Resetting TCP/IP settings in Windows
Sometimes only a TCP/IP stack reset can fix an internet problem. Microsoft created a tool that does it automatically, or you can reset TCP/IP manually.
Microsoft Fix it
The "Microsoft Fix it" tool helps you reset TCP/IP settings in Windows 7.
Resetting TCP/IP manually
To reset TCP/IP manually:
- Press "Start" and type
cmdin the search bar. Right-click cmd in the results and choose "Run as administrator". - In the command prompt type and run:
netsh int ip reset logfile.txt
This command resets TCP/IP settings and saves the changes to a log file (logfile.txt) in the current directory. You can also specify a full path, e.g. c:\logfile.txt.
Restart the computer for the changes to take effect.
Additionally you can flush the DNS cache with: ipconfig /flushdns
