Windows 10: Windows 10 computer can't accept my WiFi password anymore, only connects via WPS and cannot...

I just had the system board replaced on my Lenovo Thinkpad P53s which runs Windows 10 Pro. When I try to connect to WiFi, it tells me to "Enter the network security key" because "Some information changed since the last time you connected. We need additional information to complete the connection." When I enter my Xfinity WiFi password, the computer attempts to connect and then gives me the same message again.


I repeatedly checked the WiFi password and confirmed that it is the one which all my other devices, including another Lenovo Thinkpad laptop, are running on. The computer is able to connect to a public WiFi network. It is also able to connect to my WiFi network if I tell it to "Forget" the network, restart the computer, and then connect to the network by pressing the button on the router. I believed this is called WPS and it automatically sends the password to my computer. Then the computer cannot reconnect after a restart or shutdown. I can see the password saved in the computer settings but it doesn't matter. I have to tell it to "Forget," restart, and set up again with the button.


I ran several troubleshooters with no results, and also confirmed that all my drivers are up to date. I've also reinstalled Windows since this started happening, due to other issues related to the system board being replaced. I ran some commands in the command prompt that were suggested to fix network connection issues. Unfortunately, they had no effect and the network connection issue remains. Please can you help me narrow down the cause of this problem and possible solutions? I've seen some forums suggest uninstalling and reinstalling a network adapter, but I don't know how to do that and it sounds risky to me.

How to connect to WiFi without using password?

Yes, you can connect to locked WiFi Without password by using the functionality of WPS (WiFi Protected Set Up). Most of the Routers support WPS function. For this trick, you must have physical access to the Router of WiFi network you want to connect to. If you are on Windows or Android device, then you are lucky, this trick will gonna work for you. Because Apple Ecosystem doesn’t support the WPS function.

You can do this in simple steps:

Step 1: Go to “Settings” in your Smartphone –> “WiFi” –> Go to “More” or “3 Vertical dot icon” and search for “WPS Push Button” option and just Tap on it.

Step 2: Now, Also Tap the “WPS” button on the backside of your Router. Within some seconds these both devices pair up and your device will connect to WiFi network. That’s It!!!

Try it.

Phone won't connect if I change wifi password

My Nokia Lumia 520 never had any connection problems, but today it won't connect not even when I press the WPS button on the modem or type the wifi password. I get the message:

''The Wifi network didn't respond, try again later''.

Wifi is working fine on all other devices (pc, laptop, tablet and other phones) so I'm guessing it's a phone issue? Phone's wifi was working fine yesterday.

 

Windows 10 upgrade problem, no input accepted

I really hate having to come here and ask for help, but I really am stumped. It hurts my geek pride. I have a PC with fairly modern hardware in it. It has a p8p67 pro in it. I have tried upgrading windows 10 on it twice now. Both times I have had the same result.

After windows finishes upgrading it goes to the log in/set up screen. I can't do anything. No keyboard or mouse input is accepted.

I will list some, or hopefully all, of the troubleshooting steps I have tried:

• Move keyboard and mouse to different USB ports.
• Try different keyboard or mouse.
• Restart computer, repeatedly.
• Google for related issues.
• Update Bios, because why not.
• Create boot media and revert to windows 7.

The windows 10 system restore boot media works fine with keyboard and mouse. All USB ports work in windows 7. I don't know what is wrong. I suspect that windows 10 is lacking a driver of some sort, but since the computer accepts no input I have no way of checking for which driver let alone installing it.

Please help me figure this out. If I have to revert back to windows 7 again, I am not going to get it upgraded to windows 10. Thank you in advanced.
