IP address dynamic allocation method and device, memory medium and wireless repeater

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...

Problems solved by technology

[0004] However, with the widespread use of wireless relay devices, users have higher and higher requirements for the ease of use of wireless relay devices, and the manual configuration method provided by the prior art increases the difficulty for users to use wireless relay devices; in addition, the above The method of manually configuring the DHCP server requires the user to have certain basic knowledge of network configuration, otherwise the network may be abnormal due to configuration errors. For example, when there is a DHCP server in the LAN and the user starts the DHCP server of the wireless relay device, It will cause abnormal acquisition of IP addresses of other devices in the network and affect communication; when there is no DHCP server in the LAN and the user turns off the DHCP server of the wireless relay device, other devices in the network will not be able to obtain IP addresses and cannot communicate
