Windows 7 Internet problem

Hello. I recently got my laptop back from repairs and reformatted it. Then I couldn't connect to the internet. But it sends and receives data(?). I tried wired but it wont work. I have built in wifi. I also have ubuntu installed and it connects to the internet just fine. I cant open a web page or do a system update.

Few things to try:

1. Restart the computer and try again.

Open IE
Tools tab > Internet Options > restore Advanced Settings and Reset Internet Explorer settings.
Restart IE.

1. right click on the cmd prompt and open as administrator
2. at the commend line type "netsh winsock reset"
3. Reboot.

Other options are:
1) Uninstall the Network adapter
Open Device Manager > Expand Network Adapter > Right Click on your internet network adapter and Uninstall
If it doesn't work, try it again and then reinstall the driver. You may have to get the new driver from the device website.

2) Winsock and Tcp/Ip Fix
Start > Run > Type CMD > Type the following:
Reset TCP/IP stack to installation defaults, type: netsh int ip reset reset.log
Press Enter > Type the following:
Reset WINSOCK entries to installation defaults, type: netsh winsock reset catalog
Push Enter

3) Run sfc /scannow
Insert your XP disc
Start > Run > Type CMD > Type the following:
sfc /scannow

From some other post:
I work for Dell "Your Tech Team" (Advanced / Premium consumer support) and came to this forum in hopes to find the resoultion on the problem in this subject. The recomendations on this forum were very helpful so I'd like to sumerize the logical items that should be done when one experiances this problem.

(Vista / Windows 7 - this summer is designed for people that have an intermediate understanding of the OS)

Going to try to list things in a logical order here from simplest first

* Check your network activity in the Network and Sharing Center - verify network connection is on

* Make sure the "work offline" is not checked in Tools menu or the registry is not set to work offline

* Disable all firewall software or manually add exceptions for Internet Explorer
* Verify IP address is appropriate and is set to recive an IP address automatically (

* Check Device Manager for conflics and errors (specifically under Network Adaptors)

* Reset Internet Explorer settings (

* Reset / Rebuild TCP/IP and Winsock library.
( - TCP/IP reset
( - Winsock reset

* Run a System File Check for corrupted OS files

* Uninstall ALL recent updates

* In safe mode run all malware / spyware / anti-virus scans possible
