检查路由器设置(Check Router Settings)
如果您最近更换了路由器，您可能需要重新配置计算机和打印机以重新连接网络。
新路由器可能有不同的ISP地址，需要重新配置和调整路由器设置，其中一些可能不适合您的无线打印机。
- 要检查路由器设置，请打开浏览器并输入其 IP 地址，然后按Enter。如果您不确定 IP 地址，请阅读我们的帖子如何查找路由(find the IP address of a route)r 的 IP 地址。可以尝试使用admin作为用户名，password作为密码，这是路由器常用的默认密码(default passwords for routers)。
- 找到无线(Wireless)或安全(Security)部分并将设置调整为默认设置，以便打印机连接。
您可以在路由器设置中检查的一些事项包括：
- MAC 地址过滤(MAC address filtering)- 禁用它，因为它确实不会使您的网络安全。
- 检查您的路由器是否处于 2.4GHz 频段，与仅连接到 5GHz 模式相比，大多数无线打印机都可以轻松连接到该频段。
- 使用其他本地网络最少使用的WiFi 频道(WiFi channel)。对于未连接的打印机，通道 1、6 和 11 通常效果最好，而不是默认的“自动”通道选择设置。
- 禁用无线隔离模式设置并尝试再次连接到打印机。
- 启用DCHP以允许您的打印机获取 IP 地址并通过网络进行通信，并尝试重新连接。
- 检查您的路由器、设备或打印机是否有访客连接，因为这会将它们与网络上的其他设备隔离，并阻止您的无线打印机连接。
更新路由器固件(Update Router Firmware)
如果更改路由器设置没有帮助，请更新其固件以解决错误或漏洞和连接问题。
例如，从不同版本迁移到Windows 10可能会导致连接中断，固件更新可以解决此问题。
请查看您的路由器手册或咨询设备制造商以获取更多说明，因为步骤可能因不同路由器而异。有些可能还需要特殊说明才能连接到无线设备，尤其是ISP(ISPs)提供的那些。
禁用 VPN 连接(Disable VPN Connections)
如果您使用虚拟专用网络(virtual private network)安全地连接到远程网络，它可能会限制您通过WiFi打印机进行打印。出于安全原因会发生这种情况，但您可以禁用VPN连接并尝试连接到家庭网络并恢复打印功能。
将打印机 IP 地址设为静态(Make The Printer IP Address Static)
无论您的设备是否保持在同一位置，IP 地址都可能在特定范围内波动。这可能会令人困惑，尤其是在多个设备尝试在给定持续时间内进行无线连接的情况下。
在这种情况下，请查看路由器手册以获取有关如何为打印机设置静态 IP 地址以使其不会随时间变化的说明。
检查防火墙设置(Check Firewall Settings)
您设备的防火墙旨在阻止来自恶意软件的任何攻击(attacks from malware)，但它也可以阻止网络设置进行打印。根据设备的配置方式，它可能会过度保护您的设备，并且不会让它通过本地网络看到您的打印机。
防火墙(Firewall)设置有所不同，在这种情况下，您应该查看用户指南或供应商网站以获取支持资源。
确保(Make)您的软件保持最新，将防火墙设置设置为中等或您的设备连接到网络的“受信任区域”，并使其(enable it)显示所有警报消息。
检查您是否没有同时启用多个防火墙，因为这会导致多个无线打印机连接问题，或者您可能会发现您的无线打印机无法打印。
更改您的 SSID(Change Your SSID)
更改 WiFi 网络的名称(Changing the name of your WiFi network)( SSID ) 可能会解决连接问题。如果有多个具有类似SSID的路由器（例如Home），您可以更改其中一个以使其可被您的打印机识别，并解决由于连接中断或无线连接不正确而导致的连接错误。
这样做意味着您必须将计算机系统或兼容设备重新连接到打印机所连接的正确网络。

How to Troubleshoot WiFi (Wireless) Printers
Few things аre morе frustrating than when you want to print a documеnt, and уour wirеless printеr is in an error state, or gives уou the silent treatment. Perhaps you’ve tried to сonnect your WiFi printer to the network in your home, but thе рroblems persist, lеaving your printer stυbbornly off the grid.
Ideally, a wireless connection should allow you to transfer documents easily from your device to the printer, but it’s not always that simple in reality.
Knowing how to troubleshoot wireless printer issues can relieve some of that frustration. We’re going to cover some fixes that’ll help you work through most of them below.
