Why PlayStation 4 Shares Wi-Fi: The Console's Hidden Internet Connection Features

Many owners PlayStation 4 They're surprised to find an option to share the internet via Wi-Fi in the console's settings. At first glance, the game console has nothing in common with router functions, but Sony didn't integrate this feature by accident. In some scenarios PS4 as an access point It can be a real lifesaver—for example, when you need to connect a device without an Ethernet port to the network or temporarily replace a broken router.

In this article we will take a detailed look at Why is the PS4 technically capable of distributing Wi-Fi despite the lack of specialized hardware?, what modes are available, and how to properly configure the connection to avoid common speed and stability issues. You'll also learn about hidden nuances, from limitations on the number of connected devices to the impact on console performance during games.

Technical background: how the PS4 becomes a hotspot

Unlike full-fledged routers, PlayStation 4 It doesn't have a separate Wi-Fi module to distribute the signal. Instead, the console uses software emulation of an access point via the built-in adapter Broadcom BCM4356 (in models PS4 Slim And PS4 Pro). This chip was originally designed to connect the console to the network, but Sony added support for the mode SoftAP (Software Access Point), which allows the device to simultaneously:

• 🔄 Accept Internet via cable (Ethernet) or Wi-Fi (in bridge mode)
• 📶 Distribute to his other gadgets wirelessly
• 🎮 Support own network connection for gaming

It is important to understand that PS4 It's not a full-fledged router. It can't:

• ❌ Separate networks into different VLANs
• ❌ Filter traffic by MAC addresses
• ❌ Maintain modern standards Wi-Fi 6 or WPA3

However, the console's capabilities are sufficient for basic tasks—for example, connecting a smartphone, tablet, or a second computer. Speed ​​in this mode is limited. 72 Mbps (standard 802.11n), which is enough to watch videos in 1080p, but it may slow down when playing online and downloading files at the same time.

Two distribution modes: access point vs. bridge

IN PlayStation 4 Two fundamentally different methods of internet distribution have been implemented. The choice between them depends on your network infrastructure and goals:

Mode access points It is preferable - it is more stable and faster, because PS4 receives internet via a wired connection, not a wireless bridge. However, this requires the console to be physically connected to the router via a cable. LANIf this is not possible (for example, the router is in another room), the only mode left is bridge, but it has two critical drawbacks:

⚠️ Attention: In bridge mode PS4 Simultaneously connects to one Wi-Fi network and broadcasts another. This places additional strain on the console's processor and can lead to lag in games if more than two or three devices are connected to the access point.

Also, it is not possible to use in bridge mode 5 GHz - the console only works on the frequency 2.4 GHz, which increases the likelihood of interference from neighboring networks. If your router supports 5 GHz, it's better to extend the cable to PS4 and use it as an access point.

Step-by-step guide to setting up Wi-Fi sharing on PS4

To enable Internet sharing, follow these steps. Before we begin Make sure that:

Check your console's internet connection (via cable or Wi-Fi)

Disable all downloads and online games on your PS4

The charge of the devices you will connect is at least 50%

Remember the password for your primary Wi-Fi network (required for bridge mode)-->

Next, go to the console menu:

1. Open Settings → Network.

2. Select Setting up an Internet connection.

3. Click Use Wi-Fi (even if connected via cable).

4. Select Manual setup.

5. In the section IP Address Settings please indicate Automatically.

6. In the section DHCP Options select Do not specify.

7. In the section DNS settings select Automatically.

8. In the section Proxy server settings select Do not use.

9. Save your settings and return to the main menu Net.

10. Select Setting up an access point and follow the instructions on the screen.

After activating the access point PS4 will generate a network name (SSID) type PS4-XXXX and password. They can be changed manually, but remember:

• 🔐 The password must be at least 8 characters long and contain letters/numbers.
• 📡 Network name (SSID) must not contain spaces or special characters.

Limitations and typical problems

Despite the convenience, distributing Wi-Fi with PlayStation 4 has a number of limitations that you should know about in advance:

1. Speed ​​is limited to 72 Mbps even when connected via cable. This is due to hardware limitations of the chip. Broadcom BCM4356, which does not support modern standards 802.11ac or Wi-Fi 6.

2. Maximum 8 devices in access point mode and 5 in bridge mode. If the limit is exceeded, new connections will be blocked.

3. No IPv6 supportIf your ISP only uses IPv6, sharing won't work.

4. Problems with NATIn bridge mode PS4 creates Double NAT, which can block connection to some online games (for example, Call of Duty: Warzone or Fortnite).

