Please select a model and download HotspotOS.
You have to match the exact AP / WiFi router version to prevent issues.
Connect your computer by network cable to the LAN port.
Please log in to the Asus web interface at https://192.168.1.1.
Go to the Administration / Firmware Upgrade page.
Click Choose File.
Navigate to the location where the HotspotOS for your model is downloaded and press on Open.
Press the Upload button.
The HotspotOS installation procedure can take a few minutes.
During this process, you will see information about the processing.
Reconnect LAN cable or Disable/Enable NIC card in order to get new valid IP address in 10.200.0.x range from router.
Start your browser and in URL field type https://10.200.0.1:8089/ to login to HotspotOS.
Press the Login button to access to Status tab.
On the HotSpotOS Status page, you can check AP MAC address, Public IP, device Uptime, Radius and Cloud status, and a number of users connected to AP.
The MAC address of your AP will be used in the SignUp process.
During SignUp, after typing HotSpot name, select as HotSpot model HotspotOS, and add your MAC address from the Status tab.
From the Setup page configure your AP.
The Hotspot is started and the Autostart and Inactivity Logout options are active by default.
Inactivity Logout is set to 900 sec. Inactivity period defines how long will the device stay logged-in without activity. This prevents repeated logins if connection temporarily breaks.
https redirect defines if https websites will be redirected to the splash page. Default and recommended is disabled, to prevent https browser certificate errors.
DNS Web Filtering – disabled
DNS Web Filter IP – 18.104.22.168
Auto Update – enabled
By default as Network WAN Connection is set DHCP, but you can choose network protocol based on your needs. Our recommendation is to use DHCP Network Protocol.
WiFi channels – Eleven channels are designated in the 2 GHz range, spaced 5 MHz apart from each other. Those eleven channels in the spectrum are allowed anywhere in the world.
DNS – Custom
IP – 10.200.0.1
From the SSID tab, you can Enable SSID 1 and 2.
Configure the SSID name and enable it.
Secondary SSID 2 is mostly used for staff WiFi with WPA2 password but you can also enable Hotspot on it.
You can also whitelist websites based on URL, IP, or MAC.
From the System tab, you can flash HotspotOS image and change Admin password.
Asus Lyra (MAP-AC2200)
Reset the router to factory defaults if it has been previously configured.
Installing HotspotOS on this device requires a two-step process, first writing the initramfs image from the OEM firmware – and then finalizing the installation by sysupgrading the real device firmware.
1 Enable ssh in the OEM firmware (use port 22).
2 Copy hotspotos-ipq40xx-generic-asus_map-ac2200-initramfs-fit-uImage.itb via scp to /tmp/
3 mtd-write -d linux -i /tmp/hotspotos-ipq40xx-generic-asus_map-ac2200-initramfs-fit-uImage.itb
4 reboot -f
5 Wait for it to reboot
6 Copy hotspotos-ipq40xx-generic-asus_map-ac2200-squashfs-sysupgrade.bin via scp to /tmp/
7 sysupgrade -n /tmp/hotspotos-ipq40xx-generic-asus_map-ac2200-squashfs-sysupgrade.bin
8 Wait for it to reboot
Asus windows recovery tool:
1 Download the ASUS Firmware Restoration Tool but don’t open it: https://dlcdnets.asus.com/pub/ASUS/wireless/4G-AC53U/Rescue_2102.zip
2 Unplug your computer from the router
3 Put the router into Rescue Mode by: turning the power off, using a pin to press and hold the reset button, then turning the router back on while keeping the reset button pressed for ~5 secs until the power LED starts flashing slowly (which indicates the router has entered Rescue Mode)
4 Important (if you don’t do this next step the Asus Firmware Restoration Tool will wrongly assume that the router is not in Rescue Mode and will refuse to flash it): go to the Windows Control Panel and temporarily disable ALL other network adapters except the one you will use to connect your computer to the router
5 For the single adapter you left enabled, temporarily give it the static IP 192.168.1.10 and the subnet mask 255.255.255.0
6 Connect a LAN cable between your computer (make sure to use the Ethernet port of the adapter you’ve just set up) and port 1 of the router (not the router’s WAN port)
7 Rename hotspotos-XX.XX.X-ramips-mt7620-rt-ac51u-squashfs-sysupgrade.bin to factory.trx
8 Open the Asus Firmware Restoration Tool, locate factory.trx and click upload (if Windows shows a compatibility prompt, confirm that the tool worked fine)
9 Flashing and reboot is finished when the power LED stops blinking and stays on
10 That’s it! (Don’t forget to re-enable any network adapters you disabled earlier)
1 Download the HotspotOS firmware image
2 Unplug the power cord from the router
3 Press the reset button with a pin and keep holding it down
4 Plug the power cord in
5 Wait 10 seconds
6 Release the reset button
7 On your computer, set a static IP to the network adapter connected to the router (IP 192.168.1.75, Subnet 255.255.255.0, connect to the first LAN port of the router)
8 Use tftp -client to download the firmware image
tftp> put hotspotos-XX.XX.X-ramips-mt7620-rt-ac51u-squashfs-sysupgrade.bin
9 The power LED flashes quickly while the router is being flashed
10 Flashing is successful when the power LED is constantly lit
Update using ASUS Firmware Restoration Tool:
