question:
The network was suddenly disconnected at home, and the following optical modems and routers were restarted. As a result, there was no password, so a router wifi password was reset. However, mobile phones and ipads can be connected, but the laptop keeps displaying "Unable to connect to this network", and the new password cannot be re-entered.
Solution:
Possible solutions found online:
1. In This Computer-->Management-->Service-->WLAN Autoconfig, restart WLAN Autoconfig and set it to automatic.
2. Network and Sharing Center --> Change Adapter Settings --> Right-click "WALN" --> Diagnosis
However, it didn't work. . . .
It is definitely not a hardware problem that the notebook can see the nearby wifi; other devices can connect to the wifi, and it is not the reason of the router network;
So，
Find a way to make your computer able to enter a new password! ! !
3. Last resort
Start-->Settings-->Network and Internet-->WALN-->Manage Wi-Fi Settings--> WiFi you want to connect to -->Forget -->Re-enter the password to connect to WiFi
Later learned that win10 has a memory function. After connecting to this wifi network for the first time, the wifi password will be saved automatically. When the wireless network password is changed, w
in10 still uses the old password, so there will be an error that it cannot connect to this network.
