an option to share the internet connection of connected devices of the specific adapter.
Connect your Android over wifi to your PC, voila, you should be done if i did not forget something.......
EDIT:
Aaaargh.....just saw it by reading it the thread a second time....you have no wifi.
But anyway, maybe it helps somebody else.

A simpler way to go at it is a software called Connectify....completely gui based...I used to use it all the time on my laptop.....works on windows xp sp3 and up....

I Dont remember the original thread but here are the contents i got fromthat link a while ago...
@gilagamesh
Step 1: Connect your Android to PC by USB cable and enable "USB tethering". You are still allowed to enable this option even when your 3g/wifi on your Android is off.
- If you are using Linux (Ubuntu), you don't need to install anything. NetworkManager applet will try to establish a connection on the new detected wired network device.
- If you are using Windows, Windows will automatically search Windows Update and install driver for you. You can skip Windows Update search and install manually an already included driver from Microsoft. In Install Driver window, click Browse My Computer, then Let me pick..., select Network Adapters, uncheck Show Compatible Hardware, look at "Microsoft Corporation" at the left column, and choose Remote NDIS Compatible Device from the right column. You can install or update a driver from Device Manager in Windows.
- If you are using Mac, install driver HoRNDIS. You will be notified about a new network interface. Click "Network Preferences" in the dialog to add it to known interfaces list. Then "Apply".
- If you are using Linux without GUI or NetworkManager, run these commands as root (or use sudo):
Code:
ifconfig usb0 10.42.0.1 netmask 255.255.255.0
(suppose that you don't have any other USB network adapter, otherwise, your Android may be usb1, usb2...)
Code:
echo 1 > /proc/sys/net/ipv4/ip_forward
Command for sudo will be:
Code:
sudo 'echo 1 > /proc/sys/net/ipv4/ip_forward'
Code:
iptables -t nat -F
iptables -t nat -A POSTROUTING -j MASQUERADE
Step 2:
- If you are using Linux, click on NetworkManager applet at the top right of your screen, select "Edit Connections...". In tab "Wired", choose the new established connection (be careful, not Ethernet LAN connection) and click "Edit..." In tab "IPv4 Settings", choose "Shared to other computers" as Method. Click "Save". NetworkManager will reestablish the connection and assign to your PC an IP address on this USB network connection, default: 10.42.0.1. Leave Internet connections (wired or wireless) untouched.
- If you are using Windows, open "Network Connections" in Control Panel. It is somewhat different from setup in Linux. Right click on an Internet connection that you have. I assume that you are using a desktop which doesn't have any wifi adapter, so right click on LAN Ethernet connection with Internet, and select "Properties". In tab "Sharing" (or "Advanced" for Windows XP), click "Allow other network users to connect through...", then select the USB connection in dropdown list below. Click OK. Windows will automatically setup your USB network connection and assign to it an IP address, default for Windows 7: 192.168.137.1, default for Windows XP: 192.168.0.1. You can see your Internet connection is now "Shared" and your USB connection is now "Unidentified network".
- If you are using Mac, open System Preferences - Network. If you installed HoRNDIS, you will see a new network interface corresponding to your USB connection. With "Using DHCP" as Configure Ipv4, it may be already connected. Go back to System Preferences, click "Sharing". Select "Internet Sharing". Choose the Internet connection (Ethernet or Airport...) in "Share your connection from", and choose USB connection interface in "To computers using". Mac will assign to your USB connection interface an IP address, default: 192.168.2.1.
- If you are using Linux without GUI or NetworkManager, you have done all PC setup in step 1.
Your PC setup is now done!
Step 3:
Open Terminal Emulator on your Android. Type:
Code:
su
The command prompt must change from $ to #. If it does not, check to ensure that your device is rooted properly.
[UPDATED]Type the following command in Terminal Emulator, the same for all PC operating systems:
Code:
netcfg rndis0 dhcp
The name for usb interface inside Android may vary. It is usually rndis0 or usb0. Type
Code:
busybox ifconfig
to identify the name.
Use OLD instructions below when automatical dhcp method does not work.
[OLD]Type these following commands in Terminal Emulator:
For Linux PC:
Code:
ifconfig rndis0 10.42.0.2 netmask 255.255.255.0
route add default gw 10.42.0.1 dev rndis0
If route fails, try:
Code:
busybox route add default gw 10.42.0.1 dev rndis0
For Windows PC, use the same above commands, replace 10.42.0.2 by 192.168.137.2 (192.168.0.2 for Windows XP), replace 10.42.0.1 by 192.168.137.1 (192.168.0.1 for Windows XP)
For Mac PC, replace 10.42.0.2 by 192.168.2.2, replace 10.42.0.1 by 192.168.2.1
Now you can close Terminal Emulator and start the browser for Internet.
Some applications (download in Google Play, GMail, Facebook...) don't recognize Internet connection. You can try this way (WARNING: NOT TESTED):
- Enable temporarily 3G connection on your Android
- Type:
Code:
ifconfig rmnet0 0.0.0.0
The name for 3G interface inside Android may vary: ppp0, rmnet0... Type
Code:
busybox ifconfig
to identify the name.
before ifconfig rmnet0 ... above.
This will make applications see your Internet connection via USB as 3G!
And it works !!!

Yes it is to create a hotspot. And i wrote already that i read it to late that he has no wifi available.
