The invention relates to an exception recovery method and an exception recovery device for a device with a network interface card and a memory device. The method comprises the following steps: acquiring identification information of a network interface card device in the accessed device; acquiring state information of the network interface card device according to the identification information of the network interface card device; judging whether the network interface card device is exceptional or not according to the state information of the network interface card device; and unloading a driving program of the network interface card device and re-loading the driving program of the network interface card device if the network interface card device is exceptional. According to the method disclosed by the invention, a technical means for re-unloading the NIC (network interface card) device is adopted, the technical problem that the NIC device can become exceptional when a wireless Internet access data card is pulled out in a forced manner is overcome, and the technical effect of recovering the NIC device to the normal state without re-starting a PC (personal computer) is achieved.
Description
technical field [0001] The present invention relates to the field of wireless communication, in particular to the technical field of network interface cards, and in particular to a method and device for recovering abnormality of a device having a network interface card and a storage device. Background technique [0002] With the development of Internet technology, the traditional wired Internet access method cannot meet the needs of users to access the Internet anytime and anywhere, and users begin to access the Internet through wireless methods. Accessing the network through a wireless data card is a relatively common method of wireless Internet access. In use, the wireless data card can also simulate other device types through the Universal Serial Bus (USB: Universal Serial Bus), such as modem, COM port, A network interface card (NIC: Network Interface Card), CDROM, etc., so that a wireless data card has multiple functions. The multiple devices simulated by the wireless d...
