You can t connect to printer 10 with a switch

Look at your problem, your computer and your printer are definitely not in the same network segment, for example, your computer is, your printer is, then no, because the IP of the printer is dead, so the address set by the router should follow the IP of the printer.

Then you have to set the IP of the router is.

You have to change the IP of your machine.

If you can't read it, send your printer IP out and take a look.

Disconnect the route and try to go to the switch alone, if you can ping each other, then sharing is absolutely fine, if you can ping but can't share, there must be a problem with the computer settings. If the single-pass switch cannot be pinged, check the settings of the firewall, switch, and NIC settings.

What brand and model of printer do you have?

Directly use the printer to type a configuration page, see if the IP of the printer and the computer are in the same network segment, and whether the computer can ping the IP of the same printer

Is the printer a network printer? Does the printer set the IP automatically or assign it manually?

When connected to the switch, can the computer ping the switch IP be able to ping?

The IP is set by the engineer and cannot be modified.

Set it up inside the wireless router.

Method 1: 1. Change your computer's IP address to, and then connect the computer to the LAN port of the router with a network cable.

2. Log in to the router: The initial account password is on the back of the router).

3. Change the Internet item of the router to a fixed IP, and enter the IP, mask, gateway and DNS given to you by the school

4. Set the LAN of the route (can be unchanged).

5. Set the wireless LAN of routing, such as SSID, password, etc.

6. If your wireless LAN needs to automatically obtain the IP, turn on DHCP, otherwise it will not be turned on.

Method 2: You can use the wireless router as a wireless AP, and the setup steps are as follows:

1. Connect and log in to the wireless router on a stand-alone machine, change the IP address of the LAN port of the wireless router to avoid conflicts with other devices on the intranet; Turn off the DHCP function of the wireless router and restart it;

2. Connect the 1 2 3 4 ports of the wireless router with the router in the wired network (in fact, the switch can also be used) wired;

3. Connect the wireless network card in the operation network to the wireless router;

4. Configure the network parameters of the wireless network card (automatically obtained or manually configured, and the manual configuration parameters are consistent with the wired);

Double-click on the computer connected to the printer in the online neighborhood, and if you don't have permissions, log in as a senior administrator user. Be sure to set a password on the computer that is connected to the printer. After logging in, double-click the shared printer and click Yes.

Is it that the IP segment you are in after connecting to the wireless router has changed?

After you use the router, your laptop and printer are no longer in the same LAN, that is, cross-gateway, so you can't share print!

If your wireless router can be set up as a wireless AP as said on the 2nd floor, then the problem is solved!

Then you can connect the wireless router to the switch where the printer is located, but this method is probably not suitable for your problem, or you won't ask this question!

How to use a wireless connection switch for printers:

1. Test the LAN intranet IP of the PC where the printer is installed; Start button in the bottom left corner -- run -- enter cmd enter -- enter ipconfig all in the window that opens.

2. Intranet IP and gateway information appears.

3. Here: the internal IP of the printer's PC

4. Check the intranet IP of the LAN on the PC with wireless connection;

5. Please check whether the gateway address is different from the gateway address of the printer PC.

6. The intranet IP of the PC with wireless Internet access

8. Select the option to connect to the printer, enter the IP address of the printer PC in the name When you enter the last one, the printer name under this IP address will be prompted below, and then click to fill in the finish.

9. The next step prompts, continue to confirm.

10. You need to ensure that the printer of the printer PC is shared, if not, in the lower left corner of the printer PC - Start - Control Panel - Printer and Fax - Right-click the --- properties of the printer you want to share - Share - Share this printer - OK.

11. Follow the wizard to continue to determine or next until completion.

12. Finally, go to the printer page to view the installed network printer: lower left corner - start - control panel - printer and fax to enter the printer page.

13. Finish setting up the printer and connect it to the switch.

Direct connection requires this printer to have a network function, and you can simply judge whether the printer has a network port plugged in the network cable.

If not, the easy solution is to buy a dedicated web print server. It's usually small, and I use it the size of a pack of cigarettes.

When buying, make sure that your printer is in one of the supported models.

Buy a network printer, power it up, and then lead the network cable from the switch, then call the customer service to set a static IP and then install the driver OK on the local computer

You can add a network print server.

Unplugging the hub and connecting directly to the computer is normal, which proves that the connection between the school side and the school router is normal.

If the switch is also slow, it means that the problem is not in the hub or switch, it is likely that other people are also sharing the bandwidth on the Internet; If other people surf the Internet just to chat, operations such as browsing the web generally do not have a great impact on the Internet speed; If other people**movies, other relatively large files or **browsing**, it will have a great impact on the Internet speed; If there is no one **, it is also possible that someone's computer has a virus and keeps accessing the Internet; If the cause of the poisoning is ruled out, it is also possible that someone has installed a similar network firewall to restrict others from surfing the Internet (in this case, it is estimated that you have someone who is more familiar with computers, not necessarily a master).

Of course, there are other reasons that need to be determined on a case-by-case basis.

See which cable is the problem, plug it in one by one, pull it out one by one to see which cable or which computer is connected to get stuck. I found him and kicked him directly....

Hello, because you are splitting the line from the route, so, there must be multiple IPs to use multiple computers to access the Internet, so, so here, you did not explain, so it feels like you are being limited in speed,

You can connect like this, but make sure that the printer and the computer are on the same network segment.

At the physical layer, it should be noted that there is a difference between a straight line and a cross line. If the peer side is also a switch and the local end is a switch, then a crossover wire should be used. If the peer is a switch and the parent is a computer, then a pass-through cable should be used.

The new switches now have an automatic flip function, which can be used with any cable. But the old switch didn't have it. Therefore, if it is an old model, pay attention to the problem of the line.

If there is no problem at the physical layer, then the problem at the link layer should be noted.

It may be caused by a mismatch between duplex and rate. Try specifying the same duplex or rate manually.

It may be a speed problem with the computer network card, and the solution is the same as above.

It is possible that the upstream device is bound to the IP and MAC.

It is possible that the upstream device limits the number of Macs (i.e., computers or devices) that can only pass through a network port, and it may be 1-5.

There is a difference in what cable you are.

1. First connect the network cable from the neighbor's router to connect a computer separately to whether it can access the Internet, first put this network cable (call it the source of the Bird bus) no problem.

2. Second, do you confirm that you are connected to the Recco switch (don't be upset, some people can't tell the router switch).

3. If the above two items are confirmed. Connect the bus to port 1 of the switch (of course, you can connect several ports), and then connect the computer to port 2 and 3 respectively. Well, it's better to use automatic acquisition, of course, provided that your neighbor's router has turned on the DHCP function.

If you have to set a fixed IP, remember that the Hail Spike is set to a network segment with the router LAN port IP, the default gateway, and the DNS must be set to the right (I think since you will set a fixed IP, these should understand).

4. If you can't access the Internet, it depends on whether the switch is broken.