Common mistakes and their solutions:

⚠️ Attention: If you use PS4 as a bridge for connection PS5 to the Internet, there may be problems with multiplayer games due to NAT Type 3In this case, it is better to connect PS5 directly to the router.

Impact on console performance

Sharing Wi-Fi puts additional strain on the processor. PS4, especially in bridge mode. Tests show that:

• 🎮 Games may crash FPS by 5–15% when connecting 3+ devices.
• 🔥 The console temperature increases by 3-7°C due to increased chip load Broadcom.
• 📥 Game download speed from PlayStation Store decreases by 20–30%.

Recommendations to minimize the impact:

• 🛑 Turn off the access point when it is not needed.
• 🔌 Use the mode access points (via cable) instead of a bridge.
• 🧹 Clear your console's cache regularly: Press and hold the power button for 7 seconds until you hear the second beep.

How to check CPU usage on PS4?

The console doesn't have built-in tools for monitoring CPU load, but it can be indirectly estimated by temperature. Install the app PS4 Remote Play On a PC and connect to the console—some versions display the temperature. Also, pay attention to the fan noise: if it's running at maximum speed without a load, this is a sign of overheating.

Alternatives: When It's Best Not to Use PS4 as a Hotspot

In some scenarios, Wi-Fi distribution with PlayStation 4 is unjustified or even harmful. Consider alternatives if:

• 🖥️ You need to connect desktop PC - it's better to use Powerline adapters or pull the cable.
• 📺 You are setting up Smart TV - modern televisions often conflict with Double NAT from PS4.
• 🎮 You are playing competitive shooters (For example, CS:GO or Valorant) - even minimal lags from Wi-Fi distribution can be critical.
• 🔄 You need to connect more than 3 devices - It's better to buy an inexpensive router (for example, TP-Link TL-WR840N).

If your goal is - Play on PC online from PS4, consider other options:

• 🔗 Direct cable connection (if the router supports IP Passthrough).
• 📡 Wi-Fi repeater (signal amplifier, for example, Xiaomi Wi-Fi Repeater 2).
• 🖧 Mobile hotspot (distribution from a phone, if the tariff allows).

Security: Risks and How to Avoid Them

Wi-Fi distribution with PlayStation 4 creates potential vulnerabilities in your network. The main risks are:

• 🔓 Weak default password — the console generates a simple 8-digit code that can be cracked using brute force.
• 🕵️ Lack of isolation of devices — connected gadgets see each other on the local network.
• 🚪 Firmware vulnerabilities — Sony rarely updates the network stack PS4, which makes it a target for attacks like KRACK.

How to protect yourself:

1. Change the access point password to a complex one (for example, P@ssw0rd_2026!PS4).

2. Turn off distribution when it is not needed (in the menu Settings → Network → Access Point Settings).

3. Do not connect to an access point PS4 devices with important data (for example, a work laptop).

4. Update your console firmware to the latest version (path: Settings → System Software → Update).

⚠️ Attention: If you use PS4 When using bridge mode to connect to a public Wi-Fi network (for example, in a cafe or hotel), all devices connected to your hotspot will see each other's traffic. This could lead to personal data leakage.

FAQ: Answers to frequently asked questions

Is it possible to share Wi-Fi from PS4 Slim and PS4 Pro at the same time?

No, each console can only operate in one sharing mode at a time. If you enable the access point on two PS4 on the same network, this will lead to an IP address conflict.

Why is the PS4's upload speed slower than my router's?

The console uses an outdated standard. 802.11n (max 72 Mbps), while modern routers support 802.11ac (up to 1 Gbps) or Wi-Fi 6 (up to 10 Gbps). In addition, the processor PS4 not optimized for traffic routing.

Can PS4 be used as a Wi-Fi repeater?

Technically yes, but only in bridged mode. However, this is inefficient: the console cannot automatically select the best channel and does not support roamingFor a more stable signal, it's best to buy a dedicated repeater.

Will the PS5 have better Wi-Fi than the PS4?

PlayStation 5 also supports Wi-Fi distribution, but uses a more modern chip Broadcom BCM4375 with support 802.11ac (up to 866 Mbps). However, there are limitations on the number of devices and problems with Double NAT remain.

How do I reset my access point settings on my PS4?

Go to Settings → Network → Access Point Settings and select DisableTo completely reset your settings, reset your console's network settings: Settings → Initialization → Restore default settings (does not delete games).
