Hi there, I'm not an informatics expert so I don't really know what should be the proper category for this thread. I have a MacBook Pro (Retina, 15-inch, Mid 2015) with MacOS Mojave 10.14.3 (18D109) Since I came back to my parents' house I'm finding a weird thing: When I connect to the Wi-Fi of my house, trying to open whatever type of program on my Mac that requires an internet connection, I see a lag of like 5 or more seconds between the moment I click on the program (for example google chrome) and the moment that the Mac react to my command starting any type of animation showing that it received the command. Also, the speed performances of my internet connection are affected by this thing. If at home I use a VPN (in this case I use Espress VPN), this problem doesn't show up anymore. Plus also outside the house, this thing doesn't happen. So where exactly is the problem? ?
