How to connect the Ricoh SP 150suw printer to Wi-Fi: A complete guide with photos and tips

Connecting a printer Ricoh SP 150suw Connecting to a wireless network is a task that seems simple only at first glance. In practice, users encounter non-obvious router settings, frozen printer indicators, or sudden errors like Wi-Fi Connection FailedThis article won't just retell the instructions from the manual - we'll break it down all stages Taking into account typical problems, we will teach you how to check signal quality and optimize network parameters for stable operation.

Feature of the model SP 150suw in that it supports both classic connection via WPS (one button), and manual entry of network parameters. However, not all routers work correctly with WPS, and you have to manually enter not only the SSID and password, but also encryption type, network mode (2.4 or 5 GHz) and even broadcast channelWe'll cover each of these parameters in detail—you'll understand why your printer isn't seeing the network or constantly losing connection.

Important: If you have previously tried to connect the printer and received errors, reset its settings before you start. To do this, hold down the button Stop (red) for 10 seconds until all lights turn off. This will clear saved Wi-Fi profiles and restore factory settings.

1. Preparing the router: what settings to check before connecting

Most connection issues Ricoh SP 150suw Wi-Fi is not connected to the printer, but to incorrect router parametersBefore you begin setting up your device, make sure your network meets the following requirements:

📶 Frequency range: The printer only works online. 2.4 GHzIf your router broadcasts simultaneously on 2.4 and 5 GHz with the same SSID, divide the networks in the settings (for example, name them MyWiFi_2G And MyWiFi_5G).
🔒 Encryption type: only supported WPA2-PSK (AES) or WPA3-PSK. Disable outdated ones WEP or TKIP — the printer does not recognize them.
📡 Broadcast channel: Avoid automatic channel selection. Set it manually. 1, 6 or 11 - they are least susceptible to interference from neighboring networks.
🔄 Opening hours: disable the function 802.11r (Fast Roaming) - it may interfere with a stable printer connection.

To check your current settings, go to your router's web interface (usually at 192.168.0.1 or 192.168.1.1>) and find the section Wireless network (Wi-Fi) or Wireless SettingsIf you're unsure of the settings, take screenshots of your current settings—this will help you restore them if you make a mistake.



⚠️ Attention: Some providers (such as Rostelecom or Beeline) block access to router settings by default. If you can't access the control panel, contact technical support and request login information (logins and passwords are often found on a sticker on the router itself).

2. Method 1: Connecting via WPS (the fastest method)

If your router supports the technology WPS (Wi-Fi Protected Setup), connecting the printer takes less than a minute. This method doesn't require a password—data is transferred automatically after pressing a button on the router. Here's how it works:


  Make sure the printer Ricoh SP 150suw turned on and within the network range (no further than 2–3 meters from the router).
  Press and hold the button Wi-Fi on the front panel of the printer for 3 seconds until the indicator Wireless will not start blinking quickly.
  For 2 minutes press the button WPS on the router (usually it is signed or marked with the 🔄 icon).
  Wait for the indicator Wireless the printer won't light up green (this will take 30-60 seconds).


If the indicator continues to flash or lights up orange, this means the connection failed. This could be due to:


  ❌ The router does not support WPS (check the model in the documentation).
  ❌ The WPS function is disabled in the router settings (enable it in the section Wi-Fi → WPS).
  ❌ Sync timed out (try again by holding the button Wi-Fi on the printer longer).


💡If your router doesn't have a physical WPS button but supports the feature, try enabling it programmatically. To do this, open the router's web interface and find the "WPS" section. WPS and activate the option PBC (Push Button Configuration). Then repeat the connection steps.

⚠️ Attention: Some providers (such as MTS) disable WPS by default for security reasons. If you can't find this feature in the settings, use manual connection method.

3. Method 2: Manual connection via the printer panel

If WPS doesn't work or your router doesn't support it, you'll have to enter your network settings manually. To do this:


  Press the button on the printer Menu (menu).
  Go to the section Network → Wireless LAN → Setup Wizard.
  Select your network from the list (if it is not there, check if the SSID is hidden in the router settings).
  Enter your Wi-Fi password. Use the buttons ▲/▼ to select characters and OK for confirmation.
  Confirm saving the settings. The printer will reboot and attempt to connect.


