If you have 3G modem, you can easily connect it to your precious RPi and have internet everywhere you go. This can be first step to turn your RPi into wireless 3G router or you can just do it to make sure, that wherever you go, XBMC would be able to download subtitles for the movie : So, here are step by step instructions… If you need to buy 3G modem, make sure that it is well supported by RPi — this article was tested using Huawei Verified peripherals can be found here. Now you can turn on RPi.
Now we need a client to connect to the internet — name of the program is sakis3G. If you also have problems see bottom of the article where I use wvdial. Since at the time when this article was created, web site www. From RPi shell you can download it like this:. Sakis3G is smart enough to read internet settings from your sim card — all you need to do is to point it to use the right connection setting.
In case for some reason sakis3G is not able to detect your internet APN setting you can enter in conf file all other necessary information.
In this case follow instructions from. First, we need to install wvdial:. Content of this file may be a bit different for some of you if it is, let me know but here is mine:. Section [Dialer Defaults] is automatically created when wvdial is installed. Let me try to explain what [Dialer play] config items mean:. Full list of options can be found here:. You need it to disconnect properly by issuing the following command:.
When I was testing this I realized that you should not be connected to the internet i. For some reason RPi would not get proper DNS even if you disconnect eth0 after you connect with the modem, so: first disconnect your lan cable and then connect.
Configuration for PLAY was found here. A 3G device broadcasts Internet signal through air waves instead of sending it using telephone or cable line. Thanks for your tutorial. I tried applying it to my Huawei E with Vodafone. The sim has a data-only subscription. It requires a pin-code to activate. I found a piece of wvdial. What more could I try?
Ask Ubuntu is a question and answer site for Ubuntu users and developers. It only takes a minute to sign up. Or you could search for "modemmanager" in the Ubuntu Software Center and remove it from there the title is "D-Bus service for managing modems". I found this had only a deleterious function when I tried the experimental version in Debian Sid and it failed to find my modem at all. That nearly doubled my speed and drops and failures became rare. I will probably remove it but for the time I want it to suspend function.

Check after disabling via: systemctl list-dependencies multi-user.The internet connection will be provided by a Huawei E USB 3g dongle on the safaricom network in Kenya, though the setup should be similar on most Huawei dongles and 3g networks. After a lot of reading and messing around, I've come up with a step by step guide for setting up my Pi as a wireless internet router. I use this every time I make a fresh setup of Raspbian, which is a fairly regular event. Stumbling round my latest install like a drunken elephant, it never takes me long to screw something up so badly that it's easier just to start from scratch.
As such, this guide assumes that the Raspbian operating system is 'fresh'. It has been tested with the release - as soon as I have the time free, I'll update the guide for the newest release.
So, the steps I use to set up the 'Pifi' Router are as follows: This guide and more like it can be found on my blog. Did you use this instructable in your classroom? Add a Teacher Note to share how you incorporated it into your lesson. Open a terminal window and type: lsusb should give an output similar to this: Bus Device ID Standard Microsystems Corp. I've highlighted the parts of the output that indicates the 3g dongle can be seen by the Pi. Yours should look similar to this, although it will vary from model to model - most 3g dongles on the market seem to be a Huawei of one flavour of another at the moment.
So long as there is a mention of 'modem' or 'UMTS', you should be laughing. This is an issue that arises because your 3g dongle has a small partition on it containing the 'dashboard' software for windows.
Your Pi has detected this partition, and labeled the dongle as a storage device before it had chance to notice the 3g modem waving its arms frantically in the background. This happened occasionally with my 3g dongle - I would suggest following the next step even if you are feeling smug about your lsusb output at the moment. The next time you reboot your Pi it could detect your dongle as a storage device, throwing you into a fit of depression. To install, in the terminal window type: sudo apt-get install usb-modeswitch The clue is in the name - its going to switch the mode of the usb device from 'storage' to 'modem.
You need to give it some direction though, which will require some googling. More information on USB identification can be found on the debian wiki.
Notice that the first 4 characters of the device ID vendor ID are the same in both examples, but the last 4 device ID have changed. Usb-modeswitch forces the operating system to use the combination that corresponds to the 3g modem. If your device has already been detected, you can find the Device ID in the output from 'lsusb' - the portion highlighted in the examples above.
Failing that, the search function of the usb-modeswitch forums. Your model number can normally be found somewhere on the device - try popping the cover off and looking for a sticker near where you insert the sim if you cant find it on the outside.
We can assume the first part vendor ID is correct in both situations. Amend the information to suit your own setup, deleting the bottom two lines if they are not needed - I'm not going to claim to understand the MessageEndPoint or MessageContent fields: They were part of the solution I found here - credit goes to krishnamohan of the fedoraforum.
Your device may or may not require them. Make sure to include the '0x' before the vendor and device IDs - this lets the Pi know that they are hexidecimal values. Reboot your Pi and run 'lsusb', observing the output - if you found the right Device ID, you should see something to the 'good' output example shown above.
The package can be installed via the terminal with the command: sudo apt-get install ppp Nothing further needs to happen with pppd, it should just sit there in the background, as a daemon is supposed to, waiting for Sakis3g to poke it in the ribs.Ever wonder what your Raspberry Pi was thinking?

Recently I have needed to find an emergency alternative to my broadband due to the regional wide area network, Digital Regionbeing shut down, and the ISP Origin making a mess of getting all their cutomers onto ASDL. In this setup all the computers are on a wired Ethernet connection using a switch for the network. IPv4 addresses are split into three different rangesthe Two other IPv4 address ranges are available for larger private networks : You will need a powered USB hub as the dongle can draw more power than the Pi can provide, the symptoms of too much of power being drawn will be the Pi behaving erratically or restarting unexpectedly.
The device ID is 19d2. If it is not, try removing the micro-SD card and rebooting the Pi, the device modes available are:.
When first plugged in the dongle was recognised as a ethernet device but it did not obtain an IP address:. Reboot, and you should see the obtained address:. The address We now need to give the Pi a static IP address on the internal network. This will assign IP addresses in the range I have also given my network printer a static IP address, it is still assigned by the DHCP server but never changes, the same would apply to any file servers and the like, I would assign static devices addresses that are outside your dynamically assigned range.

Reboot the Pi and then your test computer. Your test computer should now have an IP address The final part is to have the incoming traffic on the the Ethernet port eth0, go out on the dongle usb0.
This is achieved with iptables, a firewall and traffic router. This short bash script clears any old settings before applying the new rules:. Finally, you now need to have iptables reload when you start the Pi. I have used squid3 for this. The original is rather large, so you may want to make a copy and create a new one:. Many thanks for sharing this info. I substituted ppp0 for usb0 in my setup. Hello Rich, On the Pi, eth0 is the on-board Ethernet port.
You will need to assign a static IP address to eth0 as in the posting, or have whatever you are connecting to on your internal network to be running a DHCP server. Squid will only reduce the amount of data when you surf the web by locally caching some of the data. Having used Squid for a while now, the amount saved is very little. Any suggestions? Hello Karl, I wonder what this line means to? Hello Eko The dongle has a built in web interface.
It only takes a minute to sign up. Everything's fine. Since I want to automate this, I want to get rid of manually executing the mmcli command but am currently failing. One last thing: I am not searching for a solution using wvdial or other tools. I spent days trying to use them using "working" configurations from the Internet just to find out they are not working. ModemManager and NetworkManager have proven to work, so I'm just trying to complete the setup without building the ugly cronjob workaround.

I have found how to get NetworkManager and systemd-resolved working on Raspbian 9 Stretch. NetworkManager is very useful when you need to manage multiple VPN connections with split DNS, wifi networks and other advanced network settings directly from the Pixel Desktop. The network manager applet should appear after a reboot. Wicd is a network manager application wireless and wiredit a good alternative to Network Manager.

Without that, nmcli showed all my devices as "unavailable" and it couldn't control them. You don't actually need openvpn. This answer would be better without step 3. Step 3 is redundant and breaks the DNS.
