Lenovo laptop wireless network connection red cross

Win7 wireless network connection is successful, but the wireless icon in the lower right corner shows a red cross and is not connected.

The reason why a red cross appears on the wireless network connection of a Lenovo notebook may be that the Win7 UI component cannot correctly receive the status change of the network connection.

Therefore, by reconfiguring the network (deleting the network device and rebuilding it), it can be restored to normal. (Recommended learning: web front-end video tutorial)