The main difficulty of this method is entering passwordThe printer screen only displays two lines, and characters must be selected one at a time. To simplify the process:


  🔑 Use a simple password (eg. 12345678) during setup, then change it in the router.
  📱 Write down your password on paper or take a photo of it—this will speed up entering it.
  🔄 If the printer displays an error Authentication Error, check the case of the characters (the password is case sensitive!).


☑️ Preparing for manual connection
The Wi-Fi password is written down on paperThe printer is on and in standby mode.The router is not in "guest network" mode.The network SSID is visible on other devicesCompleted: 0 / 4

If the printer still does not connect after entering the password, check:

  🔌 Router power supply: Sometimes after changing the settings it needs to be rebooted.
  📶 Signal level: If the printer is located far from the router, try temporarily moving it closer.
  🔄 Compatibility mode: enable it in your router settings WPA2/WPA3 Transition Mode (if any).


4. Checking the connection and printing a test page

After successful connection, you need to make sure that the printer interacts correctly with the network and ready to print. To do this:


  Press the button on the printer Menu → Reports → Network Configuration.
  The printer will print a sheet with network settings. Check the following lines:
    
      SSID - must match the name of your network.
      IP Address - if specified 0.0.0.0, connection failed.
      Signal Strength — the signal level must not be lower 70%.
    
  
  If everything is ok, print it out test page: Menu → Reports → Test Print.


Critical point: if the report contains an IP address of the type 169.254.x.x, this means the printer didn't receive an address from the router (DHCP failed). In this case, go to the router settings and check if the DHCP server is enabled, or assign it to the printer. static IP manually.

How to assign a static IP address to a printer in a router
1. Go to the router's web interface (usually 192.168.0.1).
2. Find the section DHCP → Static Lease (or Address reservation).
3. Enter the MAC address of the printer (found on the sticker on the back) and assign an IP outside the DHCP range (e.g. 192.168.0.100).
4. Save the settings and restart the printer.


If the test page does not print, but the printer is connected to the network, the problem may be:

  🖨️ Drivers: Make sure you have the latest driver installed on your computer Ricoh SP 150suw (download from official website).
  🔌 Firewall: Temporarily disable your antivirus or Windows Firewall—they may be blocking access to the printer.
  📡 Interference: If there are other wireless devices (microwaves, cordless phones) nearby, try changing the Wi-Fi channel in the router settings.

💡90% of Ricoh SP 150suw Wi-Fi connection issues can be resolved by configuring the router (setting the correct channel, encryption type, and 2.4 GHz band). Only 10% of the time is the printer itself or its firmware at fault.

6. Optimize Wi-Fi for stable printing

Even if the printer is connected, problems may arise over time communication breakdowns or "freezing" when printing. This is due to:

  📉 Signal level drop: If the printer is located far from the router, the signal may weaken.
  🔄 Automatic channel switching: The router may change the channel, and the printer may not have time to adjust.
  🖥️ Network congestion: If several devices (smartphones, smart TVs) are running at the same time, there is not enough bandwidth.


To improve stability:

  Go to your router settings and fix the channel (For example, Channel 6 with width 20 MHz).
  Turn on QoS (Quality of Service) and set high priority for the printer by MAC address.
  If possible, connect the printer to the router via Wi-Fi repeater (repeater) to strengthen the signal.
  Update your router firmware to the latest version (this fixes compatibility issues).


To check the signal quality:

  Print the network report (Menu → Reports → Network Configuration).
  Find the line Signal StrengthThe optimal value is 80–100%.
  If the level is lower 50%, move the printer or router.


💡If you have a dual-band router, try disabling the 5 GHz network while setting up the printer. Sometimes devices confuse the bands, even if you select 2.4 GHz.

7. Connecting the printer to a computer or smartphone

After setting up Wi-Fi on the printer itself, you need to add it to the system on your devices. Instructions vary depending on the OS:

For Windows 10/11:
