Game console PlayStation 4 Slim is one of the most popular devices for home entertainment, but to unlock its full potential, it requires a stable internet connection. Without internet access, it's impossible to download system software updates or download new games from PlayStation Store or participate in multiplayer battles. Modern titles weigh tens of gigabytes, so using a wired connection isn't always convenient or physically possible due to the distance to the router.
The process of setting up a wireless connection on this console model has been simplified by the developers and takes just a few minutes if you know where to look for the necessary settings. You don't need any special network administration skills or complex equipment—all you need is your home network password. In this article, we'll walk you through each setup step in detail, explore possible errors and troubleshooting methods, and offer tips for optimizing download speeds.
Before you begin setting up the menu, make sure your wireless router is turned on and broadcasting a signal, and that the console itself is within a strong reception area. Wi-Fi module The PS4 Slim operates in dual bands, allowing you to flexibly configure your connection based on network congestion. Proper configuration at launch will eliminate lag in online games and long waits for patches.
Equipment preparation and compatibility testing
The first step before starting setup is physical preparation and checking the basic operating conditions of the equipment. Console PlayStation 4 Slim equipped with a built-in wireless communication module that supports standards IEEE 802.11 a/b/g/n/ac, which ensures high data transfer speeds. It's important to understand that for maximum performance, it's best to use the 5 GHz band if your router supports it, as it's less congested by neighboring networks.
Make sure you know the exact name of your network (SSID) and the password. If you plan to use a hidden network, you'll need to enter the name manually, as automatic search won't detect it. It's also worth checking that MAC address filtering isn't enabled on your router, as this could block new devices even if the password is entered correctly.
⚠️ Warning: If your router uses WEP security mode or older encryption protocols, the console may fail to connect or may become unstable. We recommend switching your router settings to WPA2-PSK or WPA3 for maximum security and compatibility.
The distance between the console and the router plays a critical role in connection stability. Walls, especially load-bearing ones, and household appliances can significantly weaken the signal. If you notice the loading indicator flickering, try moving the console closer to the signal source or using a Wi-Fi repeater to boost coverage in the room.
Step-by-step instructions for connecting to the network
The process of setting up the internet on the console is done through the system's main menu. To begin, turn on your PS4 Slim and log in to your user profile. On the top horizontal menu bar, find the suitcase icon, which represents the section SettingsThis is where all system parameters are concentrated, including network connection management.
Once you enter the settings menu, scroll down to the item Net. Select it and in the submenu that opens, click on the option Set up an Internet connectionThe system will offer two options: using a LAN cable or Wi-Fi. Select Use Wi-Fi, after which the console will begin scanning for available wireless networks within range.
☑️ Check before connection
In the list of found networks, find your router's name and press the X button on the controller. If your network is hidden, select Other and enter the SSID manually using the keyboard. Next, you'll be asked to enter the password. Be careful when entering characters, as the system is case-sensitive. After successfully verifying the password, the console will attempt to obtain an IP address automatically.
- 📡 Select "Use Wi-Fi" as the connection type.
- 🔍 Find your network in the list of available ones or select "Other" to enter it manually.
- 🔑 Enter your wireless network password, being careful about the case of the characters.
- ✅ Leave your IP and DNS settings on "Automatic" unless your ISP has given you other instructions.
Manual DNS and IP address configuration
In some cases, automatically obtaining settings can lead to errors or slow download speeds. If the default connection is unstable, it may be worth switching to manual settings. In the network settings menu, when the system asks about the IP address configuration method, select Manually instead of "Automatically".
You'll need to enter the IP address, subnet mask, and gateway. This information is usually the same as your router's address, but with the last digit changed. For example, if your router's address is 192.168.1.1, you could assign 192.168.1.50 to the console. Pay special attention to the primary and secondary DNS fields. Using public DNS servers, such as Google or Cloudflare, can often speed up system response times and resolve access issues. PlayStation Network.
Example of manual entry of settings:IP address: 192.168.1.150
Subnet mask: 255.255.255.0
Gateway: 192.168.1.1
Primary DNS: 8.8.8.8
Secondary DNS: 8.8.4.4
After entering all the numerical values, the system will prompt you to configure the MTU. It is better to leave the value at this point. Automatically, as incorrect packet sizes can lead to connection interruptions in games. Finally, check your proxy server: if you're not using dedicated corporate networks, select Do not use.
