Video walkthrough: youtu.be/-0Kuwm56mB8 (About 4 minutes - stock Ruijie firmware, then OpenWrt, then AJKFi.)

1. Flash AJKFi

Easiest way: one installer file and about 10 minutes. Or the 2-step way: plain OpenWrt first, then AJKFi. All files are in your model's own Drive folder.

Option A - Direct installer (both models, about 10 minutes)

One file. The router downloads the newest AJKFi from the internet and installs it by itself. Take the installer made for your own model.

1. Plug in the internet first
   Connect the router's WAN port to a working internet line (your modem or main router). Connect your PC to a LAN port with a cable.
2. Upload the installer
   In the Ruijie page: System → Upgrade → Local Upgrade → uncheck Keep Config → Browse → choose the installer for your model (AJKFi-Installer-EW1200G-PRO.bin or AJKFi-Installer-EW1300G.bin) → Upload.
3. Wait about 10 minutes
   The router restarts, downloads the newest AJKFi, checks it and installs it by itself, then restarts once more. Do not unplug the power or the internet cable. To watch it, open http://192.168.1.1 - the AJKFi installer page shows what it is doing.
4. Done
   Join the Wi-Fi AJK PISOWIFI and open http://10.0.0.1:8080. Carry on with 02 Activate.
5. Same message for more than 15 minutes?
   Read it - it says what is wrong (most often: no internet on the WAN port). To finish by hand, press the OpenWrt page link on the installer page (user root, no password) and do step 2 of Option B with the AJKFi file.

Option B - 2-step: plain OpenWrt, then AJKFi (both models)

1. Flash plain OpenWrt
   Upload the above OpenWrt firmware in the Ruijie page: System → Upgrade → Local Upgrade → uncheck Keep Config → Browse → Upload. When it restarts, open http://192.168.1.1 - the Status page must name your exact model.

   

2. Flash AJKFi
   In OpenWrt: System → Backup / Flash Firmware → Flash new firmware image. Choose the AJKFi file for your model, untick Keep settings, and flash. The router comes back on http://10.0.0.1:8080.

2. Activate

1. Plug in the internet
   Put your internet cable into the router's WAN socket. The router needs to reach us once to collect its licence.
2. Open the admin page
   Connect to the Wi-Fi called AJK PISOWIFI, then open http://10.0.0.1:8080. Sign in with admin / admin.
3. Activate
   Open System. If you sent us your Account ID when you bought, press Check In Now and the licence arrives by itself. If you were given a licence code, type it in instead. The page shows Licensed when it is done.

3. Set the admin password

1. Change admin / admin
   Go to Settings → Admin Account and set your own password. Anyone connected to your Wi-Fi can reach this login page, so do it before the machine goes out.
2. Put the dashboard on your phone
   Open http://10.0.0.1:8080 on your phone. Android (Chrome): menu ⋮ → Add to Home screen. iPhone (Safari): Share → Add to Home Screen. It gets the AJKFi icon and opens straight to the Dashboard.
3. Open it from anywhere (Cloud Remote)
   Sign in at ajkfi.com, open My machines and press Remote - the dashboard opens already signed in, from anywhere with internet (AJKFi 3.55 or newer, Lite 1.4 or newer). Give the machine a name there with Rename. Remote can be switched off on the router under Network → Cloud Remote.

4. Name your Wi-Fi

1. Name your customer Wi-Fi
   Network → Wireless. Rename AJK PISOWIFI to your shop name. Leave it open - customers pay at the portal, not with a password. Name it before you open: the name cannot be changed while a customer with running time is connected.
2. Add a hidden Wi-Fi for the coin slot
   On the same page, under Add Another SSID, add a second SSID on the 2.4 GHz radio, tick Hidden, and give it a password - required, the coin slot will not join a Wi-Fi without one. 2.4 GHz matters: the coin slot board cannot see 5 GHz.

5. Connect the coin slot

1. Flash the board
   Easiest: open ajkfi.com/flash (the ESP8266 Online Flasher) in Chrome or Edge on a computer, plug the board in with a USB data cable and press Connect and flash - choose New board for a new one, Update for one already in service (it stays paired with the router). Or use PyFlasher or NodeMCU Flasher: 115200, DIO, erase yes on a new board, no when updating. From coin slot 2.5 on, later updates come from the router: Settings → Coinslot Hardware → Update coin slot.
2. Pair it with the router
   On the router tap Pair coin slot in Settings → Coinslot Hardware, then power the board. A coin slot 2.9 or newer finds the router by itself: within about a minute the router shows Paired - no phone, nothing to type. Then set the lock to Active HIGH in Settings → Coinslot Hardware → Coin acceptor wiring and tap Save to coin slot. Older board, or two machines pairing at the same time: join the board's own Wi-Fi AJKFi-Coinslot-Setup from a phone, pick the coin slot Wi-Fi, type its password, set the lock mode to Active HIGH and press Save & connect.
3. Wire it
   Three wires from the coin acceptor to the ESP8266 board: COIN to D6, SET (the lock wire) to D7, and GND to GND. The ground wire is not optional - without it the coin slot counts coins that were never inserted. The 12 V adapter runs the acceptor and the board together through the base board's DC socket.

   

4. Test it and put it in the box
   Insert a real coin through the portal and watch it appear. Then drop a coin without tapping INSERT COIN: it must come back out - if it is taken, switch the lock the other way in Settings → Coinslot Hardware → Coin acceptor wiring on the router and tap Save to coin slot (coin slot 2.4 + AJKFi 3.45 or newer; older boards: on the board's setup page, hold its FLASH button 3 seconds). If coins go in but no time is credited, try the coin signal (D6) setting there the other way. The wires do not change. Then mount everything in the box and test one more coin. Swapping in a new board later: tap Pair new coin slot in Settings → Coinslot Hardware first.

6. Going back to Ruijie firmware

Video walkthrough: youtu.be/MGaeEF3qidY (1 minute 30 seconds, spoken in Tagalog - from the AJKFi admin page back to the Ruijie page.)

1. Both Ruijie models can go back
   We hold a stock image for the RG-EW1200G PRO v1.1 (ReyeeOS 1.219.1821) and the RG-EW1300G v1 (ReyeeOS 1.303.1422), each read off a real unit. The router only lists the image made for its own board, so it cannot pick the wrong one.
2. Save your sales first
   Going back to Ruijie firmware erases the machine completely - settings, sales, everything. System → Firmware offers a backup; take it and keep it somewhere safe before you go on.
3. Put the router online
   The router fetches the Ruijie image from us itself, so it needs a working internet connection on its WAN socket. There is no file for you to download and no file to upload.
4. Find the image
   System → Firmware → Check for Firmware. Under Return to stock firmware you will see Ruijie stock. Choose it and press Download & Check Selected - the router downloads the image and checks it. If nothing appears, the router has no internet.
5. Flash it
   When every check has passed, read the warning, type FLASH, press Flash Selected Firmware and then OK. Do not switch it off. After about 3 minutes the router comes back as a factory-fresh Ruijie, so it is no longer on 10.0.0.1:8080. Open 192.168.110.1 (the Ruijie default address) and set it up like a new Ruijie.
6. Coming back to AJKFi later
   Option A (the installer) or Option B (plain OpenWrt, then AJKFi), exactly as in step 01 above. Your licence still works - it is tied to the router's address, which none of this changes.
