TL;DR
- AOSS (AirStation One-Touch Secure System) is a Buffalo Technology feature that lets you connect devices to Wi-Fi with one button press — no password needed (NCESC, 2024).
- The AOSS button is on your router, not on the PS4 console itself (Coop La Lonja, 2021).
- AOSS is similar to WPS but developed by Buffalo — both allow easy wireless setup (Buffalo, 2025).
- PS4 supports AOSS setup through Settings > Network > Set Up Internet Connection > Use Wi-Fi > Easy > AOSS (Buffalo, 2025).
- AOSS is only available in certain countries and regions — check your router compatibility first (PlayStation Support, 2026).
- If AOSS isn’t available, you can manually connect by selecting your Wi-Fi network (SSID) and entering the password (PlayStation Support, 2026).
What Is AOSS and How Does It Work?
AOSS stands for AirStation One-Touch Secure System. It is a wireless setup protocol developed by Buffalo Technology that simplifies the process of connecting devices to a Wi-Fi network (NCESC, 2024). Instead of manually searching for your network name (SSID) and typing in a long password, AOSS allows you to connect with a single button press on your router (Coop La Lonja, 2021).
Here’s how it works: when you press the AOSS button on your router, the router enters a discovery mode and starts searching for nearby devices that are also looking for an AOSS connection. On your PS4, when you select the AOSS setup option, it begins broadcasting a signal that the router can detect. Within a short window (usually about two minutes), the two devices find each other and automatically exchange the security information needed to establish a secure connection (Coop La Lonja, 2021). Once connected, the router’s LED indicator stops flashing to confirm the connection is established (Buffalo, 2025).
The key advantage is convenience — you don’t need to know your network name or password. This is especially helpful if you’ve changed your Wi-Fi password and don’t remember it, or if you’re setting up a new device in a hurry.
Where Is the AOSS Button Located?
The AOSS button is not on your PS4. It is located on your wireless router (Coop La Lonja, 2021). The exact location varies by router model, but it is typically found on the back, front, or side panel of the router (NCESC, 2024). On Buffalo AirStation routers, the button is usually clearly labeled “AOSS” (Buffalo, 2025).
If you can’t find the AOSS button on your router, check the user manual that came with your router or look for a button labeled “WPS” instead — many modern routers support both protocols, and the WPS button can often be used in place of AOSS (Buffalo, 2025).
AOSS vs WPS: What’s the Difference?
AOSS and WPS (Wi-Fi Protected Setup) serve the same basic purpose: making wireless connections easier. However, there are some key differences.
AOSS (AirStation One-Touch Secure System) was developed by Buffalo Technology specifically for Buffalo routers and devices (NCESC, 2024). It is a proprietary protocol that works primarily with Buffalo hardware, though some other manufacturers have licensed it (Coop La Lonja, 2021).
WPS (Wi-Fi Protected Setup) is an industry-standard protocol developed by the Wi-Fi Alliance. It is supported by virtually all modern routers from all manufacturers (PlayStation Support, 2026). WPS offers several connection methods: the Push Button method (similar to AOSS), PIN entry, and NFC.
On PS4: Both AOSS and WPS are supported. When you go to Settings > Network > Set Up Internet Connection > Use Wi-Fi > Easy, the PS4 will display both “Set Up Using AOSS” and “Set Up Using WPS Button” as options if your router supports them (Buffalo, 2025; PlayStation Support, 2026).
Important note: AOSS is only available in certain countries and regions (PlayStation Support, 2026). If AOSS doesn’t appear as an option on your PS4, your region may not support it, or your router may not be AOSS-compatible.
How to Connect Your PS4 to Wi-Fi Using AOSS
Follow these step-by-step instructions to connect your PS4 to your wireless network using AOSS (Buffalo, 2025; Coop La Lonja, 2021):
Step 1: Make sure your Wi-Fi router is powered on and other devices (like your computer or smartphone) can connect to it successfully (Buffalo, 2025).
Step 2: On your PS4, navigate to the home screen and select Settings (the toolbox icon).
Step 3: Select Network from the Settings menu.
Step 4: Select Set Up Internet Connection (Buffalo, 2025).
Step 5: Select Use Wi-Fi for a wireless connection.
Step 6: Select Easy as the setup method (Buffalo, 2025).
Step 7: Select Set Up Using AOSS from the available options (Buffalo, 2025).
Step 8: On your router, locate and press the AOSS button. Hold it down until the AOSS indicator light starts flashing (Buffalo, 2025). This usually takes about 2-3 seconds.
Step 9: Release the button once the light starts flashing. Your router is now in discovery mode and will search for AOSS-compatible devices for about two minutes (NCESC, 2024).
Step 10: Wait for the PS4 to detect the router and establish the connection. The router’s LED will stop flashing when the connection is successful (Buffalo, 2025).
Step 11: Once the connection is complete, select Test Internet Connection to verify your PS4 is online (Buffalo, 2025).
Step 12: If the test shows “IP Address” and “Internet Connection” as “Successful,” your setup is complete (Buffalo, 2025).
