Changing internet service providers often entails replacing the router or, at a minimum, changing local network settings, such as the SSID and password. At this point, owners of office and home devices face an unpleasant situation: HP printerA device that was printing documents reliably just yesterday stops responding to computer requests. The device simply doesn't see the new access point, as its memory still contains the old router's configurations.
Restoring a wireless connection requires not only entering a new password, but often a complete reset of the printer's network settings. Modern models Hewlett-Packard have complex network module logic that may conflict with new security protocols or frequency ranges. It is critically important to understand that without a complete reset of the printer's network settings (Network Reset), connecting to the provider's new equipment is often impossible.
In this guide, we'll cover detailed steps for various scenarios, from automatic configuration via WPS to manually entering TCP/IP parameters. You'll learn how to avoid common errors associated with the 2.4 GHz and 5 GHz frequency bands and how to get your computer to "see" your printer on the shared network again.
Why does my printer stop seeing the network after replacing the router?
The main reason for connection loss is that the printer's network adapter stores static data about its previous environment. When you change providers, the router itself often changes as well, which means the gateway MAC addresses and DHCP parameters change. The printer continues to "knock" on the door of the old address, which no longer exists on the air.
In addition, new routers from modern providers often activate the mode by default. dual-band operation (Dual Band), combining 2.4 GHz and 5 GHz networks under a single name. Older HP printing equipment may incorrectly process this signal, attempting to connect to a 5 GHz frequency their module does not support, or, conversely, ignoring the mixed signal.
⚠️ Note: If your new router uses the WPA3 encryption standard and your printer is more than 5-7 years old, it may not physically support this security protocol. You will need to temporarily enable WPA2/WPA Mixed compatibility in your router settings.
It's also worth considering that changing your provider's equipment may have changed the range of IP addresses being distributed. If your network was previously pooled, 192.168.0.x, and the new router distributes addresses from the pool 192.168.1.x, the static IP address stored in the printer's memory will become invalid. The computer and printer will be on different subnets, making printing impossible.
Preparing for Reset: Resetting Network Settings
Before attempting to pair the devices, you must clear the printer's network module memory of old entries. This will restore the network settings to factory defaults without affecting other device parameters, such as paper settings or print quality.
For most HP models with a control screen, the procedure is as follows: On the control panel, press the wireless button or go to the settings menu. Find the section Net or Network Setup, then select Restore network settings or Restore Network SettingsConfirm the action, and the device will restart the network module.
If you have a model without a display, such as a DeskJet or entry-level LaserJet series, use a key combination. This typically involves pressing and holding the keys simultaneously. Wireless communication And Cancel (cross) for 3-5 seconds until the power indicator starts flashing. After this, a configuration report will print, indicating that the settings have been reset.
☑️ Preparation checklist
It's important to make sure you know the exact name of your new network. Pay attention to the case: MyWiFi And mywifi These are different networks for your equipment. Also, check if your new provider uses a hidden SSID, which would require you to manually enter the network name.
WPS method: the fastest way to connect
Technology Wi-Fi Protected Setup (WPS) allows you to connect devices without entering a password, simply by pressing a button on the router. This is ideal if you just installed a new router from your provider and don't want to mess around with manually entering complex characters.
Find the button marked on the router body WPS or the two arrows icon. Press it once (don't hold it too long, or you'll reset the router). The WPS indicator on the router should blink, indicating it's searching. Within 2 minutes, approach the printer.
On the printer control panel, press the wireless button or select from the menu Wi-Fi settings -> Wi-Fi Protected SetupThe device will begin searching for a signal. Once a connection is established, the wireless network indicator on the printer will glow solid blue or green.
| HP model | Action for WPS | Success indicator | Possible problems |
|---|---|---|---|
| HP LaserJet Pro | Wireless Button > WPS | The blue indicator is constantly on | Timeout if not pressed within 2 minutes |
| HP DeskJet | Button "Wi-Fi" + "Information" | Flashing blue, then staying on | Conflict with the WPS button on the router |
| HP OfficeJet | Menu > Network > WPS | "Connected" message on the screen | Network reset required before starting |
| HP Smart Tank | Wireless button | The indicator lights up blue | Firmware update required |
⚠️ Note: Some ISPs disable the WPS feature on their routers by default for security reasons. If the button on your router doesn't respond, check the router's web interface and enable WPS in the wireless network settings.
