I am on a MacBook Pro 2012 running macOS 10.11.
Recently, I have been having a problem with my Wi-Fi. Specifically, whenever I disconnect from one Wi-Fi network and attempt to connect to another in a different location, I get no internet. The signal says I am fully connected to the new network, but I cannot access the internet.
Restarting the computer solves the problem, but it is a pain to restart the computer every time I want to connect to a different network as I travel with my computer a lot.
I recently installed VPN software and suspect this may be the root of the problem because I never had this problem before the VPN.
Can anyone give me some ideas to fix this?
