Embodiment 1

[0112] figure 1 It is an application scene diagram of a Wi-Fi network connection method according to an embodiment of the present invention. Among them, the Wi-Fi device can be used as a station (Station, STA for short) in the uplink direction to access the Wi-Fi network in the 2.4GHz / 5GHz frequency band or other frequency bands; it can be used as an Access Point (Access Point, STA for short) in the downlink direction. AP), that is, a hotspot, so that Wi-Fi terminals in 2.4GHz / 5GHz or other frequency bands can access the Internet through the Wi-Fi device, and can also be used as a terminal with AP functions. Therefore, the specific implementation manner of the Wi-Fi device may be a router, a Mobile Wi-Fi, a data card, etc., or may be a terminal device such as a mobile phone and a PAD with a Wi-Fi function.

[0113] Such as figure 2 As shown, a Wi-Fi network connection method is applied to a Wi-Fi device, and the method includes:

[0114] S1: The first Wi-Fi device acquires...

Embodiment 2

[0178] Figure 9 It is a schematic structural diagram of a Wi-Fi controller according to an embodiment of the present invention.

[0179] An embodiment of the present invention provides a Wi-Fi controller, which is applied to the above-mentioned Wi-Fi network connection method and can be set in a Wi-Fi device. The Wi-Fi controller can at least implement the Wi-Fi in Embodiment 1. Fi network connection method. The Wi-Fi controller includes a Wi-Fi control module 11, which is used to control the Wi-Fi chip to obtain at least one message broadcast by the second Wi-Fi device, each of which contains a channel information; the Wi-Fi control module 11 determines target channel information according to the channel information in the at least one message; the Wi-Fi control module 11 controls the Wi-Fi chip to perform Wi-Fi network access or provide hotspot services for user equipment.

[0180] The Wi-Fi controller provided by the embodiment of the present invention acquires local ch...

Embodiment 3

[0213] Figure 10 The hardware architecture diagram of the Wi-Fi device provided by the embodiment of the present invention.

[0214] The Wi-Fi device 100 in this embodiment is applied to the Wi-Fi network connection method in Embodiment 1, and the Wi-Fi device 100 can at least implement the functions of the Wi-Fi network connection method in Embodiment 1 above.

[0215] The Wi-Fi device 100 includes a baseband chip 101 , a Wi-Fi chip 103 and a radio frequency device 102 , and the baseband chip 101 is connected to the Wi-Fi chip 103 and the radio frequency device 102 through a data bus.

Abstract

The invention discloses a Wi-Fi network connection method and a Wi-Fi device. The Wi-Fi network connection method comprises that a first Wi-Fi device obtains at least one message broadcast by a second Wi-Fi device, wherein each message comprises channel information; the first Wi-Fi device determines target channel information according to the channel information in the at least one message; and the first Wi-Fi device performs Wi-Fi network access or provides hot spot services for a user device according to the target channel information. According to the invention, the first Wi-Fi device determines the target channel information by obtaining the channel information in the message, so according to the target channel information, the first Wi-Fi device is allowed to normally perform Wi-Fi network access or provide hot spot devices.

Description

technical field [0001] The embodiments of the present invention belong to the technical field of communication, and specifically relate to a Wi-Fi network connection method, a Wi-Fi controller, and a Wi-Fi device. Background technique [0002] With the continuous development of wireless high-fidelity (Wireless-Fidelity, Wi-Fi for short) technology, Wi-Fi networks have been more and more widely used. The Wi-Fi channels used and the requirements for Wi-Fi channels in different countries may be different. [0003] When Wi-Fi devices use Wi-Fi networks in various countries, they must meet the Wi-Fi communication requirements of the local countries. With the rapid development of Wi-Fi technology, the communication channels and requirements of various countries are also constantly changing. Therefore, when the preset channel list on the Wi-Fi device is not updated in time, it will be different in different countries according to the set channel list. Local Wi-Fi networks may not...
