How to Ensure Successful WiFi Connection on Players (SU3 / SU5 / SU7 / SU9)

Before you start:

• Make sure your SU player's system time and date are correct (incorrect time can cause authentication failures).
• Keep the player within 2–5 meters of your WiFi router during initial setup.
• Know your WiFi password (case-sensitive).

Supported WiFi standards:

• SU series supports dual-band WiFi: 2.4 GHz (802.11 b/g/n) and 5 GHz (802.11 a/n/ac).
• Security modes: WEP, WPA, WPA2 (Personal), WPA3 (if supported by firmware; check your device).
• Both hidden SSID and broadcast SSID are supported.

Step-by-step connection:

1. Go to Settings → Network & Internet → WiFi.
2. Toggle WiFi ON and wait for the scan to complete (5–10 seconds).
3. Select your network from the list. Networks may show frequency bands (2.4G or 5G) if available.
4. Enter the password carefully (use "Show password" if needed).
5. Tap "Connect". Wait for the status to change to "Connected".

Critical checks for successful connection:

• Not outdoor/public WiFi with captive portal – Public hotspots often require a web login. SU players cannot handle captive portals.
• No MAC address filtering (unless whitelisted) – If your router has MAC filtering enabled, add the SU player's MAC address to the allow list. Find MAC address in Settings → About → Status.
• DHCP enabled – The player must obtain an IP address automatically via DHCP. Static IP is possible via advanced settings (Modify network → Advanced → Static IP).
• Compatible band – 2.4 GHz is recommended for longer range; 5 GHz offers faster speed but shorter range. Make sure your router broadcasts the band you intend to use.
• Channel selection – For 5 GHz, avoid DFS channels (52–144) if your player has poor detection – use non-DFS channels like 36–48 or 149–165.

Troubleshooting when connection fails:

Network not visible?

• Ensure the router's SSID is not hidden (hidden networks are supported, but you must manually add them via "Add network").
• If using 5 GHz, move the player closer to the router (5 GHz has shorter range).
• Reboot the router and the SU player.

"Authentication error" (wrong password)?

• Double-check password case sensitivity.
• Try removing special characters from the password temporarily (some devices have issues with $, &, #).

"Failed to obtain IP address"?

• Log into your router and ensure DHCP server is enabled.
• Increase the DHCP address pool or reduce lease time.
• Reboot both devices.

Connected but no internet?

• Check if the router requires a captive portal login. SU players cannot use such networks.
• Verify that your internet connection is active on other devices.

Connection drops frequently?

• For 2.4 GHz: interference from microwaves, cordless phones, or neighboring routers. Change channel to 1, 6, or 11.
• For 5 GHz: DFS channels can cause drops when radar signals are detected. Switch to non-DFS channels (e.g., 36, 40, 44, 48, 149, 153, 157, 161).
• Update the SU player's firmware.

Advanced tips for technical users:

• Preferred band selection: In Developer Options (enable by tapping Build Number 7 times), you can set "WiFi Frequency Band" to 2.4 GHz only, 5 GHz only, or auto. This helps when both bands share the same SSID.
• Static IP: Modify network → Advanced → Static IP (useful if DHCP is unreliable).
• WiFi power saving: In Developer Options, disable "WiFi power saving" for more stable streaming (slightly higher battery drain).
• Check router logs: Look for "deauth", "association timeout", or "DHCP failure" entries.

Pro tip: If you travel with your SU player, create a mobile hotspot from your phone (5 GHz capable phones will provide 5 GHz hotspot). Test connection there to isolate player issues from router issues.
