Preface
When it comes to smart home equipment, the first reaction of a small partner may be a sweeping robot, surveillance camera, air conditioner, speaker, etc. With the development of science and technology, there will be more and more smart devices of this type, and even water heaters and kettles may be connected to the Internet in the future to achieve whole-house intelligence.
In addition to mobile phones and computers, Xiaobai himself also has many devices that can be connected to Wi-Fi: speakers, air conditioners, electrical meters, screen projectors, etc.
In the process of use, some partners' devices often can't connect to Wi-Fi, or they will be disconnected after connecting, and there is no way to solve various reasons for querying.
After Xiaobai's test, the reasons summarized are basically as follows:
The body begins
1. Wi-Fi is a Chinese name
Some friends suddenly found that Wi-Fi can be set to Chinese, and then they thought about setting the Wi-Fi they used to Chinese to show their personality.
These Wi-Fi names are really personal, but they are likely to be so personal that some devices can't be searched at all, or can't connect, or often drop off after connecting.
Xiaobai has encountered several devices that will drop when they connect to Chinese Wi-Fi names, and there will be no search. For example: access control equipment, speakers, air conditioners, etc.
If you want to set the Wi-Fi name as Chinese, you may have to pay attention: after setting the Chinese Wi-Fi name, all devices can be used normally, but if there is a drop, etc., you must first consider whether the Wi-Fi cannot be used normally because of the Chinese name.
Second, the router has enabled dual-band integration
Some time ago, many friends reported that after the router turned on the dual-band integration, some devices could not connect normally.
What is Wi-Fi Dual-Band in One?
It refers to the merging of the wireless networks of the router's 2.4GHz and 5GHz frequency bands into a unified wireless network name (SSID), so that the user device can automatically select the frequency band with a strong signal when connecting.
Baidu Encyclopedia
Most routers on the market basically have the dual-band function turned on by default, but there are many smart home devices that only support connecting to Wi-Fi in the 2.4GHz frequency band.
If you find that your smart home device can't connect to Wi-Fi properly, then try turning off the Wi-Fi dual-band function and then connecting your smart home device to Wi-Fi in the 2.4GHz band, which can solve this problem.
- How do I turn off Wi-Fi on my router?
Some friends will be entangled after turning off the dual-band integration: in the past, the mobile phone automatically switched between the 2.4GHz and 5GHz frequency bands of Wi-Fi, wouldn't it be very troublesome after turning it off?
That's what you didn't notice, after turning off the dual-band integration, the computer and mobile phone are directly connected to 5GHz.

What devices are connected to the 2.4GHz band?
It is recommended that other devices (such as air conditioners, smart sockets, speakers, and sweeping robots) be connected to 2.4GHz, except for computers, mobile phones, and tablets that require high network speed.
