Hello Telekom help center,

I am using SPEEDPORT SMART 4 PLUS for my home WI-FI. From the day before yesterday, the internet has not been connected and a yellow blinking light appears in the center of the device. In addition, the display shows the 'Kabel-Fehler(e0)' message.

Could you please let me know how I can fix the error to use my Wi-fi again.
