Brief description of the problem:
The computer is connected to wifi (public network and) but cannot access the Internet, and even the campus network cannot pop up the authentication interface in the browser, but QQ and WeChat can log in normally.
guess:
- Yesterday, I configured content related to Alibaba Cloud, installed tools such as shell, and performed a series of configurations, which may have affected the proxy server in the process.
- Actual reason: Force restarting the computer when dev-sidecar is turned on, which will cause problems with the agent when the software is running.
Solution
- I also found relevant articles on the Internet, which are basically about modifying the automatic acquisition of ip address, but the problem cannot be solved.
- After consulting the relevant personnel, the problem of modifying the network proxy related settings was solved
step
1. Click wifi in the lower right corner to open the network settings
2. Enable proxy settings and turn off the [Use proxy server] option
