Lenovo lenovo thinkpad e450 notebook, Windows 7, the office LAN,

Cable to connect to other notebook can be used but not plugged into my front-end ports, according to "did not identify the network,"

Have tried IP, etc. To automatically access, network card drivers unload heavy for many times, network and local area network (LAN) to ensure that, for how to deal with solution?

CodePudding user response:

1, the device manager and then enable disable the network card, and then manually specify the IP and DNS to see if normal; And cancel in the TCP/IP protocol IPv6 check;

2, if make sure the network card driver is wrong, does not exclude the nic itself the cause of the problem, suggest using PE with network function after startup disk to start the machine to see if can use the network function, no problem, if the network card can explain itself suggest redo system; If it still doesn't work, find the ThinkPad after processing;
