Windows 10: have strong wifi signal but cannot connect to internet VAIO Laptop/ xp

I have a VAIO laptop. It shows my wifi connection at bottom strong signal but cannot access internet on any programs It is xp and I used to get a signa at McDonalds when I would go form breakfast but at home not so lucky

Excellent wifi signal, no internet

I have comcast going into a netgear rt600 with an asus repeater upstairs. My iPhone is connected to the 5g signal. When I'm sitting outside I have full wifi signal but no Internet. Can't connect to anything. As soon as I go back inside its fine. How can I have signal but no Internet?

Are you sure you're connected to the same router inside vs. outside?

 

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.
