Diagnostics via command line and resetting settings
When visual methods fail, command-line tools come to the rescue. They allow you to perform a deep reset of network stacks and clear the DNS cache, which often contains erroneous entries that interfere with the connection. This method is especially effective if the laptop can see the network but cannot obtain an IP address.
Run the command prompt as administrator. To do this, enter cmd In the search box, right-click on the result and select the appropriate option. In the window that opens, you need to enter a series of commands in sequence, pressing Enter after each one. This will restart network services and reset the TCP/IP configuration.
| Team | Purpose | Result | Need to reboot |
|---|---|---|---|
netsh winsock reset |
Resetting the Winsock catalog | Fixes network access errors | Yes |
netsh int ip reset |
Resetting the TCP/IP protocol | Restores default IP settings | Yes |
ipconfig /release |
IP lease cancellation | Frees the current address | No |
ipconfig /renew |
Renewing IP address | Requests a new address from the router | No |
After all commands have been executed, a message about successful completion or a request to restart the computer will appear. It is critically important to reboot after the Winsock reset command., otherwise the changes will not be applied. This action often solves problems when other methods fail.
