Abstract

The invention discloses a method for automatic seamless network port switching. The method is used for automatically switching a device into a networking state of a wireless data card when the wireless data card is used. The method comprises the steps of acquiring network port information of a wireless data card and routing information of an IP routing table, and modifying the Metric values of the wireless data card and other network cards in the IP routing table according to the network port information of the wireless data card so as to adjust a default gateway. As the default gateway can be adjusted by adjusting the Metric values of the wireless data card and other network cards so as to enable the default gateway to automatically jump to the IP address of the wireless data card, a data processing device can be automatically switched from a network port of a wireless network card thereof to a network port of a wireless data card without the need for network disconnection and connection operation by users.

Description

technical field [0001] The invention relates to the field of network access of network terminals, in particular to a method for automatically and seamlessly switching network ports. Background technique [0002] At present, in order to realize the wireless Internet access function of data processing devices such as notebook computers, these data processing devices all have their own wireless network cards. However, due to different application scenarios or purposes, the data processing device will also use an external network card device with Internet access function, especially with the development of mobile communication technology, such as mobile data cards, Unicom data cards and other devices with Wi-Fi modules. The application of the wireless data card is more and more popular. [0003] However, since the network port of the built-in wireless network card of the data processing device is set as the default gateway, when the wireless data card is connected to the networ...
