Siemens SL2-141-i

Siemens SL2-141-i ADSL2+ Router with Wi-Fi 802.11g 54Mbps. It is most similar to the RTA1025W from Dynalink After changing the Board ID you can use these firmwares.

Supported Versions

At time of writing, it is not straight-forward to run OpenWRT on this device due to strict checks of the image format and board ID (RTA1025BW_16)

See also https://dev.openwrt.org/ticket/6920

But you can change the Board-ID using cfe-environment and serial console, then you can use the RTA1025W-Builds, e.g. for OpenWRT Backfire.

Save your new configuration to nvram........done

Press any key to reset the board: 

You have to choose 'L' instead of the predefined 'M' to switch to Board-ID RTA1025W_16!

After saving and reboot you can flash any RTA1025W_16-based openwrt-Firmware.
