He encontrado los routers WiFi donde no puedo abrir los dominios, pero ping a las direcciones IP bien. Esto significa que no puede navegar por los sitios web. Esto solo pasa en mi Macbook, y estas conexiones funcionan muy bien para Windows portátiles. ¿Cómo puedo solucionar este problema?
Tengo dos internet AP en mi oficina, uno es problemático, no. También tengo una wifi en casa que funciona, pero otra wifi en casa de mi amiga no funciona.
Detalles
Estas pruebas se realizaron en la misma máquina. Puedo cambiar a WiFi y esto siempre sucede.
Los Routers que están muy bien:
