Hi I had formated this laptop a few months ago and after the internet explore wouldnt connect anymore but the firefox would so I've been useing that browser but now it wont connect anymore, my other laptop connects fine, i have att universe wireless. It seems like it happened when i installed some windows updates the other day so i deleted those but it still wont connect, i also tried system restore several times going farther and farther back but it always said and error occured. when i right click the connection icon and choose repair it runs and then says a problem that cant be repaired automatic and i need to contact my provider. Doesnt make any sence to me, can anyone help? thanks

 

See if the steps in this video will help.

Reset A Wired Or Wireless Internet Adapter In Windows

Also check to be sure the wireless switch on the laptop is in the on position.

Have you tried connecting to the internet using a wired connection to the router?

 

didnt try a wire connection but watched the video and tried that stuff no results. again when i try system restore it does not work and says no changes were made, that there was an error. i went through stuff and tried to make internet explorer and firefox my default browser, still wont connect and again the icon on the bottom right says im connected?

 

Click on Start, and then in search box, type ncpa.cpl and press Enter

Network Connections window should open.

Right click on your Wireless Network icon, and select Properties

Scroll down and double click on Internet Protocol [TCP/IP]

Make sure that the two boxes are checked to
Obtain IP address automatically and Obtain DNS server address automatically

Restart the computer and check your internet connection again.

Why did you format your laptop? Do you mean that you reinstalled the original factory image?

From your previous posts, I'm assuming this laptop is your Acer 5515. Correct?

 

ok there were two version of internet protocal, 4 and 6. 4 was set right but 6 had the one checked to use some address in the boxs so i changed it like you said and now firefox is working but internet explorer still wont connect, i did go through some things and checked boxes to make firefox my default browser. I formated or should i say reset the computer back to factory cause the hard drive was full and just running bad, its been good till this problem.

 

Progress! Good work!

Now try the AT&T U-verse troubleshooter for IE.

AT&T U-verse Internet Explorer Troubleshooter

Choose "Can't Browse" from the list of topics, and then Internet Explorer.

For your problem with System Restore, try shutting it off. Then reenable it. The old restore points will be deleted. They aren't useful anyway because of the Windows updates.

Manually initiate a new restore point. If it says restore point completed successfully you are good.

 

man this computer changed it back so i couldnt connect again, i went back in and fixed it again then did the system restore off on and created a new and only point, said it worked, then went to att but they say this feature is having problems so illl try it again later

 

ok now i notice eveytime i restart this computer the one setting in ncpa.cpl changes back and i cant get online until i go back and change it. I updated the mozilla to the lateset version too. when i open it i get a error about adobe flash player 16 so i deleted that but still haveing this problem.

 

Let's wait to see what AT&T U-verse has to say about the IP and DNS server addresses.

 

ok used that att link did the test part of which had me check settings in tools on the ie browers which were set right except one was grayed out but it was checked so they said for me to contact microsoft or use their paid support

 

Did you talk with a human? No explanation for failure to connect or the changing IP and DNS addresses?

Do you have the malwarebytes program on your computer?

Have you done any malware scans since this problem cropped up?

 

yes to all of that, even a supervisor from att called me, just wanting me to use their paid service. i'm sure its someting in my computer as this lap top i'm useing has no problems at all

 

With your automatic IP and DNS settings, and with Firefox working, go to the link below and download version 3.0.8 of TCP Optimizer from the speedguide.net mirror.

SpeedGuide TCP Optimizer

It is a standalone portable executable file that does not install the program on your computer. Run the downloaded tool and on the File menu, Click Reset TCP/IP and then Reset Winsock, then close the program.

Reboot the computer and see if there is any improvement.

 

i tried it and it said all resets failed and no user settings to be reset

 

Run a SFC scan from an elevated command prompt. This link will provide instructions.

Use the System File Checker tool to repair missing or corrupted system files

 

well thanks for all your help but i got internet explore working again by opening both computers internet options and matching what was checked on my dell to my acer and now its working fine. I couldnt use that last cmd as i dont have the administrator password but i guess it dont matter at this point, so thanks again.

 

All that counts is that you got it going. That is good news. Thanks for the follow-up.
