delete wifi
When connecting to the wireless network, the notebook will save the information locally, but if the wireless network password is changed, the previously saved password=password cannot be connected, and an error will be reported.
If the notebook is a windows7 system, you can enter the control panel --> network and internet ------> manage wireless network , delete the wireless network and reconnect and enter a new password. But recently found that there is no option to delete the wireless network in the control panel of windows8.1. This can be solved by dos command line and netsh command.
win+r, enter cmd and press Enter
Enter and exit at the command line: netsh wlan show profiles to view my wireless network configuration files that already exist in the system
Enter netsh wlan delete profile name="Uncle Wang next door" (note the double quotation marks in English)
That's it. You can reconnect to the wireless network.
