information   Information
This is your one-stop internet related issues guide. Here I will show you some ways to fix your high speed or dial up internet connection issues with Windows 7.
Note   Note
I will show you some very useful and basic steps that you can follow without having much technical expertise. All you have to do is identify your issue and follow the troubleshooting according to it.
warning   Warning
I do not guarantee that it will 100% work for you. However, these methods have been tried and tested and has worked 8/10 times. So try your luck.




Here's How:

Step 1: Identify your internet connection:

A: Do you have a high speed connection or a dial-up connection?
  • If you use a telephone line and connect it to your computer and dial the connection, you have a dial-up connection.
  • If you have a router or a cable/DSL modem with an ethernet cable connected to your computer, its a high speed connection.
Step 2: Troubleshoot the issue.
Note   Note
To fix internet issues related to high-speed connection, follow these steps:


When you Cannot Connect to internet using a high-speed or broadband cable connection.

Check your IP Address.
Click Start and in the Start Search box, type cmd and press Ctrl+Shift+Enter.
Now in the black command prompt window, type ipconfig /all

Look for Ethernet Adapter Local Area Connection.
Look for IPV4 Address. If its anything other than 169.254.xxx.xxx, you have a valid IP address.
For any other ip address other than 169.254.xxx.xxx, follow these steps:
information   Information
Now that you've diagnosed that you have a valid IP address, its time to diagnose the issue.
A: In the same black command prompt window, type
ping <Default Gateway> and press Enter.
(See the screenshot below).

Now look at the ping statistics, it should send 4 packets and receive 4 packets. Sent=4, Received=4, Lost=0.

B: If the ping is successful, type
ping Google and press Enter.
(You can type the address of any website like Yahoo! to check the connectivity).
(See the screenshot below).

If the ping is again successful, your Anti virus or firewall program is blocking your internet connection. By pinging Default Gateway and websites, we check the internet connectivity of the computer with ISP and websites respectively.

information   Information
Now that you've diagnosed that the ping is successful, its time to troubleshoot the issue.


  • If ping to Default Gateway and website is successful but you cannot browse any websites:
Temporarily disable/remove your antivirus program and your internet will start working.
Note: You can also boot to safe mode with networking to check the internet connectivity. (Press F8 when you turn on your computer and select Safe mode with networking option to boot the computer to safe mode with networking).

  • If ping to Default Gateway is successful but pinging websites returns an error and you cannot browse any websites:
In the same black command prompt window, type the following commands and press Enter after each command:
Ipconfig /flushdns
Ipconfig /release
Ipconfig /renew
Now restart your computer and try to browse to some websites like yahoo,google, etc.

Note   Note

Internet connection problems

Hallo everybody.

I am using Windows 7 64 bit version connected to an High speed connection.
The sytem did install 2 differend programm directories, one 32 bit and one 64 bit.
Also two IE8 versions.

The IE 8 64 bit version works fine.( and fast like H....ll )

The IE 8 32 bit does not connect to the internet.( Not at all)
I did check all settings and as far as I can see they are all the same.

Non of my 32 bit programms can enter internet and the system does not allow me to copy all the 64 bit files over the 32 bit files.

If I use this sample which system are I looking.
The 32 bit or the 64 bit ??

Regards Cees

Hi cvk, this troubleshooting applies to both 64bit and 32bit. Well yours is a wierd problem as its happening will all 32bit programs.
Also, you wont be able to copy 32bit items to 64bit program files folder. Have you tried any other browser like firefox?

Hi, dinesh.

I did try to copy my programm files to the 64bit area.
Same result. Somehow these 32 bit programms are directed to the 32bit browser.

I did try every combination with directories ect.
What I do not like in this --- is that I am not in controle of my programm.
It is not possible to delete EI 8 32bit. I do not have permission.
What ever I try the "SYSTEM" does not let me change/move or delete the IE 8 32bit system.

This 32bit strugel is maybe the case of HOMENETWORK not willing to work.
I do get an error but if I let Windows 7 look for the cause it comes back with
Nothing wrong found.

I realy hope this is not a 64bit problem.
