windows 8 no internet

Hi,

1. Try to ping google.com
2. if not then try to ping 4.2.2.2
3. see the "C:\Windows\System32\Drivers\etc" hosts file for any loop back ip configured.

I was able to ping 4.2.2.2. but not google so what does that mean?

Scanning with one tool for viruses does not mean no viruses. Get Malwarebytes (malwarebytes.org) and scan with that as well.

Try wired and wireless connections. Do both fail?

Reset TCP/IP to see if that helps.

Open cmd.exe with Run as Administrator
Then  netsh int ip reset c:\resetlog.txt
Restart the computer

Please let us know after the above steps.

Resetting TCP/IP may help the fact that you can ping but cannot resolve DNS (so cannot browse).

try to access http://74.125.236.39

if you are able to access then you need to check your LAN card DNS IP. put 4.2.2.2 and 8.8.8.8 as DNS server and check.

I've tried wireless and wired, reset tcip/ip/ tried static ip, tried the netsh resets.  I've also ran malwarebytes and it didn't find anything.

Next on the list then is System File Checker. Run SFC /SCANNOW and allow to complete. Restart the computer and test.

Look in C:\windows\System32\drivers\etc\hosts  as suggested above. Look for any entries that are not commented. Live entries could be preventing browsing. Live entries often come from viruses at some point.

what happens if you do the following:

-  Run nslookup and run the following commands at the chevron prompt:
     server 4.2.2.2
     ati.com

- If you get results shown below then it means your DNS is not working:


Microsoft Windows [Version 6.2.9200]

C:\Users\mohammed.khawaja>nslookup
Default Server:  google-public-dns-a.google.com
Address:  8.8.8.8

> server 4.2.2.2
Default Server:  b.resolvers.Level3.net
Address:  4.2.2.2

> www.ati.com
Server:  b.resolvers.Level3.net
Address:  4.2.2.2

Non-authoritative answer:
Name:    ati.com
Address:  165.204.85.63
Aliases:  www.ati.com

If DNS is the issue then change it to 8.8.8.8 which is Google or 4.2.2.2 which is Level3

ok, scannow could not repair some files and there are several it couldn't repair.  

the host file has

localhost name resolution is handled within dns itself.
127.0.0.1 localhost
::1 localhost

I did the nslookup and got back what you have shown.  I have changed the dns to google and level3 but it still won't connect.

are you able to  access http://74.125.236.39 ??

yes, 74.125.236.39 took me to google

Go to CMD and run IPCONFIG /FLUSHDNS

and try to access internet

Did you added 4.2.2.2 and 8.8.8.8 IP in DNS ?

I am using 4.2.2.2 and 8.8.8.8.  I flushed dns and still not working.

1. pls share the details how you are connected to internet. i.e your PC --> modem --->internet or something else.

2. Click Change adapter settings. select "Obtain DNS servers address automatically", and then check.

3.
ipconfig /flushdns

ipconfig /registerdns

4. if PC has DHCP IP then

ipconfig /release

ipconfig /renew

I have tried the computer both wired and wireless.  We have two other computers that are wireless that have no problem.  We are using a wireless router.  The computer that is not working was tried at someone elses house and it did not work there either.

I tried the ipconfigs with same results.

Hi,

Run the CMD as "Run as Administrator" and run following command.

netsh winsock reset catalog
netsh int ip reset c:\resetlog.txt


now, try to access internet.

Did the netsh changes and still the same.  

I saw other people on the internet with similar problems in windows 8, but no one ever had an answer.

reboot the system and check

its been rebooted, still the same.

Option 1:

Try clean Boot and see if possible 3rd party program could be causing this:

From the System:

Press the Windows key +R In the Run box type msconfig and hit enter

Under the Services  tab, place a check in Hide all Microsoft services and hit Disable all

Open Task Manager Under the Startup tab right-click and disable each Startup item and then close Task Manager Click Apply/OK

Restart

If you have connection now try find out which software caused this, try to reinstall it etc..

If the issues persist even after clean boot, (for testing only) try to disable firewall and Antivirus if any.

if still not works, follow this http://www.virusresearch.org/no-internet-access-in-windows-8-limited-connectivity/

Still not working.  Jeez, never had this much trouble getting a computer on the internet.

did you follow the instruction in last url as well ? (http://www.virusresearch.org/no-internet-access-in-windows-8-limited-connectivity/ )

I would not recommend refresh but rather an inplace-upgrade. With it, you don't lose installed applications.
But first please quote the output of the command
ipconfig /all

had to use the recovery disk

@TomBalla - Thank you and I was happy to help.
