My printer won't connect to Wi-Fi: Why it's not searching for a network and how to fix it.

Are you trying to print an important document, but the printer stubbornly refuses to detect your Wi-Fi network? Or is your device connecting to your router, but the connection drops after a minute? Wireless printer connection issues are one of the most common technical conundrums faced by users of both home and office devices. Unlike a wired connection, where everything boils down to the cable and port, Wi-Fi depends on dozens of parameters, from router settings to the printer's firmware.

In this article we will look at all possible reasons, why the printer is not searching for Wi-Fi - from the banal (the wireless module is turned off) to the exotic (IP address conflict on the local network). You will receive step-by-step instructions for diagnosing and resolving the problem, as well as checklists for quick verification. We will pay special attention to Canon, HP, Epson And Brother — brands whose printers most frequently "lose" the network. If your model is different, don't worry: the universal methods work for 90% of devices.

Before you move on to the settings, answer one question:

1. Checking basic settings: router and printer

Let's start with the obvious: Make sure Wi-Fi is turned on on the printer.Many models have a physical button or switch for the wireless module (for example, on Canon PIXMA MG3640 (This is the button with the antenna icon next to the power indicator.) If there is no button, check the device's menu:

• 📱 Click Menu → Settings → Wireless (or Wireless LAN).
• 🔄 Make sure your Wi-Fi status is — "On" (Enabled).
• 🔍 Run a network search manually (optional) Network search or Wi-Fi Setup).

If the printer still does not find the network, check router:

• 📡 Reboot your router (unplug it from the power outlet for 30 seconds).
• 🔌 Make sure the Wi-Fi indicator on your router is lit (usually green or blue).
• 📶 Check if another device (smartphone, laptop) can see the network. If not, the problem is with the router, not the printer.

Update your router firmware (if available) -->

🔴 Critical error: If the printer doesn't respond to buttons or doesn't turn on at all, the problem may be with the power supply or motherboard. In this case, you need to repair at a service center.

2. Incompatibility of Wi-Fi standards: 2.4 GHz vs. 5 GHz

Most printers (especially budget models before 2020) only support 2.4 GHz networks and do not see 5 GHz. If your router broadcasts both networks under the same name (SSID), the printer may freeze when attempting to connect. Solution:

• 📡 Separate networks in your router settings:

  192.168.1.1 → Wireless Network → 2.4 GHz and 5 GHz Settings → Split SSID

  Example: Call 2.4 GHz as MyWiFi_2G, and 5 GHz - MyWiFi_5G.

• 🔄 Reconnect the printer to the network MyWiFi_2G.
• 📌 For routers TP-Link, ASUS or Keenetic The path may differ. Look for the option Band Steering or Smart Connect And turn it off.

⚠️ Attention: some printers (eg HP OfficeJet Pro 9015) support 5 GHz, but only in mode 802.11a/n/acIf the router is operating in mode 802.11ax (Wi-Fi 6), try changing the standard to 802.11n in the settings.

3. Incorrect router security settings

Printers often "refuse" to connect to networks with complex security parameters. Check the following router settings (usually available at 192.168.0.1 or 192.168.1.1):

• 🔐 Encryption type: The printer may not support WPA3Switch to . WPA2-PSK (AES).
• 🔑 Complex password: If the password uses characters like #, $ or Cyrillic, try changing it to Latin with numbers (for example, MyPass123).
• 📡 Hidden network (Hidden SSID): If your network doesn't broadcast its name (SSID), the printer won't find it. Turn on visibility.
• 🔄 MAC address filtering: If enabled, add the printer's MAC address to the whitelist.

🔹 How to find the MAC address of a printer?

• Print test sheet (usually a button Info or Self-Test).
• Look at the sticker on the back/bottom of the device.
• In the printer menu: Settings → Network → MAC Address.

Where can I change the encryption type on my router?

On most routers the path is:

Wireless Network → Security Settings → Encryption Type.

For Keenetic: Home Network → Access Point → Security.

For TP-Link: Wireless → Wireless Security → Version (select WPA2-PSK).

⚠️ Attention: after changing the router's security settings all devices will be turned off from Wi-Fi. You'll have to reconnect them, entering a new password.

4. IP Addressing Issues: DHCP vs. Static IP

If the printer connects to the network, but after a few minutes “disappears” or the computer does not see it, the culprit is IP address conflict. Check:

• 🔄 DHCP mode: Make sure that automatic IP allocation is enabled on your router (DHCP Server should be Enabled).
• 📌 Static IP: If your printer has a fixed IP address but it conflicts with another device, change it manually.

