He encontrado enrutadores WiFi donde no puedo abrir dominios, pero las direcciones IP de ping son correctas Esto significa que no puedo navegar por sitios web. Esto sucede solo en mi Macbook y estas conexiones funcionan bien para las computadoras portátiles con Windows. ¿Cómo soluciono esto?
Tengo dos AP de Internet en mi oficina, una es problemática, una no lo es. También tengo un wifi en casa que funciona, pero otro wifi en la casa de mi amigo no funciona.
Detalles
Estas pruebas se realizaron en la misma máquina. Puedo cambiar a WiFi y esto siempre sucede.
