How to find out Your connection IP adress?
Your IP address is something you probably rarely think about, but it's vitally important to your online lifestyle. Without an IP address, you wouldn't be able to get today's weather, check the latest news or look at videos online. Why? Because without your IP address, websites like whatismyipaddress.com, CNN or ESPN wouldn't know where to send the information you asked for. They wouldn't be able to get it to YOUR computer.
Your web browser announces your IP address to any web site, so our website can find your IP address simply by listening for this announcement... So one very quick way how to find your IP address Click here or go to google search engine and just type "What is my IP".
How to Turn Your Ubuntu Laptop into a Wireless Access Point
Block Access to Unwanted Websites in Ubuntu
Want to block access to certain websites from your machine running Ubuntu or Linux Mint? It’s easy to do it by editing the host file.
With the hosts file, you can tell Ubuntu to redirect the specific websites to 127.0.0.1. So that the web browser returns below error:
sudo gedit /etc/hosts
Examples :-
127.0.0.1 www.websites1.com
127.0.0.1 www.websites2.com
127.0.0.1 websites3.com
127.0.0.1 morewebsites.com
How to fix your Internet connection in Ubuntu Linux
Check the basics first
Before you blame Ubuntu, try connecting to the Internet on other devices. If they're experiencing the same problem, it isn’t with Ubuntu—it’s with something else. For example, you may need to reboot your router, modem, or both. It’s always worth checking these fundamentals before delving into further troubleshooting.
Some laptops have hardware switches that can be toggled to quickly enable or disable Wi-Fi. If your Wi-Fi doesn’t seem to be working at all, check your laptop's hardware Wi-Fi switch.
If you’re using a wired connection, ensure the ethernet cable is plugged firmly into both the computer’s ethernet port and the router’s ethernet port. Sure, this may seem a bit obvious, but it’s easy to miss a bumped switch or loose cable.
Configure your connection settings in NetworkManager
NetworkManager connects to Wi-Fi networks and automatically configures wired network connections when you plug in an ethernet cable. Before NetworkManager, you’d have to do this with terminal commands.
If something isn’t working properly, you may still have to configure NetworkManager. Click the network connection or Wi-Fi icon on the panel at the top-right corner of your screen to access the NetworkManager menu, then choose a network. If you need to view information about your connection for troubleshooting purposes—your computer’s IP address, for example—click Connection Information.
If your local network connection isn’t working, ensure the Enable Networking and Enable Wi-Fi options are selected here in the menu. These options let you quickly disable and enable your connections, which is useful for putting your laptop into airplane mode. If you accidentally disabled either, you won’t have an Internet connection until you re-enable them.
Configure your connections by clicking Edit Connections. You’ll see a window with one or more connections, depending on how many network adapters you have in your computer. Select a connection and click Edit to modify its settings.
Ensure the ‘Automatically connect to this network when it is available’ option is enabled on the General tab. If it’s disabled, NetworkManager won’t automatically connect to a wired or wireless network when you boot your computer.
NetworkManager uses Dynamic Host Configuration Protocol (DHCP) by default, so your computer will attempt to get connection settings—IP address, DNS servers, and default gateway—automatically from your router or Internet service provider.
For networks that require a static IP configuration, you’ll need to visit either the IPv4 Settings or the IPv6 Settings pane and select the “Manual” method. (If you’re not sure which you’re using, you’re probably still using IPv4.) Enter the details your connection requires here—your ISP or network administrator can tell you what to enter if you don't know.
.
For more information about this Click here
Still If Internet is not working
follow below steps
nameserver 8.8.8.8
nameserver 8.8.4.4
If network manager fails
Sometimes the network manager becomes disabled after resuming from hibernation. If this happens, please create the executable script /etc/pm/sleep.d/55_local_networkmanager to solve this. Follow below steps to do that -
sudo gedit /etc/pm/sleep.d/55_local_networkmanager
Enter password and press Enter.
#!/bin/sh # This script gets NetworkManager out of suspend. case $1 in suspend|suspend_hybrid|hibernate) # No need to do anything here. ;; resume|thaw) #nmcli nm sleep false if [ "`nmcli -f state -t nm`" = "asleep" ]; then service network-manager restart fi ;; esac
- Now restart to see the working network manager.
How do I connect to a wireless network on Ubuntu?
-
To connect to a wireless network:
- Ensure that your wireless device is turned on.
- Click the Network Manager icon in the system notification area. If you are connecting to a network for the first time, security details may be needed. If so, a dialog box will open. Enter your security details as follows:
- In most cases the security type will be detected automatically. If not, select the security type from the Wireless Security drop-down box. This will depend on how the wireless network is set up. Examples of security types are WEP, WPA and LEAP.
- Enter the password, key or other authentication details as appropriate. These are usually case-sensitive. If you don't know your wireless key, it may be printed on the bottom of your wireless router.
- Click Connect. If you are prompted again for your security details, you may have entered them incorrectly, or there could be a problem with your wireless setup.
How do I connect to a wired (LAN) network on Ubuntu?
-
You will be connected to a wired network automatically when you plug in the network cable.
Manually entering your network settings
- Right click the Network Manager icon in the system notification area and click Edit Connections.
- Click the Wired tab, select the connection and click Edit.
- Click the IPv4 Settings tab and choose Manual from the Method drop down list.
- Click Add and enter your IP address and other details. Enter the address of your DNS server too.
- Click Apply. The network should now connect if you entered the settings correctly.
How to connect Datacrds in ubuntu
This is by far the simplest way to configure a USB modem to connect to internet. No additional drivers or software are necessary.

