Windows 10: Suddenly lost internet connection on laptop although tablet is still connected

I have an Asus vivobook 15 which, this morning, was working fine and then suddenly lost internet connection while my tablet and phone are still connected. I have tried various basic fixes, restarting the router, restarting my laptop and running the diagnostic tool on my laptop. The only problem that suggested was that there might be a problem with my Adapter but when I followed the link provided, it implies that my battery is low or faulty which is far from correct. I am happy to try various things but lack more than fairly basic knowledge how what to try next. Any advice appreciated. The lapt

W10 laptop won't connect to network, but Android tablet wilI

I run Windows 10 on an old Dell laptop. This afternoon, I suddenly lost my Internet connection. I keep getting a message asking for the "network security key," which is, apparently not the same as the password. However, my Android tablet (on which I'm typing this) is connected to the same network. I have a few interrelated questions:

1. Why would my connection suddenly drop out like this?
   
2. What is the "network security key?"
   
3. How do I fix this situation?
   

Please explain things step by step.

Thank you.

 

Connecting Laptop to the Internet, No connection

Trying to connect to the Internet using my Laptop. (not via the wireless router, but through the Ethernet cable)

My existing PC is connected to the Internet via an Ethernet cable, which is connected to the Broadband Modem (Virgin).

What I have tried to do, is take the Ethernet cable from my PC and connect it to the Laptop... Unfortunately, the Laptop isnt connecting to the Internet...

I have tried repairing the Network, with no success.

I am using the same cable, which was connected to the PC...

I do get error messages, when I click on repair in the Network Connection Tab. Its says it cannot assign an IP address.

I am Using Windows XP Home Edition.

I've tried using the Ping via cmd ping localhost or 127.0.0.1

I get the following results -

Packets: Sent = 4, Recieved = 4, Lost = 0(0%0)

Also done the following -

1. Start Internet Explorer.
2. Click the Tools menu, and then click Internet Options.
3. Click the Connections tab.
4. Under Dial-up and VPN Settings, click the broadband connection, click Settings, and then click Automatically detect settings.
5. Click OK.


..... with no luck

What do I do guys?
