No Internet After Glasfaser Activation: ISP Issue or Dose or Modem Problem?

6 months ago

Hello, yesterday evening I received the Telekom Glasfaser Modem 2, and I completed the setup via the Einrichtungsassistent without any issues. After the process, I received both an email and an SMS, confirming that the configuration of my fiber connection was complete. The SMS specifically mentioned:

"Die Konfiguration Ihres Glasfaseranschlusses ist abgeschlossen. Bitte verbinden Sie nun Ihren Router mit dem Glasfaser-Modem. Details zur Verkabelung können Sie dem zum Glasfaser-Modem beigefügten Anschalthinweis oder den zu Ihrem Router mitgelieferten Unterlagen entnehmen."

You may also see the e-mail that I received attached.

Following this, I connected my TP-Link Archer AX55 AX3000 Gigabit Wi-Fi 6 Router to the modem. However, even though the modem's light is solid green, the router displays an orange light.

Then, I reset the modem and restarted the router, but the issue persisted. Following that, I removed the router and connected the modem directly to my computer via an ethernet cable. But my computer didn't receive a valid IP address from the modem, so I manually set a static IP with the following settings:
IP Address: 192.168.100.2
Subnet Mask: 255.255.255.0
Default Gateway: 192.168.100.1
I was able to access the modem's interface, and I took screenshots of the status page.

On the Status Page, the Link Status under LAN interface shows 0 Mbit/s, which seems to indicate no active connection.
Then I used the "Problem Handling" option to restart the modem from the interface, but this didn't resolve the issue either.

Does the 0 Mbit/s Link Status indicate a problem with the fiber optic socket or the modem itself?

Could this issue be related to  ISP  or is it more likely a hardware issue with the modem or fiber optic connection?

Should I try any further steps, or is it best to contact Telekom support at this point?

I would appreciate any guidance or troubleshooting tips.
Thank you for your support!

      my guess:

      there is a problem with the router or the ethernet cable. please provide additional screenshots from the router GUI .

      Hello, thank you for the answers. My question when I try to do the set up via PPPoE, it asks for credentials, and I didn't receive any credentials from Telekom regarding PPPoE. Are those supposed to be my Telekom account credentials or something else?

      Good morning.

       

      I think the only issue left ist to set up your TP-Link Router correctly for the internet access via an external Fiber Modem.

      Telekom is using PPoE and most important the VLAN ID must be set to the value 7.

      With a router from AVM FritzBox or a SpeedPort it would be way easier because herer you can use automatic setup.

       

      I found this faq on the TP Linke site:

      https://www.tp-link.com/de/support/faq/3659/

      Unfortunatly it's only avaliable in german. Maybe you can send it through a translator.

      Further down on that page is also the example for Telekom.

       

      P.S. A direct connection of your computer for internet to the modem will not work, because of the PPoE session needed for Telekom. The 0 Mbit shown in the interface is just a glitch IMHO. You just have to set up your router correctly.

      hi.

      my answer was overlapping with the others.

      In your screenshot "tplink4.png" you have to change the connection type too PPPoE.

      The rest must be setup according to my link.

      Thanks a lot for the link. It is quite useful, my only question would be how may I get my PPPoE credentials?

      the credentials are normally no longer necessary if the so-called Easy Login is activated. I believe this is on by default.
      You can then simply enter any fantasy values for username and password in the router.
      But you have to select “custom” under ISP -settings and enter the value 7 for VLAN-ID. Otherwise it won't work under any circumstances.