Troubleshoot Wireless Printer Problems
- Check the basics.
- Set your printer as the default printer.
- Restart all your devices.
- Run the Printing Troubleshooter.
- Check Router settings.
- Update router firmware.
- Disable VPN connections.
- Make printer IP address static.
- Check Firewall Settings.
- Change your SSID.
- Uninstall and reinstall printer driver and software.
- Uninstall and reinstall the printer.
- Clear and reset print spooler.
- Reset your printer.
Check The Basics
It’s possible to overlook some basics so here’s what to check for before moving to advanced steps:
- Make sure the printer is on or that it has power.
- Connect your printer to your computer or other device
- Check the printer’s toner and paper, plus the printer queue. Sometimes a print job with an error may hold up the line, the travel time for files from your device to the printer may take more time, or a larger document may take longer to download and process.
- Check for any warning lights or error messages on the printer.
- Make sure it’s connected to WiFi.
- Use a USB cable to connect and see if it works again.
- Move your printer to where it gets the best WiFi signal without interference. Ideally, it shouldn’t be too far from the router.
- Confirm that your device is also on the right network especially where there’s a WiFi range extender as this creates separate networks, making it harder to connect.
- If you recently updated your browser, security software, operating system or firewalls, it could cause issues connecting to your printer. In this case, reconnect your device to the network, reconfigure security settings to include printers, and/or install updated drivers.
You can also perform a System Restore to go back to the default version or settings and try connecting to your printer again.
Set Your Printer As The Default Printer
It’s possible that you’re trying to connect to a WiFi printer that has set itself as the default. Sometimes a printer may install software that has a “virtual” printer so that when you hit the Print command, the virtual printer saves the file instead of the actual document you’re sending to the physical printer.
1. Click Start > Control Panel > Hardware and Sound.
2. Click Devices and Printers.
3. Right-click your printer and select Set as default printer. Click Yes (or OK) to confirm the action.
Restart All Your Devices
A restart helps fix any software glitches that could cause your wireless printer and connected devices not to work properly together. The wireless printer, router, computer/other device, wireless access point and modem all rely on your home or office network in order to connect to the internet.
However it’s configured, if one device acts up, it may affect all the others. A restart can get the network humming again, after which you can try the printer to see if it works.
Run The Printing Troubleshooter
1. To do this, open Control Panel > Hardware and Sound > Devices and Printers.
2. Right click the printer icon and click Troubleshoot. The printing troubleshooter to identify and fix problems connecting to your printer.
3. Alternatively, go to the search box on the taskbar and type Printing problem in, and then select Run Troubleshooter to download the printing troubleshooter. Click Open and follow the on-screen instructions.
Check Router Settings
If you replaced your router recently, you may have to reconfigure the computer and printer to reconnect with your network.
The new router may have a different ISP address that needs reconfiguration, and adjustment of router settings, some of which may be unsuitable for your wireless printer.
- To check router settings, open your browser and type its IP address and press Enter. If you’re not sure of the IP address, read our post how to find the IP address of a router. You can try using admin as the username, and password as the password, which are the commonly used default passwords for routers.
- Find the Wireless or Security section and adjust the settings to default for the printer to connect.
A few things you can check in the router settings include:
- MAC address filtering – disable it as it really doesn’t make your network secure.
- Check if your router is in the 2.4GHz frequency band, which most wireless printers easily connect to compared to connecting to the 5GHz only mode.
- Use a WiFi channel that’s least used by other local networks. For printers that aren’t connecting, channels 1, 6, and 11 usually work best, instead of the default “Auto” channel selection setting.
- Disable wireless isolation mode setting and try connecting to the printer again.
- Enable DCHP to allow your printer to acquire an IP address and communicate over the network, and attempt reconnection.
- Check that your router, device or printer has a guest connection, as this isolates them from other devices on a network, and prevents your wireless printer from connecting.
Update Router Firmware
If changing the router settings didn’t help, update its firmware to address bugs or vulnerabilities and connectivity issues.
For example, moving to Windows 10 from a different version could create an interruption to your connection, which a firmware update could solve.
Check your router’s manual or consult the device manufacturer for further instructions as the steps may vary with different routers. Some may also require special instructions to connect to wireless devices, especially those provided by ISPs.
Disable VPN Connections
If you’re using a virtual private network to connect securely to a remote network, it could restrict you from printing through your WiFi printer. This happens for security reasons, but you can disable the VPN connection and try to connect to the home network and resume printing functions.
