Don't throw the old phone. Just a data line, a second computer, a wireless card

Internet access is a problem when there is a desktop without a wire, or when the home wi-fi signal just doesn't reach the corner of the library。

A lot of people would like to buy oneWireless net cardI don't know。

Actually, the empty andre on the tableOld phoneIf you connect a data line, you can fix it。

The first step in this is to find a usb line with data。

This line is the key。

Many of the wires on the market can only be charged, and the computer is not responding because there are several copper wires missing for data transmission。

With wires that can only be charged, the next steps cannot be followed。

So, it has to be the original cell phone, or the type of line clearly written on the packaging that supports data transmission。

One of the wires was inserted on the phone and the other was suggested to be inserted directly on the main board of the desktop。

The u. S. B. Mouths in front of the aircraft boxes, sometimes with unstable power supply, may lead to a breakdown of the connection。

When it's plugged in, the phone screen will light up and the tip is charging。

Leave it alone。

Pick up the phone, and then the real setup。

To make a cybercard for a computer, you have to turn on a device that's hidden in a cell phone。

This function is called developer options。

This option is invisible when most mobile phones leave the factory。

It takes a specific move to get it out。

Open the cell phone's settings。

Slip to the bottom and find "about the phone."。

Click in and find a version number or an entry like miui。

That's the line that shows the version of the phone system。

On this line, you hit it fast seven times with your finger。

Don't slow down, not a few。

When you click to the bottom of the screen, you usually pop a line of small words suggesting " you have an x-step to enter the developer mode " 。

Until screen tip " you are now in developer mode."。

This hidden menu is open。

This operation is allAndre's phoneIt's almost all right, except that the version number may be slightly different in different branded mobile phones。

Now back to settings main interface。

Re-read it, or flip it in "systems", "more settings."。

One more "developer option" will be found。

Point in。

We need to open one in hereUsb debugIt's the switch。

Find it, open it。

The cell phone could pop up a warning to you about the usefulness and risks of usb debugging。

Just make sure it's open。

The function of this switch is to allow computers to send more complex instructions to mobile phones via usb lines, not just to transmit files。

Following this step, the mobile phone's preparation is half complete。

Now, we can turn our attention back to the connection itself。

In the "setting" of mobile phones, you can find the "network and internet" or similar "connect and share" menu。

You'll see the "personal hotspot" option。

We usually use our cell phones to use the wi-fi hotspot for other devices online, which is where it's set up。

But not this time。

In addition to the wlan hotspot, there is an option for usb network sharing on the personal hotspots set-up page。

For the first time, this "usb sharing" switch is mostly gray。

I can't light, i can't open。

This is the easiest place for people to give up。

It's like a cell phone or a computer doesn't support it。

In fact, the switch is grey because the prerequisites for its entry into force have not been met。

It needs a cell phone to connect to the computer with data lines and to open the usb debugging。

Now, since we've done this before, the switch should be lit。

Open it。

In an instant the cell phone was turned from a simple charger to a network device。

In the device manager for windows computers, it is recognized as a remote network drive called rndis。

It's a standard agreement, and the systems after windows 7 are basically self-propelled。

If the drive is normal, the network icon at the bottom right of the computer will react immediately。

An icon displays a cable connection。

This means that computers are online via mobile phones。
