[ENG] Recently very slow internet speed to some targets

[utkuoezdemir]

Hi, I am recently having some speed problems on my cable internet. I'd be glad if you could help me.

Internet speed is critical for my work, since I work as a software engineer.

You can find the information below:

• In welchem Bundesland wohnst Du? Sende bitte auch die Postleitzahl
  

12555, Berlin

• Welchen Vertrag hast Du? (z.B. Internet + Telefon 100)

Red Internet & Phone 400 Cable

• Welches Modem/ Router nutzt Du? (z.B. Hitron)
  

FRITZ!Box 6590 Cable

• Nutzt Du ein Leih-Gerät von uns oder hast Du ein eigenes Gerät?

Eigenes Gerät (my own device)

• Welcher Fehler tritt auf? (Geschwindigkeit zu gering; Packetloss) Schick dazu auch Screenshots von Speedtests (mit Datum und Uhrzeit) und Tracerts/ Pingplotter-Messungen bei Packetloss oder Ping-Problemen
  

Lately I have very slow internet connectivity to some targets. A particular target is a Hetzner server with IP: 176.9.126.1**

Speedtest: https://www.speedtest.net/result/11469575158

PingPlotter:

• Wie ist Dein Endgerät mit dem Modem verbunden? (LAN; WLAN; zusätzlicher Router; PowerLAN)

Both LAN (ethernet) and WLAN devices are affected

• Welchen Browser verwendest Du normalerweise? (z.B. Firefox)
  

All browsers, also the command-line

• Welches Betriebssystem hast Du auf Deinem Rechner? (z.B. Windows)
  

Windows 10, Ubuntu Linux, iOS (all OSes)

• Beginn und Zeitraum der Störung (z.B: seit Anfang April; nur am Abend)

Some time in April. Since then the issue is permanent

• Lade dazu noch einen Screenshot von den Signalwerten hoch. Diese findest Du in der Benutzeroberfläche Deines Kabelrouters über 192.168.0.1 bzw. über 192.168.178.1 bei der Fritzbox.

• Welche Maßnahmen wurden durch die Störungshotline (erreichbar unter 0800-5266625) durchgeführt?

None

Thanks!

Hello utkuoezdemir,

we don't give support for own devices and cannot check the line properly when it is connected. Please connect our loan device and make a pingplotter with it via ethernet. Is only Hetzner affected?

Kind regards,

Claudia

Hi Claudia,

I switched to the router Vodafone lent to me and did the speed tests again. It showed interesting results - some of the speed tests were very slow, like averaging around 2-3Mbps, while other tests to the same server, same IP were getting the full speed - around 430Mbps (I did the speed tests using iperf3 to a server I own hosted by Hetzner).

It was like 6-7 times out of 10 the full speed, 3 or 4 times out of 10 slow speed. My guess is it was related to the different routes my connection followed each time.

Then I switched back to my own router (FB 6590), factory resetted it and went through Vodafone's 3rd party modem activation process again.

After doing that, I started getting the full speeds again - on each and every test this time.

I don't know if the factory reset or reactivation solved the issue, but at the moment the issue is resolved.

I will reopen a ticket if I have the issue repeats in the future. Thanks for your help.

Best,

Utku
