Not the recent w10 upgrade then.
Open a command prompt window and try the following 2 commands
note there is a space between ipconfig and the forward slash in both cases.
There was a problem with W10 updates. Microsoft said that if you "restart" your computer it should fix it. Use the "restart" option not "shut down" then a re-start.
A few things to check if that doesn't reslove the problem:-
It could be that your computer has IPv6 selected. Try disconnecting it as follows:
In the search field type.ncpa.cpl and press enter.
In the new window right click on your wireless network connection and select properties
In “This connection uses the following items” section remove the tick beside Internet Protocol Version 6 (TCP/IPv6) then press OK
Left click on Internet Protocol IPv4, click properties . Check the options to obtain IP address and DNS server address automatically.
Once done try and connect to internet.
If that doesn't help it might be that your TCP/IP stack has got corrupted. To reset it, open a command prompt with administration access, and type the following commands
Restart your computer try connecting.
If that did not help open the command prompt with admin access again and type in this command: sfc /scannow
It will check the Windows files and will fix any problems it finds.
