The most common reason: your printer and router aren't on the same network band
HP printers often fail to connect because they're looking for a 2.4 GHz network while your router is broadcasting only 5 GHz, or vice versa. Most home routers broadcast both bands at once, but some are set to 5 GHz only—which older HP printers cannot see. Your printer's manual or the sticker on the back will tell you which band it supports; if it says 802.11b/g/n, it needs 2.4 GHz.
The second most common reason is that your printer and router are too far apart or blocked by walls and metal objects. WiFi signals weaken over distance and through obstacles. If your printer is in a back bedroom and your router is in the front living room with a kitchen wall between them, the signal may be too weak to connect or stay connected.
A third frequent cause is that your printer's WiFi module needs a restart, or your router needs to forget and re-discover the printer. This is not the same as restarting—it means clearing the stored connection and starting fresh.
Key Takeaways
- Check whether your printer supports 2.4 GHz, 5 GHz, or both, then verify your router is broadcasting the band your printer needs.
- Move your printer closer to your router or remove physical barriers between them; WiFi range is typically 30 to 50 feet in an open space.
- Restart both your printer and router by unplugging them for 30 seconds, then plug them back in and wait for them to fully boot.
- Use HP's Smart app or your printer's control panel to forget the WiFi network, then reconnect by entering your network password again.
- If your router has a WPS button, press it, then press your printer's WiFi button within two minutes for automatic connection without typing a password.
Check your router's WiFi bands and your printer's capabilities
Log into your router's settings through a web browser or your router's app. Look for the WiFi settings page and check what bands are currently active. Most routers have a label on the back or bottom listing the model number; you can search that model online to find the manual, which explains how to access settings.
Once you're in the router settings, look for a section called "WiFi", "Wireless", or "2.4 GHz / 5 GHz". If you see two separate networks listed (often one ends in "-2.4" and one in "-5"), your router is broadcasting both bands and you can choose which one to use. If you see only one network name, check whether it's set to 5 GHz only. If it is, you'll need to enable 2.4 GHz or switch to a mixed mode that broadcasts both.
Now check your HP printer's manual or the specifications on HP's website. Search for your printer model number (usually on the front or back of the device) and look for "wireless specifications" or "WiFi bands supported". If it lists only 802.11b/g/n, it needs 2.4 GHz. If it lists 802.11ac or 802.11ax, it can use 5 GHz, but most HP printers support both.
Move your printer closer to the router or remove obstacles
WiFi signals travel best in straight lines and weaken through walls, metal, and water. A printer in a basement or garage will struggle to connect to a router on the second floor. If your printer is more than 30 to 40 feet from your router, or if there are multiple walls between them, move one or both devices closer together temporarily to test the connection.
Metal filing cabinets, refrigerators, microwave ovens, and metal-framed furniture all block or weaken WiFi signals. If your printer sits near any of these, move it a few feet away and try connecting again. Even a large aquarium or a mirror can reduce signal strength.
If moving the printer permanently is not practical, consider moving your router to a more central location in your home, or purchasing a WiFi extender or mesh network system to boost the signal in the room where your printer lives.
Restart your printer and router completely
A restart clears temporary errors that prevent connection. Unplug your printer from the power outlet and wait 30 seconds. While it's unplugged, unplug your router as well. Wait another 30 seconds, then plug the router back in first and wait for all its lights to stabilize (usually 1 to 2 minutes). Then plug the printer back in and wait for it to fully boot.
This is different from using a power button or sleep mode. The printer and router must be completely without power for at least 30 seconds. Many connection problems resolve after a full restart because it clears the WiFi module's memory and forces both devices to re-establish communication from scratch.
Forget the network and reconnect with your password
On your HP printer, locate the WiFi or network settings. This is usually accessed through a menu button on the printer's control panel or touchscreen. Look for "Settings", "Network", or "WiFi". Once you're in the network menu, find the option to view saved networks or "Forget Network". Select your WiFi network name and choose "Forget" or "Remove".
