Glassfiber network ping and jitter is horrible
vor 2 Monaten
I recently made a move from Vodafone Cable 100 Mbps to Telekom GlassFiber (150 Mbps) + SpeedPort 7 router. I am a software engineer working mostly from home and need to have stable internet for work and for gaming. My Vodafone Cable was very stable and good but because GlassFiber was available at my location so I made the switch thinking it would be better for my work and gaming. But ever since I moved to GlassFiber, I am facing issues. My ping is unstable and my internet is pathetic. I raised the concerns about this but I am getting no resolutions so far.
I might lose my job if this continues. I am feeling so bad because of this internet. And I regret moving to Telekom from Vodafone. Here are some screenshots of the misery I face on daily basis. Please note the jitter and ping spikes.

How did you measure the ping?
It seems like Wifi ?

There are multiple ways to check that. You can try doing a ping test on any chosen server on this website.

Or you can also check it via any wifi analyzer apps on your device.

Hello @shivam and welcome to our Telekom hilft Community.
Is @Marius AD right, that the check was done via Wi-Fi? Can you deposit a callbacknumber in your profile and name a timeframe, when you are available for a call, so we can have a closer look at the connection?
Kind regards Sven

Hallo Shivam,
Auf unserer Leitung sehen wir keine Fehler oder Auffälligkeiten. Wenn Dein Heimnetz in Ordnung ist, kann ich gerne eine Verbindung von den Spezialisten überprüfen lassen. Dafür benötige ich jedoch eine aktuelle Verbindung! Ein Trace wäre hilfreich.
Bitte sende mir die Quell-IP und Ziel-IP mit Datum und Uhrzeit sowie den Fehler.
Vg Peter

Hello @Peter Bö. @Khaled A. @Sven Ö.
The line is always fine I guess. And as @DMSE helped me pint point the problem, its more related to my home network and specifically with the Speedport 7 router.
Here are some more trace from this router to 8.8.8.8 destination.
I have done the trace on Wifi and LAN for you to better understand this issue.
If you realize my pain and misery and if its because of this router, please replace it with Speedport Smart 4.

Hi Shivam,
your new LAN MTR comes a bit as a surprise, the values are not too bad any more. As a reference I just did an MTR via LAN to 8.8.8.8 and the best/average ping is basically the same. Also, the average ping on the first hop from your computer to the speeedport does not look to bad any more (best/average ping 0ms and worst ping 15ms).

Surprisingly there seems to be a pattern that every 7th ping spikes. Any idea why this is happening? Is it the same pattern if you connect via LAN?

Hey @Daniel-Wi ,
I am back in Germany. I was trying to reach out to you but I lost your contact detail due to an issue with my cell phone.
Could you please reach out to me so that we can setup the new fiber optic modem and Speedport 4 router I received.
best Regards,
Shivam

you can change your ONT here
https://glasfaser.telekom.de/ont-tausch
after that you connect the new Speedport 4 with the GF Modem 2 and it will configure itself automatically

Hello @shivam,
thank you for the nice phone call. As agreed, I will get in touch again next week on Friday to check if everything is still okay with the Speedport Smart 4. Best regards ^Daniel Wi.
