And no results
When connected to your router, go to AppleIcon>SystemSettings>Network>Wi-FI.
It should show the Router SSID name as being connected.
Select the "Details" button.
Does it show an IP address? Does it show the Router Address?
Are the first three digits the same or different?
Toggle the "Limit IP address tracking" off if it is turned on.
See if this helps or not.
In the side bar of the "detailed connection", select the TCP/IP button and then select the "renew DHCP Lease button. See if this helps.
If not, go back and select the "Forget This Network" button.
Then try and join the Wifi Router again.
You are going to need to input your WIFI router password again.
