Llevo unos días que al listar servidores, un grupo de ellos tan pronto aparece online como offline. Hoy también he notado la navegación lenta y/o que se atasca. El caso es que he querido hacer un ping a un servidor (100 paquetes) y éstos son los resultados:

PING 91.198.152.197 (91.198.152.197) 56(84) bytes of data.

Falsa alarma... he obligado a resincronizar el router para tener un SNR de 9dB sobre fastpath, que había bajado por debajo de 7dB. Adiós a la perdida de paquetes.

Gracias.