How do I connect to the Internet via a Wireless Data Card (Mobile Broadband)?
-
Mobile Broadband means any kind of high speed Internet connection which is provided by an external device such as a 3G USB stick or mobile phone with built-in HSPA/UMTS/GPRS data connection.
Most mobile broadband devices should be recognized automatically when you connect them to your computer. Ubuntu will prompt you to configure the device:
- The New Mobile Broadband Connection wizard will open automatically when you connect the device.
- Click Forward and insert your details, including the country where your Mobile Broadband device was issued, the network provider and type of connection.
- Give your connection a name (it is up to you what name you choose) and click Apply.
- Your connection is now ready to use. To connect, click the Network Manager icon in the top right of the panel and select your new connection.
- To disconnect, left click the Network Manager icon in the top right of the panel and click Disconnect.
-
If you are not prompted to configure the device when you connect it, it may still be recognized by Ubuntu. In such cases you can add the connection manually:
- Right-click the Network Manager icon in the system notification area and click Edit Connections.
- Select the Mobile Broadband tab.
- Click Add.
- This should open the New Mobile Broadband Connection wizard. Enter your details as described above.

Most of the data cards available in the market are designed to work on windows and mac computers. Few have drivers (software) to work on GNU/Linux too! However for the data cards that do not have GNU/Linux drivers, here is the most generic and simple solution..
1. Connect the data card to the USB port.
2. Open the 'Terminal' (Application → Accessories → Terminal)
3. Two additional software are required for this activity. So use internet (may be wifi or cable) to download these software packages. In the terminal window, at the $ sign, type sudo apt-get install wvdial and when prompted for a password, type in your login password (you will not see a thing on the screen, don't worry just key in your password)
4. The next software package that we have to install is call usb-modeswitch. This package is very important because most of the datacards when plugged in acts like storage devices and not datacards and this package switches the devices' mode from storage device to a datacard. You can download this package from http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-1.2.0.tar.bz2 and you'll need another file which can be downloaded from here http://www.draisberghof.de/usb_modeswitch/usb-modeswitch-data-20111023.tar.bz2. A supporting package called libusb is required too. This can be downloaded by typing sudo apt-get install libusb at the $ symbol in the terminal.
5. The two files downloaded needs to be unzipped (uncompressed). If you are not sure of where the files are, check your Downloads folder under the home folder. Right-click on the downloaded files and select extract here. Once this is done, go back to the terminal and type the following commands
cd ~/Downloads/usb-modeswitch-1.2.0
sudo make install (you'll have to enter your login password after this)
cd ~/Downloads/usb-modeswitch-data-20111023
sudo make install
sudo apt-get install libusb-dev
6. Now we need to configure wvdial. In the terminal at the $ symbol type sudo gedit /etc/wvdial.conf. This will open a text editor which might have some text in it. Replace the text with the following[Dialer Defaults]
Init1 == ATZ
Init2 == ATQ0 V1 E1 S0==0 &C1 &D2 +FCLASS==0
Modem Type == Analog Modem
Baud == 9600
New PPPD == yes
Modem == /dev/ttyUSB0
ISDN == 0
Username == <type your reliance number here> or internet (if it is a tata photon datacard)
Password == <type your reliance number here> or internet (if it is a tata photon datacard)
Phone == #777
Stupid Mode == 1
7. Once this is done, at the $ type sudo wvdial to connect to the internet
–> WvDial: Internet dialer version 1.60
–> Cannot get information for serial port.
–> Initializing modem.
–> Sending: ATZ
ATZ
OK
–> Sending: ATQ0 V1 E1 S0==0 &C1 &D2 +FCLASS==0
ATQ0 V1 E1 S0==0 &C1 &D2 +FCLASS==0
OK
–> Modem initialized.
–> Sending: ATDT#777
–> Waiting for carrier.

CONNECT
–> Carrier detected. Starting PPP immediately.
–> Starting pppd at Thu Nov 5 15:45:26 2009
–> Pid of pppd: 3205
–> Using interface ppp0
–> pppd: 0$P
–> pppd: 0$P
–> pppd: 0$P
–> pppd: 0$P
–> pppd: 0$P
–> local IP address 115.184.194.33
–> pppd: 0$P
–> remote IP address 220.224.141.145
–> pppd: 0$P
–> primary DNS address 202.138.103.100
–> pppd: 0$P
–> secondary DNS address 202.138.96.2
–> pppd: 0$P
You are now connected to the internet
8. You can start browsing now and remember not to close the terminal window. To disconnect you'll have to press Ctrl C. Back to Top

Back to TopTurn off Bluetooth by default in Ubuntu 14.04
Bluetooth is always on at each boot in Ubuntu laptops. This is not good, from both power saving and security purpose. Moreover, we hardly use Bluetooth, so why should have Bluetooth enabled by default? While one can turn off Bluetooth in one click in Ubuntu, doing it in each session is a repetitive and frustrating task. Simpler solution is to deactivate Bluetooth at start up in Ubuntu.
- Open a terminal (Ctrl+Alt+T) and and use the following command
sudo gedit /etc/rc.local
- enter password and press Enter.
- It will open the rc.local file. Just add the following line just before exit 0.
rfkill block bluetooth.
- Altogether, your rc.local file look like this:
- Save the file by clicking on save icon on top.
Note:Restart the computer and you should see that Bluetooth has been disabled. Of course you can turn it on when required by the Bluetooth indicator on the top panel. Back to Top
