Feeling is the issue of network card, ask the old man is how to troubleshoot,
Known 1. A computer failed to get the IP when open the DHCP, automatically set 169.254 7.0.x.x IP, but using another computer can automatically obtain normal B
2. A manually set the IP can surf the Internet after
3. A DHCP service is to start with, but try to reboot prompt error: access denied 5

Hope that the old man some directions

CodePudding user response:

1, determine the DHCP server is normal,
2, A computer network is normal, for computer B cable testing,
3, check whether A computer to A switch in the middle of the DHCP server is normal,
4. Can use wireshark caught look,
5, uninstall reinstall the nic driver try,

The hope can help you!!!!!!!!!!!!!!

CodePudding user response:

Don't listen to 1/f, hundred of copy, manually set the IP can connect to the Internet would rule out his 2 5-tetrafluorobenzoic, you want to make sure that only the DHCP server is normal, if can relay relay is normal, whether can use static IP ping DHCP,
2: the computer itself problem: if the DHCP service open is normal, the probability of a little bit more (if the DHCP is not you, or routing DHCP basically there is no problem)

CodePudding user response:

See DHCP client - this service have closed, and a recent experience, also can get the IP address of the 169.254, but is unable to DHCP obtained, the result is look down in the middle of the cable head production crystal
Aging skin, redo crystal head or direct replacement cable can solve,
