Modem doesn't connect

[hieutt28]

From 2 days ago the internet modem in my house couldn't connect to internet anymore. Only the power LED is on, other LEDs are totally off, no blink, no flash, nothing. I tried restart the modem, unplug, replug, factory reset, none works. The modem is a rental Vodafone station, TG344... designation. Internet was perfectly fine until 2 days ago. I'm not sure if this is a modem issue or network issue.

Another problem, since I don't speak much German, so calling to service numbers is not exactly a good option for me. Someone help me, please 😞

Hello hieutt28,

in which federal state do you live? Please send also the postal code

Which contract do you have? (e.g. Internet + Phone 100)

Which modem/router do you use? (e.g. Hitron)

Do you use a rental device from us or do you have your own device?

Which error occurs? (Speed too low; Packetloss) Send also screenshots of speedtests (with date and time) and tracerts/ pingplotter measurements in case of packetloss or ping problems.

How is your end device connected to the modem? (LAN; WLAN; additional router; PowerLAN)

Which browser do you normally use? (e.g. Firefox)

Which operating system do you have on your computer? (e.g. Windows)

Beginning and period of the disturbance (e.g. since beginning of April; only in the evening)

Upload a screenshot of the signal values. You can find them in the user interface of your cable router via 192.168.0.1 or via 192.168.178.1 for the Fritzbox.

What measures were taken by the fault hotline (available at 0800-5266625)?