What to do if WPS doesn't work?
If automatic connection fails, your router may be using a non-standard channel or channel width. Try setting the channel width to 20 MHz for the 2.4 GHz network in your router settings and fixing the channel (e.g., 1, 6, or 11), then try WPS again.
Manual setup via the printer control panel
If automatic methods fail, you'll have to use the classic manual entry method. This method is the most reliable, as it eliminates automatic recognition errors. You'll need the exact network name (SSID) and password.
On the touch screen or using the navigation buttons, navigate to the menu Settings (gear icon). Select the item Net or Wireless communication. Launch Wireless Network Setup Wizard (Wireless Setup Wizard). The device will begin scanning the air.
In the list that appears, find the name of your new network. If the list is long, scroll. Note that 2.4 GHz and 5 GHz networks may appear as separate access points. Select the one that matches your printer's capabilities (usually 2.4 GHz).
After selecting the network, a virtual keyboard will open. Enter the Wi-Fi password. Be careful with the case of letters and other symbols. After entering, press Ready or OKThe printer will attempt to obtain an IP address from the router.
Using a USB cable for initial configuration
When wireless methods fail, time-tested technology comes to the rescue USB cableThis method allows you to transfer Wi-Fi settings directly from your computer to the printer, bypassing complex menus on the device itself. This is especially useful for models without screens.
Connect the printer to your computer via USB cable. Make sure the drivers are installed. Open the program. HP Printer Assistant or go to Devices and printers in the Windows Control Panel. Find your printer, right-click it, and select Printer properties or Setup and software.
Select the option from the menu Convert USB connection to wireless (Convert a USB connection to wireless). The setup wizard will prompt you to select your new network from a list of available ones. Enter the password, and the program will automatically transfer the configuration to the printer's Wi-Fi module.
HP Smart steps (alternative):1. Connect the printer via USB.
2. Open HP Smart.
3. Click "+" (Add printer).
4. Select "Change Wi-Fi settings".
5. Follow the instructions on the screen.
After successfully transferring the settings, the program will prompt you to disconnect the USB cable. The printer should automatically connect to the network, indicated by the indicator flashing and then turning solid.
Compatibility Issues: 2.4 GHz and 5 GHz Bands
One of the most common problems when switching providers is frequency incompatibility. Most new routers support two bands, but many HP printers (especially those older than 3-4 years) only support one band. 2.4 GHz.
If your new router combines both networks under a single name (Smart Connect), the printer may attempt to connect to the 5 GHz band, fail, and not automatically switch to 2.4 GHz. The solution lies in the router settings: you need to log into its web interface (usually at 192.168.0.1 or 192.168.1.1) and separate the networks by giving them different names, for example, HomeWiFi And HomeWiFi_5G.
Connect the printer to the network with the ending _2.4G Or simply without a 5G set-top box. Make sure your computer is also connected to the same 2.4 GHz network at this time, as devices in different frequency bands (even with the same name) may not be able to see each other on the local network.
Frequently Asked Questions (FAQ)
Is it possible to set up an HP printer without a computer, just from a phone?
Yes, it is possible through the app. HP Smart for iOS or Android. The main requirement is that the phone must be connected to the new Wi-Fi network, and Bluetooth must be enabled on the phone for initial printer detection. The app will automatically transfer the network passwords to the device.
The printer is connected to Wi-Fi, but the computer says "Offline." What should I do?
Most likely, after changing the router, the printer's IP address changed, but the old port remained in the system. Go to Devices and printers, select properties tab Ports and add a new port of the Standard TCP/IP type, entering the current IP address, which can be found by printing a network configuration report on the printer itself.
Do I need to reinstall drivers after changing my provider?
Typically, no, unless you're upgrading your operating system. However, if the printer isn't automatically detected, removing the old device from the printer list and reinstalling the full driver package from the official HP website often resolves port conflicts.
How to find out the IP address of a printer if there is no screen?
Press and hold the Wireless button or the Information button (the "i" icon) for 3-5 seconds. The printer will print a network configuration report, with the current IP address (e.g., 192.168.1.45) listed in the IPv4 section.
