Modern laser MFP series HP Laser 135wr Wireless network adapters have become a popular choice for small offices and home offices due to their compact size and functionality. However, initial setup of a wireless connection often presents difficulties for users accustomed to wired interfaces. Proper network configuration allows you to print documents from a laptop, smartphone, or tablet without having to reconnect a cable each time.
In this guide, we'll cover all available methods for connecting your device to a router. You'll learn how to use automatic setup via WPS, pair via USB to transfer network settings, and manage printing via a mobile app. Connection stability directly depends on the correctness of the actions performed at the initial stage.
Before you begin, make sure your MFP is turned on, the cartridges are installed, and your router is working properly. You will also need to know your Wi-Fi network name (SSID) and password. If you plan to use static IP address, reserve it in the router settings in advance to avoid addressing conflicts in the local network.
Preparing equipment and checking indicators
The first step before starting setup is to visually diagnose the device's status. Look at the control panel of your HP Laser 135wrThe wireless network indicator should be blinking blue, indicating that the device is waiting for a connection. If the indicator is solid, the device is already connected to a network and may need to be reset.
To reset network settings to factory defaults, press and hold the wireless button on the control panel for a few seconds. This typically takes 5-7 seconds, until the lights begin flashing in a specific pattern. This clears saved network profiles, which is critical if you change your router or Wi-Fi password.
⚠️ Note: Resetting your network settings will delete all previously saved connection settings. Make sure you have the current password for your Wi-Fi network handy, as you will need to re-enter it.
Make sure your computer or smartphone used for setup is within the same Wi-Fi coverage area as the printer. The distance between the devices should not exceed 10-15 meters to ensure reliable signal reception during the initial pairing. Signal frequency 2.4 GHz is the preferred frequency for this model as many older printing devices do not support the 5 GHz standard.
WPS method: quick connection without entering a password
The easiest way to integrate a printer into a home network is to use technology WPS (Wi-Fi Protected Setup). This method allows you to transfer security settings automatically, without having to manually enter a complex password on a small screen or using the device's buttons. Most modern routers support this feature.
Find the WPS button on your router. It may be a physical button or a software button in the admin interface. Press this button. Within two minutes, press and hold the wireless button on the control panel. HP Laser 135wr more than 2 seconds. The Wi-Fi indicator will start blinking, indicating the search and connection process.
- 📡 Make sure the WPS light on your router is on or the security light is blinking.
- 🖨️ On the printer, the wireless network indicator should blink slowly and then turn solid.
- 🔒 The pairing process may take up to 2 minutes, do not turn off the devices during this time.
If the connection is successful, the wireless indicator on the MFP will stop flashing and turn solid blue. This means that IP address The device is now ready to use. You can now install the drivers on your computer, selecting the "Wireless" connection type during installation.
What to do if WPS doesn't work?
Some ISPs or router models may have WPS disabled by default for security reasons. In this case, access your router settings via a browser (usually 192.168.0.1 or 192.168.1.1) and find the Wireless or Wi-Fi section to enable this option. If activation is not possible, use the USB cable connection method described below.
Setup via USB cable and software
If the automatic method doesn't work or your router doesn't support WPS, the most reliable option is to use the installation software. To do this, you'll need a USB Type-B (printer) cable and a computer running Windows or macOS. This method allows the installation software to automatically retrieve the Wi-Fi settings from the system and transfer them to the printer.
Download the full package of drivers and utilities for the model HP Laser 135wr From the manufacturer's official website. Do not use the included discs, as the software versions on them may be outdated and not contain the latest modules for new operating system versions. Run the installer and follow the on-screen instructions.
When the program asks about the connection type, select "Wireless connection." Next, you'll be asked to connect the device via cable. At this point software wizard The printer will detect the printer and prompt you to send it a list of available networks. Select your network from the list and enter the password. After confirmation, you can disconnect the cable.
☑️ Installation Preparation Checklist
It's important to note that after transferring the settings, the USB cable is no longer needed for network operation, but it's worth saving it for future diagnostics. If an error occurs during installation, try temporarily disabling your antivirus or firewall, as they may be blocking the device from being detected on the local network.