Make The Printer IP Address Static
IP addresses can fluctuate in a particular range, whether or not your device remains in the same spot. This can be confusing especially where several devices are attempting to connect wirelessly over a given duration.
In this case, check your router’s manual for instructions on how to set a static IP address for your printer so that it won’t change with time.
Check Firewall Settings
Your device’s firewall is designed to block any attacks from malware, but it could also block network settings for printing. It could be overprotective of your device depending on how it’s configured, and won’t let it see your printer over the local network.
Firewall settings vary though, in which case you should check the user guide or vendor’s website for support resources.
Make sure you keep your software up-to-date, set firewall settings to medium or “Trusted Zone” where your device is connected to a network, and enable it to show all alert messages.
Check that you don’t have multiple firewalls enabled at once as this causes several wireless printer connection issues or you may find your wireless printer not printing.
Change Your SSID
Changing the name of your WiFi network (SSID) may solve connectivity issues. If there are multiple routers with a similar SSID like Home, you can change one of them to make it recognizable by your printer and resolve connectivity errors due to drops in connection or incorrect wireless connection.
Doing this means you have to reconnect a computer system or compatible devices to the right network that the printer is connected to.
Uninstall & Reinstall Printer Driver & Software
This involves reinstalling or reconfiguring your printer’s special network drivers.
1. Open Control Panel > Programs.
2. Click Programs and Features > Uninstall a program.
3. Click your printer’s name and then click Yes to confirm the action. Turn on the printer and go to the manufacturer’s site to get specific instructions for downloading and installing the drivers for your model. Once installed, follow the steps to set up the printer connection and try printing again.
You can also reinstall printer drivers using Windows Update, by clicking Start > Settings > Update & Security and click Check for updates. If an updated driver is available, it will download and install and your printer will use it.
Alternatively, use the disc installation software that came with your printer as this may help you install its drivers or check for driver updates.
What If The Printer Driver Doesn’t Install?
1. In this case, click Start > Settings > Devices.
2. Click Printers and Scanners and then click Print server properties under Related settings.
3. Go to the Drivers tab and check for your printer. If it’s there, you’re good to go. If not, click Add.
4. Click Next in the Welcome to the Add Printer Driver wizard
5. Click on your device’s architecture in the Process Selection box, and click Next.
6. Under Printer Driver Selection, click your manufacturer, select the printer driver, and then click Next > Finish. Follow the on-screen steps to add your printer’s driver.
Note: If no new drivers are available, contact the manufacturer and ask when they’ll be available. If your printer model is no longer supported, you can check with a printer in the same series for updated drivers as there’s a likelihood they’ll work for yours, with some loss of functionality though.
It’s a long shot, but there’s not much to lose if it’s not working already.
Uninstall & Reinstall The Printer
Try to remove your printer and reinstall it to see if the connection will work for it to print again.
1. To remove the printer, click Start > Settings > Devices. Click Printers and Scanners and find your printer, click on it and select Remove device.
2. Reinstall the printer by clicking Start > Settings > Devices > Printers and Scanners. Select Add a printer or scanner.
3. Choose your printer from the list of available ones (including Bluetooth or printers connected to another computer and shared on your network) and click Add device.
Note: If you use an extender, wireless access points, or multiple routers with different SSIDs, ensure you’re connected to the same network so your device can find and install your printer. Print a test page to be sure it works properly.
Clear & Reset Print Spooler
The print spooler manages the printing process. If you find your wireless printer not printing, the print spooler could have a problem. In this case, clear the spooler files and restart the spooler service.
1. In the search box, type services and choose Services from the search results.
2. Click Standard tab and double-click Print spooler.
3. Click Stop > OK.
4. Type %WINDIR%\system32\spool\printers in the search box again, and then select %WINDIR%\system32\spool\PRINTERS from the search results. Delete all the files in that folder.
5. Type services and select Services. Click Standards tab, and double-click Print Spooler from the list. Click Start and in the Startup type box, select Automatic and click OK.
Reset Your Printer
This is a last resort solution when all other fixes have failed because it clears all your printer settings, including the WiFi login credentials in order to reestablish a connection.
Check your printer manual for directions on how to perform a factory reset as the steps vary by brand and model. The information may also be available online if you don’t have an owner’s manual.
We’ve covered most probable fixes to wireless printer problems, if yours still won’t connect after going through each of these fixes, you can consult the manufacturer, return it to the store, or buy a new printer and start over.