After forgetting the network, go back to the WiFi menu and select your network name from the list of available networks. When prompted, enter your WiFi password exactly as it appears—passwords are case-sensitive, so uppercase and lowercase letters matter. If you're unsure of your password, check the sticker on your router or log into your router's settings to view or reset it.
If your printer has a touchscreen, it may show a keyboard for typing. If it has only buttons, you may need to use the arrow keys to select letters. Take your time and double-check each character before confirming.
Use WPS (WiFi Protected Setup) for automatic connection
Many HP printers and routers support WPS, a feature that connects devices without typing a password. Look for a button labeled "WPS" on your router—it's usually on the back or side. Press and hold this button for 3 seconds until a light blinks or you hear a beep. You then have about two minutes to press the WiFi button on your printer (or select "WPS" from the printer's network menu).
The two devices will communicate automatically and connect without you entering a password. This method works well if your printer's control panel makes typing difficult, or if you're unsure whether you're entering your password correctly.
Not all routers have a physical WPS button—some allow you to enable WPS through the router's settings app or web interface. Check your router's manual if you don't see a button on the device itself.
Check for interference from other devices and networks
WiFi operates on radio frequencies that other devices also use. Cordless phones, microwave ovens, baby monitors, and wireless speakers can all interfere with WiFi signals, especially on the 2.4 GHz band, which is crowded. If your printer connects intermittently or drops connection frequently, interference may be the cause.
Open a WiFi analyzer app on your phone or computer (search your device's app store for "WiFi analyzer" or "WiFi scanner"). This app shows all the networks in your area and which WiFi channels they're using. If many networks are using the same channel as yours, your router may be switching to a less crowded channel. Check your router's settings and manually select a channel that fewer neighbors are using—channels 1, 6, and 11 are the standard non-overlapping options on 2.4 GHz.
If interference is severe, moving your router away from the microwave or cordless phone base, or switching to 5 GHz (if your printer supports it), can improve stability.
Update your printer's firmware and check for driver issues
HP periodically releases firmware updates that fix WiFi connection problems. Visit HP's support website, enter your printer model number, and read the latest firmware. Follow HP's instructions to install it—most updates are done through the printer's control panel or by connecting the printer to a computer with a USB cable.
If your printer is already connected to your computer via USB, you may also need to update the printer driver on that computer. Go to HP's website, search for your printer model, and read the latest driver for your operating system. Install it and restart your computer. Sometimes a driver update resolves WiFi issues even if the printer is not currently connected wirelessly.
Frequently Asked Questions
Why does my HP printer connect to WiFi but then disconnect after a few minutes?
This usually means the signal is weak or interference is disrupting the connection. Move your printer closer to the router, remove obstacles between them, or switch to a less crowded WiFi channel. If the problem persists, check whether your router's WiFi band setting has changed—some routers automatically switch bands, which can disconnect older printers.
My printer won't find my WiFi network at all. What should I do?
First, confirm your printer supports the band your router is broadcasting. If your router is set to 5 GHz only and your printer supports only 2.4 GHz, the printer won't see the network. Enable 2.4 GHz in your router settings, or check your printer's manual to confirm it supports 5 GHz. Then restart both devices and try again.
Can I connect my HP printer to WiFi using my phone?
Yes, if you have the HP Smart app installed on your phone. Open the app, select "Add Printer", and follow the prompts. The app will guide your printer through the connection process. This method works well if your printer's control panel is difficult to use for entering passwords.
What if I forgot my WiFi password?
Check the sticker on your router—most routers have the default password printed there. If you've changed the password and forgotten it, log into your router's settings through a web browser (usually by typing your router's IP address, often 192.168.1.1, into the address bar). You'll need your router's admin username and password, which are also on the sticker. Once logged in, you can view or reset your WiFi password.
Does my HP printer need to be on the same network as my computer?
Yes, for wireless printing to work, your printer and computer must be connected to the same WiFi network. If your computer is on a guest network and your printer is on the main network, they won't communicate. Check that both devices are connected to the same network name.