Why change DNS?
Changing DNS servers helps bypass ISP blocks and speed up searching for game server domains. ISPs often use slow servers by default, causing delays when connecting to Sony online services. Public DNS servers are faster and more stable.
Connection diagnostics and speed testing
After entering all parameters, the system will prompt you to test your internet connection. This step is critical, as it reveals the true capabilities of your connection. The console will perform a sequential test: first, it will attempt to obtain an IP address, then test internet access, and finally, perform a download and upload speed test.
Test results are displayed in megabits per second (Mbps). For comfortable online gaming, a stable ping is more important than maximum speed, although speed is also important for downloading games. If the test shows errors during the IP address acquisition stage, the problem lies with the router or incorrect data entered. An error during the internet connection test may indicate issues with the internet provider.
| Test stage | Status | Possible cause of the error |
|---|---|---|
| Obtaining an IP address | Success/Error | Incorrect password, DHCP failure on the router |
| Internet connection | Success/Error | ISP issues, MAC blocking |
| Connecting to PSN | Success/Error | Sony services are unavailable, date/time error |
| Download speed | Numeric value | Channel load, distance to the router |
Please note the NAT type value displayed after a successful test. Type 1 (Open) is ideal, while Type 2 (Moderate) is the norm for most home networks and allows for seamless gaming. Type 3 (Strict) may cause difficulties connecting to some players or voice chats.
Solving common connection problems
Even with the correct settings, users may experience intermittent connection disconnections or the inability to log in. One common cause is system time desynchronization. If the console's date and time are significantly different from the actual time, security certificates will fail, and the connection to Sony's servers will be lost.
You should also consider overheating of the network module or router. The console heats up during prolonged gaming, and if the ventilation is blocked, the Wi-Fi module may work intermittently. In such cases, a hardware reboot helps: turn off the console completely (not in sleep mode), unplug the router for 30 seconds, and then turn all devices back on.
⚠️ Please note: The PlayStation system interface and password security requirements are subject to change. If standard methods don't work, please check the official PlayStation Network service status, as the issue may be with Sony's servers and not your hardware.
If nothing helps, try resetting your network settings to factory defaults. To do this, go to the menu Settings → Network select an item Set up an Internet connection, press the Options button on the controller and select Reset settingsThis will delete all saved Wi-Fi profiles and allow you to start setup from scratch.
Optimizing Wi-Fi signal for gaming
To ensure the best gaming experience, it's important to minimize signal interference. If you're using the 2.4 GHz band, you may encounter interference from microwave ovens, Bluetooth devices, and neighboring routers. Switching to the 5 GHz band in your router settings (if your console and router support it) will significantly improve connection stability.
The placement of your router's antennas is also important. Antennas should be vertical to ensure horizontal signal propagation. If the router is placed on the floor or in a closed cabinet, the signal quality will be poor. Elevate the device and ensure it has adequate space on all sides.
If the signal in the room where the console is located is initially weak, consider purchasing a Wi-Fi repeater or using Powerline adapters, which transmit internet through electrical wiring. This will allow you to create a wired connection to any outlet in the apartment, which is always preferable to a wireless connection for a gaming console.
Why can't my PS4 Slim see my Wi-Fi network?
Most often, the problem stems from incompatible channels or encryption standards. Make sure your router isn't using channels higher than 11 (for the US region) or the N/AC-only mode, which older firmware versions may not support. Try changing the channel on your router to 1, 6, or 11 and switching the mode to mixed (b/g/n).
How to speed up game downloads over Wi-Fi?
Put your console into rest mode with the "Stay connected to the internet" feature enabled. This mode often speeds up downloads because the system doesn't waste resources rendering the interface. Also, close all running games and applications before starting a download.
What to do if error NW-31456-9 does not disappear?
This error is often related to DNS issues. Try manually entering Google's DNS servers (8.8.8.8 and 8.8.4.4) or Cloudflare's (1.1.1.1) in your network settings. A full network reset and reinstallation of system software in Safe Mode also helps.
