R36S Wi-Fi Setup Guide

Does the R36S Have Built-In Wi-Fi?

This is one of the most common questions from new R36S owners, and the answer depends on which model you have.

• Standard R36S: NO built-in Wi-Fi. This is by design and not a defect.
• R36S Plus (2025 model): YES, built-in Wi-Fi. This is one of the key hardware upgrades over the standard model.
• R36XX variant: YES, built-in Wi-Fi.

If you have a standard R36S, you need an external USB Wi-Fi dongle to get online. The absence of Wi-Fi is not a malfunction — it is simply a cost-cutting decision in the original design.

What You Need for Wi-Fi on Standard R36S

Getting Wi-Fi working on the standard R36S requires two inexpensive accessories:

• A compatible USB Wi-Fi dongle — the chipset inside the dongle determines whether it will work with ArkOS or Rocknix. Not all dongles are compatible (see the next section).
• A USB-A to USB-C OTG adapter — the R36S has a USB-C port, but most cheap Wi-Fi dongles use a USB-A connector. An OTG (On-The-Go) adapter bridges the two.
• Alternative: A USB-C Wi-Fi dongle avoids the need for an OTG adapter entirely, though these are less common and slightly more expensive.

Total cost for both items combined is approximately €5–10, making this one of the cheapest hardware upgrades you can make for the R36S.

Compatible Wi-Fi Dongles for R36S

The key thing to understand is that the chipset inside the dongle — not the brand name printed on the box — determines compatibility. ArkOS and Rocknix include kernel drivers for specific chipsets. If your dongle uses a chipset without a driver, it will not work.

Recommended Chipsets (ArkOS/Rocknix Compatible)

• Realtek RTL8188EUS — the most widely used chipset for R36S Wi-Fi. Excellent ArkOS and Rocknix support. Very cheap and widely available.
• Realtek RTL8192CU — good compatibility across both firmware options.
• Realtek RTL8812BU (AC1200 dual-band) — works, though setup can be slightly more complex than the simpler Realtek chipsets.
• MediaTek MT7601U — good compatibility and often the cheapest option available.

What to Avoid

• Ralink/MediaTek chipsets newer than MT7601 — driver support is inconsistent and frequently causes recognition failures.
• Dongles requiring Windows-only driver installation software — these almost certainly use chipsets with no Linux kernel driver.
• USB 3.0 dongles — USB 2.0 is fine and generally more compatible with the R36S OTG port.

Recommended Products to Search For

• "Mini USB Wi-Fi adapter RTL8188" — tiny, cheap, and widely available on AliExpress and Amazon. This search reliably returns compatible hardware.
• "150Mbps USB wireless adapter" — these are almost always RTL8188-based and work well.
• Avoid purchasing well-known brand-name dongles from TP-Link, ASUS, or Netgear — these manufacturers frequently switch to newer chipsets with poor Linux driver support.

How to Connect the Dongle

Physical Connection

1. Get your USB-A to USB-C OTG adapter.
2. Plug the Wi-Fi dongle into the USB-A end of the OTG adapter.
3. Plug the USB-C end into the R36S charging and data port (the bottom port).
4. Power on the R36S, or reboot the device if it is already running. The dongle needs to be connected at boot for most firmware versions to recognise it.

Configuring Wi-Fi in ArkOS

1. From the EmulationStation main menu, press the Start button.
2. Navigate to Network Settings.
3. Set the Enable Wi-Fi toggle to ON.
4. Select SSID and choose your network name from the list that appears.
5. Enter your Wi-Fi password using the on-screen keyboard.
6. Select Connect and wait 10–20 seconds.
7. When an IP address appears in the network settings screen, the connection was successful.

Configuring Wi-Fi in Rocknix

1. From the EmulationStation main menu, press the Start button.
2. Navigate to Network Settings and select Enable Network.
3. Set your Wi-Fi SSID and enter your password.
4. Save the settings. The device will connect automatically on next reboot.

What Wi-Fi Enables on R36S

Once you have Wi-Fi working, several useful features become available that are not accessible offline.

RetroAchievements

RetroAchievements lets you earn achievement points for retro games while playing on R36S, similar to Xbox Achievements or PlayStation Trophies but for classic games.

• Setup: Go to RetroArch → Settings → Achievements, then enable Hardcore or Softcore Mode.
• Enter your RetroAchievements.org account credentials (create a free account at retroachievements.org).
• Compatible systems include NES, SNES, GBA, Sega Genesis, PS1, and many more.
• Achievements unlock in real-time as you play, with on-screen notifications.

PortMaster (Game Downloads)

PortMaster is a game port manager built into ArkOS and Rocknix. With Wi-Fi active, it allows you to browse and install free game ports directly on the device with no PC required.

• All downloads happen on-device over your Wi-Fi connection.
• Popular ports available include Quake, Cave Story, OpenBOR, Diablo (DevilutionX), DOOM, and over 200 more.
• Some ports require you to provide original game data files; others are completely free and self-contained.

Samba File Sharing (Add Games Wirelessly)

With Wi-Fi active, ArkOS automatically enables a Samba network share, making it possible to add ROM files to the R36S from your PC without removing any SD cards.

• On your PC: open File Explorer and navigate to Network. The R36S device should appear automatically.
• Drag and drop ROM files directly into the appropriate folder on the device.
• This is significantly more convenient than repeatedly removing and reinserting the SD card, especially for large ROM collections.

Online Multiplayer (Netplay)

RetroArch Netplay enables online multiplayer for supported emulators over your Wi-Fi connection.

• Works best with NES, SNES, GBA, and Sega Genesis games, which have low latency requirements that Wi-Fi can generally meet.
• To host or join a session, go to RetroArch → Netplay → Host or Connect to Network Session.
• Performance depends heavily on your network conditions and the latency between both players.

Troubleshooting Wi-Fi Issues

Dongle Not Recognized

• Reboot the R36S with the dongle already connected — do not hot-plug it after boot.
• Try a different OTG adapter. Some OTG adapters are charge-only and do not pass data signals. If the adapter feels very flimsy or came bundled with a cheap cable, replace it.
• Confirm the dongle uses a supported chipset. Check the product listing for chipset information.
• Check your ArkOS version: very old firmware versions may include fewer Wi-Fi drivers. Updating ArkOS may add support for your chipset.

Wi-Fi Stopped Working After July 2025 ArkOS Update

A known bug was introduced in the ArkOS update released in July 2025 that caused OTG Wi-Fi dongles to stop connecting, even on hardware that had previously worked correctly.

• Workaround: Downgrade to the previous stable ArkOS release.
• Alternatively, check the ArkOS GitHub Issues page for the latest fix patch or hotfix release addressing this specific regression.

Poor Signal or Frequent Drops

• The R36S OTG port was not designed with continuous Wi-Fi use in mind. The connection can be less stable than a dedicated Wi-Fi chip soldered to the motherboard.
• Move closer to your router for the initial setup and for any large file transfers.
• For transferring large ROM collections, a direct USB cable connection to your PC is more reliable and significantly faster than Wi-Fi Samba transfers.
