No signal on WAN + cannot access LAN

Hello,
thak you for the output. Something is wrong, I’m not sure what, but can you please try to update the bootloader to a newer version? In some cases this helps.

You need to perform the serial boot first - please read Omnia - Turris Documentation and follow the Tools and Booting sections.

When you successfully boot the device with kwboot, break the bootloader by pressing any key.

  • Download this file → https://repo.turris.cz/hbl/omnia/packages/turrispackages/omnia-uboot_2022.04-1_arm_cortex-a9_vfpv3-d16.ipk and unpack it to get the file uboot-devel
  • store the uboot-devel on the USB drive, formatted to ext/btrfs/fat FS
  • plug the USB stick to the Omnia
  • start the USB system by typing usb start
  • load the u-boot binary to memory by load usb 0 ${kernel_addr_r} uboot-devel
  • initialize the SPI flash memory by sf probe
  • update the u-boot by sf update ${kernel_addr_r} 0 ${filesize}
  • jump into new u-boot by typing reset

Now the Omnia should boot with a new bootloader, let it boot to the fully running system.
