A conexão de rede degrada depois de um tempo

0

Minha topologia é a seguinte:

Fiber -> Modem --[PPPoE]--> WiFi Router --[Cable]--> Win Computer A
                                  |
                                  '-------[Cable]--> Mac Computer B

O meu router WiFi é um RT-AC66R e tem o firmware oficial mais recente. Eu mudei os cabos de rede e as portas do roteador durante a depuração desse problema, mas nada mudou.

Os IPs são 192.168.1.217 (A) e 192.168.1.164 (B).

Logo depois que eu ligo o computador Windows, os tempos de ping do computador Mac estão dentro de alguns milissegundos. Depois de um tempo, começa a degradar:

64 bytes from 192.168.1.217: icmp_seq=1277 ttl=128 time=4617.294 ms
64 bytes from 192.168.1.217: icmp_seq=1278 ttl=128 time=3614.986 ms
64 bytes from 192.168.1.217: icmp_seq=1279 ttl=128 time=8025.265 ms
64 bytes from 192.168.1.217: icmp_seq=1280 ttl=128 time=8024.973 ms
^C
--- 192.168.1.217 ping statistics ---
1289 packets transmitted, 1021 packets received, 20.8% packet loss
round-trip min/avg/max/stddev = 0.313/4254.498/9027.763/2814.197 ms

Quando finalmente recebo 100% de perda de pacotes:

mbp13:~ $ ping 192.168.1.217
PING 192.168.1.217 (192.168.1.217): 56 data bytes
Request timeout for icmp_seq 0
Request timeout for icmp_seq 1
Request timeout for icmp_seq 2
Request timeout for icmp_seq 3
^C
--- 192.168.1.217 ping statistics ---
5 packets transmitted, 0 packets received, 100.0% packet loss

E o mesmo acontece com o computador B para o A:

C:\Windows\System32>ping 192.168.1.164

Pinging 192.168.1.164 with 32 bytes of data:
Reply from 192.168.1.217: Destination host unreachable.
Reply from 192.168.1.217: Destination host unreachable.
Reply from 192.168.1.217: Destination host unreachable.
Reply from 192.168.1.217: Destination host unreachable.

Ping statistics for 192.168.1.164:
    Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),

Uma coisa que acho que contribui para esse problema é que estou usando um programa VPN no computador Windows da AT & T. Aqui está a lista completa de interfaces de rede para o computador Windows:
