Flush DNS
Our office WIFI recently changed settings.
I can connect to the network but no internet access.
The auto settings are using the old gateway, and dns settings.
I attempted these possible solutions.
Put on airplane mode then back - no effect
Forget network - no effect
Tried renew lease - no effect
What is the best way to erase the old settings and enter the new ones?