Using the HP Smart app for mobile devices
For smartphone and tablet users, the most convenient tool is the app HP SmartIt's available in the Google Play and Apple App Stores. This method is especially useful if you don't have a computer with a USB port or want to set up printing directly from your mobile device.
Launch the app and click the "Add a new printer" button. The app will ask you to enable Bluetooth on your smartphone to detect the device. Make sure your phone is connected to the same Wi-Fi network you want to connect the printer to. HP Smart will automatically detect the 135wr model in setup mode.
| Setup stage | User action | Device response |
|---|---|---|
| Search | Pressing "+" in the app | The Wi-Fi indicator is blinking |
| Authorization | Entering the Wi-Fi password | The printer is receiving data |
| Update | Consent to software update | Reboot and install |
| Conclusion | Print a test page | The indicator lights up steadily |
During the setup process, the application may prompt you to update the printer firmware. Agree to the update, as new firmware versions often contain fixes for connection errors with modern routers. After the update, your device will reboot and be ready to print documents, photos, and scan directly from the app interface.
Solving common connection problems
Even if you follow the instructions carefully, situations may arise where the printer doesn't see the network or can't connect to it. Often, the problem lies in the router's security settings. For example, if filtering by MAC addresses, you need to whitelist the printer's address in the router settings. You can find the address by printing a network configuration report (by clicking the Report/Info button).
Another common cause of connection failure is using a hidden SSID (a network that doesn't broadcast its name). In this case, automatic detection won't work. You'll have to manually enter the network name, taking care to ensure proper case, or temporarily make the network visible in your router settings. Also, check if your router limits the number of devices that can connect.
⚠️ Important: If you're using a guest Wi-Fi network, make sure client isolation is disabled in your router settings. Otherwise, your computer won't see the printer, even if both are connected to the same network.
If all else fails, try changing the Wi-Fi channel on your router. Sometimes interference from neighboring networks on channel 6 or 11 can prevent a stable connection. Switching to channel 1, 3, or 9 often resolves the printer "dropping out" of the connection. It's also worth checking if the router is set to wireless only. 802.11n or 802.11ac, try setting the mixed mode (b/g/n).
Setting up a static IP address for stable operation
For office use, where multiple users access the printer, it's recommended to assign a permanent IP address to the device. This will prevent situations where, after a router reboot, the printer receives a new address, and computers lose access to it because the drivers are "looking" for the old one.
There are two ways to do this. The first is through the printer's web interface (EWS). To do this, enter the printer's current IP address in the browser's address bar. Go to Network -> IPv4 and select "Manual IP." Enter the address, mask, and gateway. The second method is to reserve the MAC address in your router's DHCP settings, which is often the preferred option.
When configuring manually, ensure the selected IP address is outside the range assigned by the DHCP server to avoid conflicts. For example, if your router assigns addresses from 100 to 200, assign the printer address 50. Gateway and DNS servers must match the address of your router.
Why can't my HP 135wr printer see my Wi-Fi network?
The issue is most likely related to the frequency range. The 135wr model only supports the 2.4 GHz standard. If your router only broadcasts 5 GHz or combines them into a single network with 5 GHz prioritized, the printer may not see the network. Separate the networks in your router settings or ensure 2.4 GHz mode is enabled.
How do I find out my printer's IP address if it doesn't print?
You can find the address in the HP Smart app under Printer Information. You can also print a network configuration report by holding down the Cancel button and the Wireless button simultaneously for a few seconds (the combination may vary, check the manual). Alternatively, view the client list in the router's web interface.
Can the HP 135wr be connected to a hidden Wi-Fi network?
Yes, but automatic detection won't work. You'll need to use the USB cable setup method and HP software, where you can manually enter the hidden network name (SSID) and security settings.
What does a blinking blue wireless light mean?
A blinking blue light indicates the Wi-Fi module is enabled but not connected to the router. A solid blue light indicates a successful connection. If the light is off, the wireless module is disabled.
