On the internet, we often encounter such, such a network failure, how to deal with it?
Today, we have a few common problems for you to analyze!
1. Symptom: Network adapter (NIC) settings conflict with computer resources.
Analysis, exclusion: Avoid conflicts with other resources of the computer by adjusting the IRQ and I/O values in the network card resource. In some cases, it is also necessary to adjust the conflict with other resources by setting the motherboard jumpers.
