An old andre's phone, a data lineWireless net cardOr a desktop computer too far from the router。
It doesn't sound so hard, but it turns out there's a place that can get stuck。
First, there must be a data line that transmits data, not the type that can only charge。
This is the first place to be ignored。
Put one end of the line on the phone and the other on the usb mouth of the computer。
Hand-to-hand, let's leave it alone. The default "charging only"。
The computer didn't react at that time because the key settings were in the phone。
The first step is to wake up a hidden menu in the phone。
Turning on the cell phone "set" and going down the way, the probability is that the developer option will not be found。
It needs to be opened manually。
The path is usually "about mobile phones" or "my equipment" in the settings。
Click in and find "all parameters" and you'll see a line called "version number" or "miui version"。
With this line of words, the fingers are attached fast seven times。
On the screen you will jump out a line with a hint that you are in developer mode。
This hidden menu is open。

Now go back to the setup main page, or in "more setup", you can find more of the developer options。
Point in, slide down, find the usb debug。
Open this switch。
Open it to allow more in-depth computer access to mobile phones, which is a prerequisite for sharing networks。
This step is the most critical and the easiest place to believe that the mobile phone is broken。
Also in settings, we found connect and share。
You'll see options like "personal hotspots"。
I'll find the usbNetwork sharingI am not sure。
But this switch is gray. It can't be pressed。
That's the problem。
The design logic of this switch is different from the normal switch。
It's not for you to open it first, then connect to the computer。
Instead, you have to connect your cell phone to the computer with data lines, so this gray switch will light up and become a state of motion。
A lot of people are stuck here because they want to open this switch because they don't connect to the computer, and they find it gray, and they think it doesn't work。
As long as it's connected, the switch will open。
The computer reacts almost immediately。
The network icon in the lower right corner will be disconnected from the state to the connected icon。
The computer used at this time is a network of mobile phones shared through usb。
Cell phones themselves can be linked to wi-fi, or can be used in their own 5g or 4g traffic。
Either way, for a computer, it's a web line。
This connection is more stable than the wireless hotspot on the starter。
The usb direct company delay was measured to be approximately 40 per cent lower than the wi-fi hotspot。
The advantages of such an approach are evident in the use of videoconferencing or in dealing with work that is demanding for the stability of the network。

How sure is not really connected。
