My internet is intermittently slow/unavailable on the my MacBook Pro.
My internet is intermittently slow and frequently unavailable on the my MacBook Pro .(OS Mojave 10.14.5), but it's fine on all my other devices (iPhones, other MacBooks). I've had my modem/router replaced, and the other MacBooks connect fine anyway. Help!
MacBook Pro 13", macOS 10.14
