Why is my home wifi network NOT working intermittently?

My home wifi broke intermittently, how can I troubleshoot it?

Background

I use China Telecom service, they provide a smart SDN gateway, which is fiber 1000 M speed. The wired network is working smoothly all the time.

The issue occurs with the wifi, it brokes intermittently. When it broke, the wifi connection status shows normally, but no internet access. The DNS time-outs.

What I tried

  • I tried all the well-known DNSs, for example, 8.8.8.8, 114.114.114.114, etc. No effect.

  • I bought another dual frequency and dual 1000 M wifi router, same issue.

  • I tried locking the signal channel, but no effect. Same issue.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
