Windows 10: Not reading Wifi signals as strong as usual.

Hello-I'm not sure if it is the Windows 10 software or the HP hardware but ever since I got my HP Pavilion laptop/tablet back from the repairman who replaced the touchscreen my computer won't connect to it's usual strong Wifi connections.

The connections show up but as barely 1-2 bars of strength. What would cause that? Software or hardware issue?

Thanks for your time, Truly.

wifi signal fluctuates

My wifi signal strength was working good when i bought my lumia 640xl...bt since i upgraded to win10...the signal fluctuates even though on my pc and other devices at my home the signal strength is strong...please suggest a solution...thank you

 

Wifi cannot connect even though signal is strong.

After I updated my window, my usual wifi connection is errored. I get a message when trying to connect, "Some information changed since the last time you connected. We need additional information to complete the connection".
And asking to put the network security key. But I didn't do any changes to my router or network. So I put the wifi password but it doesn't connect at all. The strange thing is this problem won't happen when the
laptop is in the room where the router is placed. It only happens when I try to connect the wifi from outside of that room even if the wifi signal is strong. But after the wifi is connected in that room, the
connection won't be disconnected even if I move my laptop to other rooms. So every time I restart my laptop, the problem repeats again and I need to go back to the room where my router is placed.

I already reinstall/update my wifi adapter driver and restarted the network but the problem cannot be solved yet.

Please is there any way to solve this problem so that I don't need to do this tiresome process to connect the wifi.
