This page is currently under construction. You can edit the article to help completing it. Write a short, relevant description of the device. Include a technical overview, but avoid marketing buzzwords/useless stuff. Two to four sentences is about right. A picture is good, too. Edit the page to see how to add pictures. Any text with a light background (like this one) provides instructions for creating the Details Page. When you have filled in correct/useful information (instead of any template that's there) remove the instructions, as well as the <WRAP> that encloses it. Getting started with a new Device Page This is an empty template that suggests the information that should be present on a well-constructed Device Page. This means, that you have to fill it with life and information. There are several “fixme” tags with text on a light background (like this text) throughout this template. As you fill in the page, remove those tags so that people can judge its completeness. When there are no more “fixme” tags left, delete this one too, along with the <WRAP> that encloses it. Keep the articles modular Please include only model specific information, omit bla,bla and put everything generic into separate articles If you have no time to write certain stuff, link to docs base-system should lead the way, do not explain this again DO NOT provide a complete howto here! Instead groom the general documentation.

You will need the following components to get started: A computer with ftp command line utility and Ethernet port. 1–2 Ethernet cable/s (recommended) Ethernet switch OpenWrt firmware image, e.g. openwrt-21.02.0-rc1-ath79-generic-avm_fritz1750e-squashfs-sysupgrade.bin Installation Procedure Please read through all steps before beginning the process and make sure you understand the procedure. Connect your computer and the repeater to the Ethernet switch If you have no switch at your disposal you can try a direct connection. It might be tricky though to persuade your computer into assigning the IP address in time to establish the FTP connection within the available time frame. Configure your computer with a static IP address in the 192.168.178.0/24 subnet, e.g. 192.168.178.10 Plug the repeater into the power outlet and continue as soon as you see LEDs glowing on the device. Connect to the repeater using the ftp command with its IP address 192.168.178.1. On Debian (and many other Linux distributions) you can e.g. use ftp -pnvd 192.168.178.1. This will automatically activate debug and passive modes. Execute the following commands within the FTP session: Replace openwrt-21.02.0-rc1-ath79-generic-avm_fritz1750e-squashfs-sysupgrade.bin with the path to your upgrade image. Make sure your OpenWrt image is in your working directory or, e.g., use the absolute path. quote USER adam2 quote PASS adam2 binary debug passive quote MEDIA FLSH put openwrt-21.02.0-rc1-ath79-generic-avm_fritz1750e-squashfs-sysupgrade.bin mtd1 After you read 226 Transfer complete you can disconnect the repeater from the power outlet. Flash Layout Find out flash layout, then add the flash layout table here (copy, paste, modify the example). Please check out the article Flash layout. It contains examples and explanations that describe how to document the flash layout. OEM easy installation The instructions below are for Broadcom devices and only serve as an example. Remove / modify them if they do not apply to this particular device! This section deals with How you install OpenWrt from a device freshly opened The steps required such as reset to factory defaults if the device has already been configured Note: Reset router to factory defaults if it has been previously configured. Browse to http://192.168.1.1/Upgrade.asp Upload .bin file to router Wait for it to reboot Telnet to 192.168.1.1 and set a root password, or browse to http://192.168.1.1 if LuCI is installed. OEM installation using the TFTP method → generic.flashing.tftp Specific values needed for tftp Enter values for “FILL-IN” below Bootloader tftp server IPv4 address FILL-IN Bootloader MAC address (special) FILL-IN Firmware tftp image Latest OpenWrt release (NOTE: Name must contain “tftp”) TFTP transfer window FILL-IN seconds TFTP window start approximately FILL-IN seconds after power on TFTP client required IP address FILL-IN Upgrading OpenWrt → generic.sysupgrade These are generic instructions. Update with your router's specifics. LuCI Web Upgrade Process Browse to http://192.168.1.1/cgi-bin/luci/mini/system/upgrade/ LuCI Upgrade URL Upload image file for sysupgrade to LuCI Wait for reboot Terminal Upgrade Process If you don't have a GUI (LuCI) available, you can alternatively upgrade via the command line. There are two command line methods for upgrading: sysupgrade mtd Note: It is important that you put the firmware image into the ramdisk (/tmp) before you start flashing. sysupgrade Login as root via SSH on 192.168.1.1, then enter the following commands: cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc sysupgrade /tmp/xxx.abc mtd If sysupgrade does not support this router, use mtd. Login as root via SSH on 192.168.1.1, then enter the following commands: cd /tmp wget http://downloads.openwrt.org/snapshots/trunk/XXX/xxx.abc mtd write /tmp/xxx.abc linux && reboot OEM Restore This section explains how to restore original OEM firmware if the device is flashed with OpenWrt or the firmware is bricked. Preconditions You will need the following items: A computer with Wine (wine32) installed (tested w/ version 4.0) and an Ethernet port. Ethernet cable AVM recovery utility (Download), e.g. FRITZ.Repeater_1750E-07.21-recover.exe Restoration Procedure The following steps are necessary to restore your repeater: Prepare your NetworkManager with a static Ethernet connection Use a static IP address in the 192.168.178.0/24 subnet, e.g. 192.168.178.10 Keep the repeater off the power socket and connect the Ethernet cable with your computer Run the recovery utility, e.g. by executing wine FRITZ.Repeater_1750E-07.21-recover.exe Click “weiter” until a window pops up Select your Ethernet adapter in the pop-up window (“übernehmen”) and continue with “ok” The utility will now wait for the repeater to become available Connect the repeater to the power outlet and as soon as possible select the prepared static IP profile with NetworkManager The utility should log the process of deleting this and flashing that After some minutes the repeater is restored and you can close the utility (If the connection fails you can use an Ethernet switch as described in the OpenWrt install procedure above to get a steady connection) The repeater can be unplugged from the power outlet and will boot OEM Fritz!OS next time it is connected Debricking → generic.debrick Use the OpenWrt FTP install process or OEM Restore described above to restore the repeater if the firmware is bricked. Failsafe mode → failsafe_and_factory_reset Basic configuration → Basic configuration After flashing, proceed with this.
