1, please confirm whether there is IP conflict in the local area network, resulting in network restriction. I suggest you try to specify the IP address manually.
2. By inserting a network cable in other network environments, the notebook computer is tested separately.
3. Uninstall the network card driver, and then download and install it from official website (in Control Panel-Programs and Functions-uninstall the LAN driver network card driver first, and then install it).
The download link of the 64-bit version of the network card driver is:/notebooks _ ultrabooks/x550dp/helpdesk _ download/
(After opening this page, click "Drive &; Tool software "-select OS, select system version-network driver).
4. In terms of system, it is recommended that you use the pure version of windows to ensure driver compatibility.
