Abstract

The invention discloses an IP address dynamic allocation method. The method is performed by each wireless repeater in a local area network. The method comprises the steps of detecting whether the wireless repeater is connected with a front end wireless AP or not; starting a DHCP server of the wireless repeater when the wireless repeater is not connected with the front end wireless AP, thereby providing IP address dynamic allocation service; detecting whether the DHCP server exists in the local area network or not when the wireless repeater is connected with the front end wireless AP, thereby providing IP address dynamic allocation service; starting the DHCP server of the wireless repeater if the DHCP server does not exist, thereby providing the IP address dynamic allocation service; and shutting down the DHCP server of the wireless repeater if the DHCP server exists, and obtaining a corresponding IP address from the DHCP server existing in the local area network. Correspondingly, the invention discloses an IP address dynamic allocation device, a memory medium and the wireless repeater. Through adoption of the technical scheme provided by the invention, the usability of the wirelessrepeater can be improved, and network anomalies due to error configuration of a user are effectively reduced.

Description

technical field

[0001] The invention relates to the technical field of wireless networks, in particular to a method and device for dynamically assigning an IP address, a computer storage medium, and a wireless relay device. Background technique

[0002] Wireless repeater (Repeater) is a wireless device used for wireless signal extension. It can not only receive the signal of the front-end wireless AP, but also serve as a wireless AP to provide a wireless network to the back-end devices connected to it to realize the function of wireless repeater. If the front-end wireless AP, wireless relay device, and back-end device are in the same local area network, this involves the problem of dynamic allocation of IP addresses of the devices in the local area network. In most cases, the front-end wireless AP will open its own DHCP server (a server for dynamically assigning IP addresses) to assign IP addresses to devices connected to it, and the wireless relay device will not connect to...
