📶 WIFI DONGLE COMPATIBILITY

R36S has no built-in WiFi. You can use WiFi dongle with USB OTG adapter.

WANT BUILT-IN WIFI?

You can add internal WiFi to your R36S with a hardware modification. This eliminates the need for external dongles and OTG adapters.

📋 Requirements

1
USB WiFi Adapter

RTL8188FTV or MT7601 based adapter recommended (see compatibility table above)

2
USB-C to USB-A OTG Adapter

Required to connect the WiFi dongle to R36S USB-C port

3
Updated ArkOS

Make sure you're running the latest ArkOS version

⚠️ Important Notes
  • Avoid "WiFi 6" or "Free Driver" adapters - they won't work
  • Most 5GHz WiFi adapters are NOT supported - use 2.4GHz. Exception: RTL8821AU-based adapters (e.g. TP-Link T2U Plus) work with 5GHz
  • Left USB-C port is charging only - use right port for OTG
  • Low battery may cause WiFi connection issues

🔧 Driver Installation

If your WiFi adapter requires drivers (RTL8188FTV/MT7601), follow these steps:

1

Download driver from: RTL8188FTV-MT7601 Driver

2

Extract and copy driver files to Ports folder on your SD card

3

On R36S: Navigate to Ports → Select "Install Driver" → Choose your adapter model → Confirm "Yes"

4

Device will reboot automatically after installation

📡 Connecting to WiFi

1

Plug WiFi adapter into OTG adapter, then connect to R36S right USB-C port

2

Go to: Options → WIFI (or RetroPie → WIFI)

3

Select "Connect to new WiFi Connection"

4

Wait for network scan (10-20 seconds)

5

Select your network, enter password, and connect

🔍 Troubleshooting

❌ No Networks Showing (Empty List)
  • Unplug and replug the WiFi adapter
  • Reboot R36S with adapter plugged in
  • Try a different OTG adapter
  • Test WiFi adapter on a PC to verify it works
🔊 Speaker Crackling Noise (R36S Only)

This is a hardware design issue caused by poor power filtering near the audio circuit. R36H has much less noise.

  • Use R36H instead (best solution)
  • Try different WiFi adapters
  • Use headphones
  • Don't use WiFi while charger is plugged in
🔋 Low Battery WiFi Issues

WiFi adapter needs stable 5V power. When battery is low, the internal step-up converter can't provide enough power.

Solution: Keep device plugged into charger while using WiFi
