Internet connectivity problems can occur for a variety of reasons to include corrupted networking software installation, third-party software inserting itself into the network adapter settings, misconfiguration issues with TCP/IP Winsock due to deletion or incorrect removal of software and removal of malware components. Below are some common (but simple) solutions which can help resolve connectivity issues. More advanced users may want to try NetAdapter Repair All In One, the Swiss army knife to fix common networking and winsock issues.

:step1: Sometimes just restarting a computer can restore a sudden lost Internet connection. Other times, the loss may be due to outages and disruptions within your ISP's network or the local tower. If using a satellite even extreme weather can cause a loss ot Internet connection. If rebooting did not restore the connection and there are no issues with your ISP, try to repair your Internet Connection with Windows Network Connection Repair & Troubleshooting Tool.

:step2: Reset and renew the IP address.

Press the WINKEY + R keys on your keyboard or click Start > Run and in the Open dialog box, type: cmd
* Click OK or press Enter. A dos Window will appear.
* To change to the ROOT directory (C:\>), at the command prompt type: cd \
* At the command prompt C:\>_, type: ipconfig /release
* Press Enter and reboot your computer.

.
If using Vista/Windows 7/8, use an elevated command prompt.
* Click the Start Orb and in the Search box, type: cmd
* Right-click on cmd.exe and select Run As Administrator (or use Ctrl+Shift+Enter).
* Click Yes if prompted by the User Account Control.

Alternatively, click the Start Orb > All Programs > Accessories, right-click Command Prompt and select Run As Administrator.
* At the command prompt C:\>_, type:ipconfig /release
* Press Enter.
* When the prompt comes back, type: ipconfig /renew
* Press Enter.
* Close the command box and and see if that fixes the connection. No reboot needed.

 
:step3: Flush the DNS resolver cache and register.

Press the WINKEY + R keys on your keyboard or click Start > Run and in the Open dialog box, type: cmd
* Click OK or press Enter. A dos Window will appear.
* To change to the ROOT directory (C:\>), at the command prompt type: cd \
* At the command prompt C:\>_, type: ipconfig /flushdns
* Press Enter.
* At the command prompt C:\>_, type: ipconfig /registerdns
* Press Enter.

.
If using Vista/Windows 7/8, use an elevated command prompt.
* Click the Start Orb and in the Search box, type: cmd
* Right-click on cmd.exe and select Run As Administrator (or use Ctrl+Shift+Enter).
* Click Yes if prompted by the User Account Control.

Alternatively, click the Start Orb > All Programs > Accessories, right-click Command Prompt and select Run As Administrator.
* At the command prompt C:\>_, type:ipconfig /release
* Press Enter.
* When the prompt comes back, type: ipconfig /flushdns
* Press Enter.
* You will get a confirmation that the flush was successful.
* At the command prompt C:\>_, type: ipconfig /registerdns
* Press Enter.
* Close the command box.

 
:step4: Most Internet connectivity problems arise out of corrupt Winsock settings due to the installation of a networking software or Malware infestation. This can usually be fixed by resetting the winsock.

Press the WINKEY + R keys on your keyboard or click Start > Run and in the Open dialog box, type: cmd
* Click OK or press Enter. A dos Window will appear.
* To change to the ROOT directory (C:\>), at the command prompt type: cd \
* At the command prompt C:\>_, type: netsh winsock reset
* Press Enter and reboot your computer.

.
If using Vista/Windows 7/8, use an elevated command prompt.
* Click the Start Orb and in the Search box, type: cmd
* Right-click on cmd.exe and select Run As Administrator (or use Ctrl+Shift+Enter).
* Click Yes if prompted by the User Account Control.

Alternatively, click the Start Orb > All Programs > Accessories, right-click Command Prompt and select Run As Administrator.
* At the command prompt C:\>_, type:netsh winsock reset
* Press Enter and reboot your computer.

If needed, type these commands, one line at a time, pressing Enter after each.
netsh int ipv4 reset
netsh int ipv6 reset

You can also reset the TCP/IP protocol to its default state with this command, then pressing Enter.
netsh int ip reset

 
:step5: In some cases third-party software (good and bad) will insert itself into the network adapter settings. If not removed properly or inadvertantly removed by security tools, loss of connectivity often results.

:step6: Check/reset your network settings and Configure TCP/IP to use DNS.
* Go to Start > Control Panel, and choose Network Connections in XP or Network and Sharing Center > View or Manage network connections in Vista/Windows 7.
* Right-click on your default connection, usually Local Area Connection or connection that you want to change, and and choose Properties.
* Double-click on Internet Protocol (TCP/IP) or highlight it and select Properties in XP.
* Click the Networking tab, click either Internet Protocol Version 4 (TCP/IPv4) or Internet Protocol Version 6 (TCP/IPv6) in Vista/Windows 7/8, and choose Properties.
* Under the General tab, write down any settings in case you should need to change them back.
* Select the button that says "Obtain an IP address automatically" or make sure the DNS server IP address is the same as provided by your ISP.
* Select the button that says "Obtain DNS servers automatically".
f598cd96-6bf9-47be-942d-7d0b0afdbd88_47.
.
* If unknown Preferred or Alternate DNS servers are listed, uncheck the box that says "Use the following DNS server address".
* Click OK twice to get out of the properties screen and restart your computer. If not prompted to reboot go ahead and reboot manually.

CAUTION: It's possible that your ISP (Internet Service Provider) requires specific DNS settings here. Make sure you know if you need these settings or not BEFORE you make any changes or you may lose your Internet connection. If you're sure you do not need a specific DNS address, then you may proceed.

Thanks for your reply. I have applied all of them but neither of them helped to resolve the internet problem.

Internet is working fine on other devices so no there's no problem with ISP.

Press the Windows key + R to open a Run box. Copy/Paste the following command:
 

regedit /e C:\Look.txt "HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CurrentVersion\Internet Settings"

Press Enter.

You won't notice anything. However, it will have created a report on your C drive named Look. Attach that file to your next reply.

I forgot to include this at the end of Step 4.

If needed, type these commands, one line at a time, pressing Enter after each.
netsh int ipv4 reset
netsh int ipv6 reset

quietman7, I have also applied that but all in vain.

Finally I fixed the problem my doing some research. I found the solution here
http://answers.microsoft.com/en-us/windows/forum/windows_7-hardware/windows-couldnt-automatically-bind-the-ip-protocol/a2f074cf-be62-435e-b951-42dfbb9351c2?page=2

And here is the solution. It might save someone's alot of time.

It turns out there was some third party software inserting itself into my adapter settings. 

Here's how I fixed it:

Go to Control Panel> Network and Internet > Network Sharing Center 

Click 'Change adapter settings' in left pane.

Right click your adapter. Select 'properties'.

There will be a box headed 'This connection uses the following items.'

Uncheck anything that looks like it was installed by a third party (AVG, Avast, ZoneAlarm). In my case the culprit was 'HTC NDIS Protocol Driver' which was installed by my cell phone software (HTC). Since it might not be obvious what to uncheck, here is what I currently have checked in my working system that should not cause a problem:

KEEP THESE CHECKED:

Client for Microsoft Networks
QoS packet scheduler
File and Printer Sharing
Internet Protocol v6
Internet Protocal v4
Link-Layer Topology Discovery Mapper I/O driver
Link-Layer Topology Discovery Reminder

Uncheck everything else. 

Go back to the Network and Sharing menu, disable and re-enable the adapter.  That should work. 

I hope it will help somebody. Thanks for your help. Cheers!
