The switch is set up to share the Internet, and everyone else can get on it, so why can t one person

Sharing on the same LAN cannot be done because the settings are incorrect.

Steps: 1. Connect both computers to the same router.

2. Right-click on the desktop network --- properties --- change the advanced sharing settings.

3. Select Public Network --- select the following options: Enable Network Discovery--- Start File and Printer Sharing--- Enable Sharing So that users who can access the network can read and write files in public folders (can not be selected) - Turn off password protection sharing (other options use the default).

4. Save and confirm.

5. Select the folder or drive letter that needs to be shared, and right-click - Properties.

6. Open the Security tab - select - Add - everyone.

7. Open the Share tab--- select Share --- pop-up dialog box --- add "guest"--sharing.

8. Select Advanced Sharing --Select Share this file --OK.

9. Select Advanced Sharing -- Select Share this file -- Select Permissions -- Add Everyone.

10. Double-click on another computer to open the network, and the folder or drive letter you just shared will appear.

Note: To prevent accidental errors, turn off the firewalls on both computers.

There is no doubt that there is a problem with the cable connecting the switch and the router or the switch and router interface are not compatible, try to change the interface.

It has nothing to do with routing, you are talking about LAN connection, that does not need to go through the router, you can access each other by plugging in the LAN port of the router, which is equivalent to connecting to a small switch, indicating that the computer configuration is no problem, but it is not possible to connect to the switch alone, indicating that your switch has a problem, if it is a network management switch, see if the switch is set up with VLAN or port isolation functions.

If the switch is a fool switch, you pay attention to whether the line on the switch has a loop, this should be checked, remove the lines of other computers, on these two experiments, if you repeatedly change the port position on the switch, it means that your switch is broken.

It's not that evil, I think you may have a low-level mistake, check it carefully.

I suspect that your switch and router don't work at all. To test it out.

The functional image of the switch is understood as a single interface to multiple interfaces, eliminating the connection problem of N network cables to one network cable.

However, if you need one network cable to connect multiple computers to the Internet at the same time through the switch, the switch alone cannot be completed, because the switch is not smart enough to distinguish which of the multiple computers connected to the transfer machine needs traffic at the same time.

This is where a router is needed, and the router is like a computer that distributes data, which is very smart (its functions include the functions of a switch).

Description of your situation: Situation 1: There is not enough IP at the end of the resource network cable for the computer at the bottom of the switch to allocate (there is no router or the settings are incorrect).

Situation 2: The IP address of your computer and the IP address of someone else's computer are both fixed addresses and conflict with each other.

Situation 3: The switch is damaged.

Set the router to the automatic IP

You can't connect to the intranet, which means you can't ping your friend's computer. It's definitely an issue with the IP. You check the IP.,Is it not possible to get it?,If it doesn't work.,Just add it.。