  Example for a printer:
  IP: 192.168.1.100
  Mask: 255.255.255.0
  Gateway: 192.168.1.1
  DNS: 8.8.8.8

• 🔍 Printer ping: If the printer is online but not responding, check its accessibility from the PC:

  ping 192.168.1.100

  (replace IP with the current one).

🔹 How to assign a static IP to a printer?

1. Log into the printer's web interface (usually using the IP specified in the test print).
2. Go to Network → TCP/IP Settings.
3. Select Manual setup and enter the parameters (as in the example above).
4. Save and restart the printer.

5. Outdated printer firmware or drivers

Manufacturers regularly release printer updates that fix Wi-Fi connection issues. If your device isn't searching for a network, The first thing to do is update the firmware:

• 🖨️ For printers HP:
  1. Download HP Smart With official website.
  2. Connect the printer via USB.
  3. Run the program and follow the update instructions.
• 🖨️ For Canon: use the utility IJ Network Tool or update the firmware through the printer menu (Settings → Software Update).
• 🖨️ For Epson: Download the firmware from the website Epson, unzip and download via the printer's web interface.

⚠️ Attention: Do not disconnect the printer from the power supply during the firmware update, as this may damage the device. If the process freezes, wait 10-15 minutes, then restart the printer.

🔹 Updating drivers on your PC:

1. Open device Manager (Win + X → Device Manager).
2. Find the section Print queues.
3. Right-click on the printer → Update driver.
4. Select Automatic search.

6. External interference and weak Wi-Fi signal

If the printer is far from the router or there are obstacles between them (walls, furniture, appliances), the signal may be too weak. Check:

• 📶 Signal level: Print a network status report (optional) Wireless Report or Network → Diagnostics). If the signal level is lower 50%, move the printer closer to the router.
• 🛡️ Interference from other devices: Microwaves, cordless phones, and even neighboring Wi-Fi networks on the same channel can interfere. Try changing the channel on your router:

  192.168.1.1 → Wireless Network → Channel → Select 1, 6, or 11 (least congested)

• 🔄 Repeater or Mesh system: If your router doesn't cover the entire area, use a signal booster. Make sure the printer is connected to the main network, not the repeater (some models don't work with repeaters).

🔹 Interference test: Temporarily disconnect all devices except the printer and one PC. If the connection works, a conflict with another device is to blame.

7. Resetting the printer and router

If nothing helps, do the following: full reset on the printer and router. This will restore the devices to factory settings and fix any software glitches.

🔹 Resetting the printer:

• Press and hold the button Reset (or Stop/Reset) 10–15 seconds.
• For HP: Settings → Tools → Restore Default Settings.
• For Epson: Settings → Recovery → Network reset.

🔹 Resetting the router:

• Click the button Reset on the back of the router (use a paper clip).
• Hold for 10-30 seconds until the indicators flash.
• Reconfigure the router (network name, password, encryption type).

⚠️ Attention: After resetting the router, all connected devices (smartphones, TVs, smart speakers) will be disconnected. Save your settings or take a photo of them beforehand.

8. Alternative methods of connecting the printer

If Wi-Fi still doesn't work, try these alternative methods:

• 🖥️ Wired connection (USB/Ethernet): Most printers don't require Wi-Fi to print from a PC. Connect the device with a cable and install the drivers.
• 📱 Direct Printing (Wi-Fi Direct): modern printers (HP Envy, Canon Selphy) support access point mode. Activate it in the printer menu and connect directly from your smartphone.
• ☁️ Cloud Printing: services like Google Cloud Print (for older models) or HP Smart Allows online printing. Manufacturer account registration required.
• 🔌 Powerline adapters: If the router is far away, use adapters that transmit the Internet through electrical wiring (for example, TP-Link AV600).

🔹 Wi-Fi Direct vs Bluetooth: If your printer supports both standards, choose Wi-Fi Direct — It's more stable and faster. Bluetooth is only suitable for printing photos from a smartphone.

How to enable Wi-Fi Direct on a printer Canon PIXMA?

Settings → Wireless → Wi-Fi Direct → Turn on.

The connection password is usually indicated on the printer sticker or in the menu Wi-Fi Direct → Settings