How to Connect Your PS4 to Wi-Fi Using WPS Button
If your router doesn’t have an AOSS button but has a WPS button, you can use the same process (PlayStation Support, 2026):
Step 1: On your PS4, go to Settings > Network > Set Up Internet Connection > Use Wi-Fi > Easy (PlayStation Support, 2026).
Step 2: Select Set Up Using WPS Button (PlayStation Support, 2026).
Step 3: Press the WPS button on your router within two minutes (NCESC, 2024).
Step 4: Wait for the connection to complete and test your internet connection (PlayStation Support, 2026).
How to Connect PS4 to Wi-Fi Manually (Without AOSS or WPS)
If your router doesn’t support AOSS or WPS, or if you prefer to enter your network details manually, you can connect using the manual method (PlayStation Support, 2026):
Step 1: On your PS4, go to Settings > Network > Set Up Internet Connection > Use Wi-Fi (PlayStation Support, 2026).
Step 2: Select Easy (PlayStation Support, 2026).
Step 3: A list of available Wi-Fi networks will appear. Find your network name (SSID) and select it (PlayStation Support, 2026; Belkin, 2024).
Step 4: If your network is password-protected (indicated by a padlock icon), enter your Wi-Fi password using the on-screen keyboard and select Connect (PlayStation Support, 2026).
Step 5: Wait for the connection to complete and test your internet connection.
Tip: The PS4 only supports 2.4 GHz Wi-Fi networks — it does not support 5 GHz networks (Belkin, 2024). Make sure you’re connecting to a 2.4 GHz network.
How to Connect Your PS4 to the Internet with Your Phone (Mobile Hotspot)
If you don’t have access to a traditional Wi-Fi network, you can connect your PS4 to the internet using your phone’s mobile hotspot (SneakyWiFi, 2025):
Step 1: On your smartphone, enable the Personal Hotspot or Mobile Hotspot feature (SneakyWiFi, 2025):
- iPhone: Settings > Personal Hotspot > toggle on
- Android: Settings > Network & Internet > Hotspot & tethering > toggle on (Alvaro Trigo, 2023)
Step 2: Note the hotspot name and password displayed on your phone.
Step 3: On your PS4, go to Settings > Network > Set Up Internet Connection > Use Wi-Fi (SneakyWiFi, 2025).
Step 4: Select your phone’s hotspot from the list of available networks (SneakyWiFi, 2025).
Step 5: Enter the hotspot password and select Connect.
Step 6: Your PS4 will test the connection and connect to the internet via your phone’s data plan (SneakyWiFi, 2025).
Important considerations:
- Mobile hotspot connections consume your phone’s data plan
- Connection speed depends on your cellular network (4G/5G) and signal strength
- Walls and obstacles can interfere with the signal between your PS4 and mobile hotspot (NCESC, 2024)
Troubleshooting: PS4 Won’t Connect to Wi-Fi but Everything Else Does
This is one of the most common PS4 network issues. If other devices can connect to your Wi-Fi but your PS4 cannot, try these fixes (SlashGear, 2023):
1. Verify your Wi-Fi password. Make sure you’ve entered the correct password in the PS4’s settings — even a single mistyped character will prevent connection (SlashGear, 2023).
2. Move the PS4 closer to the router. Physical distance and obstructions (walls, furniture, electronics) can weaken the signal (SlashGear, 2023; PlayStation Support, 2024).
3. Power cycle your router. Turn off your router and/or modem, wait five minutes, then restart them (PlayStation Support, 2026). This clears temporary network issues.
4. Test your internet connection. On your PS4, go to Settings > Network > Test Internet Connection to identify where the connection is failing (PlayStation Support, 2024).
5. Reduce network congestion. Other devices on your network might be using a large amount of bandwidth. Wait until they’re finished (PlayStation Support, 2026).
6. Update your router’s firmware. Outdated router firmware can cause compatibility issues (PlayStation Support, 2026).
7. Change your router’s Wi-Fi channel. Interference from neighboring networks can cause connection problems. Change your router’s Wi-Fi channel in the router settings (Windows Report, 2024).
8. Try a wired connection. If wireless continues to fail, use an Ethernet cable for a stable connection (PlayStation Support, 2026).
DHCP Host Name on PS4: What Is It?
When you set up your PS4 connection manually, you may encounter the DHCP Host Name setting. This is an optional field that some network administrators use to identify devices on a network.
What to do: In most home network setups, you should select Do Not Specify for DHCP Host Name (Cloudflare, 2026; AdGuard DNS, 2024). This is the recommended setting for standard PS4 network configurations.
When setting up a custom connection:
- Go to Settings > Network > Set Up Internet Connection
- Select either Use Wi-Fi or Use a LAN Cable
- Select Custom instead of Easy (Cloudflare, 2026)
- Set IP Address Settings to Automatic (Cloudflare, 2026)
- Change DHCP Host Name to Do Not Specify (Cloudflare, 2026)
- Set DNS Settings to Manual if you want to use custom DNS (like Google’s 8.8.8.8) (Cloudflare, 2026)
