Troubleshoot a Disconnected Internet Connection

print

If your Internet connection is down due to disconnection and you don’t know the reason for its cause, you would be approaching your ISP provider. Normally in India ISP providers have set up customer care so that they would help in any query related to your connection. So when your internet is down, the customer care executive would be suggesting you to go with the basic internet troubleshooting. This troubleshooting is to ensure that the problem is not in and around you. It goes with configuring your router and your internet connection settings.
Follow the steps mentioned below -

1. Unplug the power cable which is connected to the modem and OFF it for 10 seconds.


2. Connect the power cable to the router.


3. Connect a single PC to one of the LAN ports of the router.


4. Now restart your computer.


5. Now restore the router to factory default settings and it will remove all previously configured settings.


6. Once the router is restored it will reboot by itself.

Now the next steps is to confirm whether you are receiving the incoming signals or not. You can check IP address by following the procedure mentioned below and easily know whether you are receiving the incoming signals or not –

1. For all the operating system of Windows including Windows XP, Windows Vista and Windows 7, you need to go to run command (Windows button + R in windows 7) and cmd.


2. Now in DOS window type ipconfig and then press Enter on your keyboard.


3. This would give you complete details on the IP address, gateway address and subnet mask address.

The IP address that you see here would be near identical to that of you have for your router configuration except the end digit. For different router that you have you would get the following sets of IP address -

• For 3Com Router IP would be 192.168.1.x


• D-Link Router, IP would be 192.168.0.x


• Linksys Router, IP would be 192.168.1.x


• Microsoft Broadband Router, IP would be 192.168.2.x


• Netgear Router, IP would be 192.168.0.x


• Actiontec Router, IP would be 192.168.0.x


• Where x is a number assigned to the PC

Ex – I have D-Link Router and so I got the IP 192.168.0.124 which is depicted in the screenshot above.
Now when this is done, you can make a note of your IP address and check whether you are receiving the incoming signals from your router or the ISP provider. This is called as Pinging your ISP and it can be easily done by following the steps mentioned below –

1. Click on start and type your IP after writing Ping. Like in my case it would be ping 192.168.0.124 -t and then press enter. So in general it would be ping IPAddress -t.


2. This would open Ping command and with the TCP/IP connectivity results and it looks something like this -

If you get the above reply present in the message then your incoming signal is working fine but the problem would be in your PC or modem. If it shows ‘Local Area Connection not found’ then its the problem of internet service provider and you need to contact your provider.
