INTERNET NOT WORKING BUT YOU HAVE PING
########################################
Lets say your browser is not working to get a website up.
But you can ping www.google.com so obviously internet works
If you cant get to ping www.google.com but you can ping 8.8.8.8 then fix DNS first:
if dns messed up:
#################
Start->Run->cmd … enter
ncpa.cpl …. press enter
Go to the properties of your adapter (wireless or wired) that gets you to the internet, and go to IPv4 settings. Check your dns settings, set them to:
8.8.8.8
4.2.2.2
The settings will work for now (its okay to change them, they are just a phone book) – they are also good permanent settings unless your set on using OpenDNS or something
ipconfig /flushdns …. press enter
ipconfig /registerdns …. press enter
ipconfig /displaydns
If you have norton
####################
uninstall norton, it can fall into a situation where it blocks internet browsing. Use AVG instead. The Free AVG.
Reset your winsock and tcp/ip protocol
#######################################
netsh winsock reset
netsh int ip reset resetlog.txt
When you reset the interface ip (tcpip stack) it wants a log file, it will save to the relative or absolute path.
When you run the reset command, it rewrites two registry keys that are used by TCP/IP. This has the same result as removing and reinstalling the protocol. The reset command rewrites the following two registry keys:
SYSTEM\CurrentControlSet\Services\Tcpip\Parameters\
SYSTEM\CurrentControlSet\Services\DHCP\Parameters\
Ensure proxy is off
#####################
step1)
Open Internet Explorer, click “Tools” and then click “Internet Options.”
step2)
Click the “Connections” tab and then click on “LAN Settings.”
step3)
Uncheck the box marked “Use a proxy server for this connection” and then hit the “OK” button. The changes you made will be immediately applied and IE will no longer use a proxy server to connect to the Internet.
Step4 – added by me)
Make sure the settings that says “Automatically detect settings” in the Automatic configuration section is checked to on.

Check if proxy is off
######################
Even though the proxy setting thru IE->Lan settings could be turned off, double check its turned off and ensure it by doing these settings via regedit:
You can try it yourself as follows:
1- Close IE
2- Run regedit
3- Goto HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings
4- Change AutoConfigProxy Key name into some garbage name like 000AutoConfigProxy000
5- Change ProxyEnable Key Value into 0
6- Leave blank the Proxyserver Key Value (Don’t delete the key, just make its value blank)
7- Change MigrateProxy key value into 0
8- Close regedit
9- Run IE
It should work now.
Make sure to delete all of your adware stuff
