Win 7 no internet....strange issue

Win 7 64 laptop
Wireless and Cat5....

Internet connection is good for all other computers...

Laptop will NOT access internet either wireless or wired...
IE and Chrome both affected...

Here is what i CAN do...
Ping websites, get good returns...Ping local host ok...

Here is what I have done....
Windows update downloaded files and installed while I watched...
but cannot get on internet....

Ran variety of virus scans...nothing of note...

Flush DNS...

Tried to do repair install but my Win7 CD is older than the installation....so Windows won;t update...
BUT while I was starting this process...Windows went out and updated the installation...then later it
determined my CD was too old...

Ran TCP repair...

Nothing in host file that is not supposed to be there...

Both wired and wireless connections appear normal...DNS from ISP...No proxy server set...

Network  and Sharing Center graphic show connected to internet...

Have valid IP and gateway...

I'm stumped...

Made an image of laptop so am prepared to reinstall Windows...but LOT's of programs to re-install...
Full Adobe CS5...so would rather NOT re-install if I can avoid it...

Anyone has any ideas / suggestions....
Thanks in advance

You might look at the Internet Explorer proxy settings (Chrome will probably use these settings too).
If you do not use a proxy server then "Automatically detect settings" should be disabled also.

Another option might be to temporary disable the Windows Firewall.

Thanks Zalazar...

No proxy settings in either IE or Chrome...
AVG is turned off...

Just turned Win firewall off...no joy...

Also...Safemode with Networking...still no internet connection...

Went thru all installed programs, nothing suspecious there...

Can you install the "Telnet Client" feature ?
and then from a Command Prompt (cmd.exe)
start telnet google.com 80

Open in new window

If the connection can be made then the new opened window should stay.

Zalazar....
Intersting idea...

Installed Telnet...ran it and the window is staying open...

Not sure, but I think this is telling me the same thing as doing a ping...

Both responses  mean "yes, there is internet connectivity at a low level"...
Just not at the browser level...

Test was successful...

Thanks for testing it.
So indeed, not only via ping (ICMP) but also via TCP the connectivity is functioning.

Steve MutchlerIT TechAuthor Commented:
Yes...that is correct...

And when I safemode with networking...it does not connect to internet either...

Device manager all looks good...

I don't think its a NIC or WLAN card driver issue...driver on one would not have an effect on the other...
So whatever the problem is...it is common to both...

Something in Windows seems to be the more obvious...

Did  sfc /scannow....no joy...

Anyplace I can download a late edition of Win 7 Home Prem I can burn to CD and use it
for a repair install...???

As this happens for both wifi and cat5 connection it is unlikely to be an adapter setting. TCP repair seems unlikely as you have connectivity but just no port 80 traffic. I would check IE and in Internet options do a reset to default settings just in case.

Does this happen for every user account on that machine. For example if you create a new user or log in with a different user (if you are on a domain) do you get internet?

I seem to recollect we having an issue like this quite some time ago as well and it was a fluke fix, I just cannot remember how.

I've faced this kinds of issue so many times.

Step 1. Check all of your adapters IP and Gateway settings once again and turn off all other interfaces except the interface using for internet connection. Check the connection and browsing status. If there's no good luck then probably that is viral infection.

Use Kaspersky Rescue Disk :

I used other antivirus software and didn't get success. Finally I used rescue disc and  had a good luck. I became to understand that Rescue disc doesn't depend on Windows but runs as a Linux OS from burned CD.

That's a very good URL for the Windows ISO's !

You might indeed try a repair or in-place re-installation.

Some other things but maybe you already tried:
• Temporary disable the real-time protection of the virus scanner.
• De-select "TCP/IPv6" on the Network interface.
• If Internet Explorer (IE) was upgraded to a higher version then you might try to un-install it, reboot the computer. Check if you can access the Internet with the older version of IE. If not, then re-install it.

Thanks for the input...

Gradually working thru your suggestions...

Nobus...downloading various Win 7 ISO's now...thanks for the link...I had it a while back and lost it...

Captain...only one user, I created another with admin rights...no joy on internet connection...
So...would appear not a profile issue...
I agree with both wired and wireless... issue it's not related to adapter settings...

Khandakar...I have the KAS rescue disk and I agree it is a very good tool...I did NOT try it in this case...intend to later today...although I don;t think it's a virus issue...I think it's a corrupted Windows file(s)....

Zalazar...thanks for sticking with me...I did unselect IPV6...no joy....I also set static IP on IPV4, no joy...then went back to DHCP...no joy...and remember, this affects BOTH IE and Chrome...so I don't thinks it's an issue particular to IE...

All things considered, when I get the ISO downloaded, I'm gonna try a repair install....see if that does it...

Many thanks for all the help...I'll report back in a few hours...

Thanks for checking the IPv6, a pity that it didn't help.
I actually mentioned IE because the installation does have an impact on the complete Operating System.
Good luck with the repair.

Try giving a static address, different from what you have and see if that works.

Steve MutchlerIT TechAuthor Commented:
Bill...I did that static IP thing...no joy...

Ok...here's the status...

Tried the repair install, it DID NOT WORK...the install went smoothly...everything came up as it should
BUT the wired and wireless did not connect up...

So...I wiped the HD, and did a full re-install from scratch...
It hooked up to the internet no problem...I got all my MSoft downloads...
Everything is working just fine...

Now....WHY...???
I was shocked that the repair install did NOT work....I really thought it would...

So....maybe some bad sectors in the HD...???
Or something in Windows was really screwed up without affecting anything else...

I'm back on my feet...will divide up the points...somehow...someway...

Many thanks for all the suggestions and ideas...I tried them all...

Peace

i have found that the repair only works when several rules are met (i don't know them) - and so, more often then it does work - works not at all.
i find it a real shame for MS

Nobus...
I used to do the repair install a lot with XP...and it worked more often then not...

This is only the 2ed time I've tried it with Win 7...I guess I expected it to work...

agreed- but this is Win7 - there's many compalints about this

Unless I missed one...each of the responders got points...
Equally divided...
I gave it a "B" because there was no solution...
I can change this is anyone deems it unfair...

Thanks again everyone....

Thanks for the points for something which wasn't solved by a change or fix.
Unfortunately with Windows it is sometimes difficult to troubleshoot certain issues.
Even if you would have taken an image backup before and would try to compare it to the current working installation, it would be very difficult to find out the exact cause.
Very good that everything is now working fine.
