  • First through the computerping 192.168.1.1, check whether the wireless network between the computer and the router is normal. The Ping packet here is normal, which can basically eliminate the problem of the router.

  • After opening these three pages, I found that packet loss occurred in the synchronization of Ping gateway and external address. Then I was asked to connect to the wireless network of another household. After a period of observation, I found that there was no intermittent phenomenon. Then switch back to my network again, and the packet loss is still regular.
  • Then I looked at the adapter box outside the house, unplugged the connection port of the dial-up bus here and replaced it with another port. After observing for some time, I found that the problem had disappeared.
