Could be that the laptop has the problem, what I have done to correct these things if it's fixable is simply go into device manager and uninstall the networking controller and reboot. Letting windows reinstall it. If that doesn't work it may very well be a bad network controller. Or try this when all else fails: reset tcp/ip
- To open a command prompt, click Start and then click Run. Copy and paste (or type) the following command in the Open box and then press ENTER:cmd
- At the command prompt, copy and paste (or type) the following command and then press ENTER:netsh int ip reset c:\resetlog.txt
Note If you do not want to specify a directory path for the log file, use the following command:netsh int ip reset resetlog.txt
- Reboot the computer.
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:
To run the manual command successfully, you must specify a file name for the log, in which the actions that netsh
takes will be recorded. When you run the manual command, TCP/IP is reset and the actions that were taken are recorded in the log file, known as resetlog.txt in this article.
The first example, c:\resetlog.txt, creates a path where the log will reside. The second example, resetlog.txt, creates the log file in the current directory. In either case, if the specified log file already exists, the new log will be appended to the end of the existing file.
