AVM FRITZ!

Please select a model and download HotspotOS.
You have to match the exact AP / WiFi router version to prevent issues.

Connecting

Please reset the AP / WiFi router to factory settings to avoid problems with some previous configuration.

Connect your computer to the AVM FRITZ! router web interface.
Go to the Firmware upgrade section.

IMPORTANT

Be sure and untick Keep settings option before HotspotOS installation.


Navigate to the location where the HotspotOS for your model is downloaded and press Open.
Press the Firmware Update button.
Click Upload to complete the HotspotOS installation.

The HotspotOS installation procedure can take a few minutes.

During this process, you will see information about the processing.

Do not power off the router during the HotspotOS installation, as it can cause the device to crash or become unusable.

Reconnect LAN cable or Disable/Enable NIC card in order to get new valid IP address in 10.200.0.x range from router.

Configuring parameters

Start your browser and in the URL field type https://10.200.0.1:8089/ to login to HotspotOS.

Username: admin
Password: admin

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 – 13.92.228.228
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

Please note, if the DNS IP address isn’t 10.200.0.1 the whitelist will have no effect.

Save changes.

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.


If you want to use Social network login feature or Paypal as payment gateway, enable it on the Whitelist tab and Save changes.

You can also whitelist websites based on URL, IP, or MAC.

From the System tab, you can flash HotspotOS image and change Admin password.

When you finish setup, restart the AP / WiFi router to apply changes.

AVM FRITZ! HotspotOS Download

AVM FRITZ!Box 4020

Download HotspotOS

Flash Instructions

Installation via EVA:
In the first seconds after power is connected, the bootloader will listen for FTP connections on 169.254.157.1 (Might also be 192.168.178.1).
Firmware can be uploaded like following:

ftp> quote USER adam2
ftp> quote PASS adam2
ftp> binary
ftp> debug
ftp> passive
ftp> quote MEDIA FLSH
ftp> put hotspotos-ath79-generic-avm_fritz4020-squashfs-sysupgrade.bin mtd1

Note that this procedure might take up to two minutes. After transfer is complete you need to powercycle the device to boot HotspotOS.

Download sysupgrade HotspotOS

Flash Instructions

1. Grab the uboot for the Device from the ‘u-boot-fritz1200’ subdirectory. Place it in the same directory as the ‘eva_ramboot.py’ script. It is located in the ‘scripts/flashing’ subdirectory.

2. Assign yourself the IP address 192.168.178.10/24. Connect your Computer to one of the boxes LAN ports.

3. Connect Power to the Box. As soon as the LAN port of your computer shows link, load the U-Boot to the box using the following command.

> ./eva_ramboot.py –offset 0x85000000 192.168.178.1 uboot-fritz1200.bin

4. The U-Boot will now start. Now assign yourself the IP address 192.168.1.70/24. Copy the HotspotOS initramfsimage to a TFTP server root directory and rename it to ‘FRITZ1200.bin’.

5. The Box will now boot HotspotOS from RAM. This can take up to two minutes.

6. Copy the U-Boot and the HotspotOS sysupgrade (!) image to the Box using scp. SSH into the Box and first write the Bootloader to both previous kernel partitions.

> mtd write /path/to/uboot-fritz1200.bin uboot0
> mtd write /path/to/uboot-fritz1200.bin uboot1

7. Remove the AVM filesystem partitions to make room for our kernel + rootfs + overlayfs.

> ubirmvol /dev/ubi0 –name=avm_filesys_0
> ubirmvol /dev/ubi0 –name=avm_filesys_1

8. Flash HotspotOS peristently using sysupgrade.

> sysupgrade -n /path/to/hotspotos-sysupgrade.bin

Flash Instructions

FRITZ!Box typically uses 192.168.178.1 as the default IP in the bootloader. If the device doesn’t respond, try with 192.168.1.1.

Assign a static IP in the 192.168.178.x range (e.g. 192.168.178.100) to your PC (192.168.1.x if the device uses 192.168.1.1 as its default IP).
Ideally, place a switch in between the router and your client (this slightly widens your FTP flashing window).
Power on your device and use scripts/flashing/eva_ramboot.py to send initramfs-kernel.bin to the router. The router will then boot into HotspotOS: python3 /path/to/eva_ramboot.py 192.168.178.1 /path/to/hotspotos-lantiq-xrx200-avm_fritz7362sl-initramfs-kernel.bin
Blinking red power LED indicates that HotspotOS is running in recovery mode.
Set an IP address in 192.168.1.x range on your PC, or enable DHCP.
Transfer the sysupgrade image to the /tmp directory of the router using scp and run sysupgrade.

First boot might take a bit longer if linux_fs_start was set to 1. In that case the device will reboot twice, first time it will fail to load second kernel (overwritten by ubifs), set linux_fs_start to 0 and reboot.

Installation via FTP:
1. Use scripts/flashing/eva_ramboot.py to send initramfs-kernel.bin to the device when powering on.
Standard AVM procedures with finding the correct IP address and the right moment to open FTP apply here (approx. 4 seconds on 7362SL).
IMPORTANT: set lzma compression in ramdisk options, bootloader stalls when receiving uncompressed images.

2. Transfer sysupgrade.bin image with scp to /tmp directory and run sysupgrade

3. First boot might take a bit longer if linux_fs_start was set to 1, in that case the device will reboot twice, first time it will fail to load second kernel (overwritten by ubifs), set linux_fs_start to 0 and reboot.

HotspotOS uses the entire NAND flash. Kernel uses 4 MiB and rootfs uses the rest of 124 MiB, overwriting everything related to FRITZ!OS – both OS images, config and answering machine/media server data. To return to FRITZ!OS, use AVM’s recovery image.


AVM FRITZ!Box 7412

Download initframs HotspotOS
Download sysupgrade HotspotOS

Flash Instructions

Use the eva_ramboot.py script to load an initramfs image on the device. Run it a few seconds after turning the device on.
$ scripts/flashing eva_ramboot 192.168.178.1 bin/targets/lantiq/xrx200/openwrt-lantiq-xrx200-avm_fritz7412-initramfs-kernel.bin
If it fails to find the device try the ip address 169.254.120.1.
(Firmware updates or the recovery tool apparently change it.)

IMPORTANT: set lzma compression in ramdisk options, bootloader stalls when receiving uncompressed images.

The device will load it in ram and boot it. You can reach it under the openwrt default ip address 192.168.1.1.

Check if the key linux_fs_start is not set to 1 in tffs:
$ fritz_tffs_nand -d /dev/mtd1 -n linux_fs_start
If it is set to 1, the bootloader will select the wrong set of partitions. Restart the box and install an FritzOS upgrade or do a recovery. Afterwards start again at step 1.

Run sysupgrade to persistently install HotspotOS.
