Sometimes, it happens, the Internet connection settings get lost or simply does not want to connect to the network (does not receive an IP address via DHCP). Similar problems may arise as a result of the operation of some malware(viruses). You can torture those for a long time. support from your provider or call a specialist at home. You can try to fix the problem yourself.
To reset TCP / IP in operating rooms Windows systems NT (2000 / XP / Seven) exists special program netsh.exe.

netsh.exe- (Network Shell) allows you to configure the network parameters.

Some dirty viruses will get into WinSock and dirty.
Symptoms:

• The download speed of files over TCP is very low (while over UDP it can download quickly);

• When you turn on the computer for a while, a couple of minutes, the Internet works fine, but then it disappears completely (the speed drops to 0);

• The Internet works and the download speed is normal, but the uploaded file turns out to be broken because it is not downloaded completely (most likely the virus intercepts some of the packets during transmission, but sends a notification to the source about the successful receipt of all packets).

In addition to viruses, you can also "break" your Internet connection (or "shut it down")

Some examples:

• The computer does not receive an ip-address automatically (via DHCP);

• IP addresses are pinged but not pinged by name;

• The computer receives an IP address of such a pattern 169.254. *. *;

If the viruses are cleaned, then you can proceed with the recovery. ATTENTION! The following procedures will reset the network settings. I highly recommend rewriting the settings.
What would reset Winsock:

If the first command does not solve the problem, you can reset the TCP / IP stack to "factory" settings:
Ibid in command line, enter the command:

netsh int ip reset c: \ resetlog.txt

In this case, the reset log will be saved in the root of the C: \ drive; if you omit the c: \ prefix, the log will be saved in the current directory. After that, you should restart your computer.

After using this command, the following register branches will be reset to the "factory" ones:

SYSTEM \ CurrentControlSet \ Services \ Tcpip \ Parameters \
SYSTEM \ CurrentControlSet \ Services \ DHCP \ Parameters \

You can use these commands together one after the other. By the way, they also dump the DNS cache.
About DNS Cache Issues: For example, the site has moved to another hosting, as a result, its IP address has changed. And since you have not quite fresh data in the cache, when you enter the site name, you will be taken to the old IP address, where the site no longer exists.

In order not to reset all settings, try the command ipconfig / flushdns If it doesn't help, use netsh int ip reset resetlog.txt- this is guaranteed to help and reset everything it touches network connections.
