Severe lengthy timeouts on 500 Cable

zieppa — Tue, 05 Apr 2022 10:43:47 GMT

Hi there,

This is a follow-up to my previous thread which was unresolved until I canceled the contract but realized it will be canceled in one year!!

https://forum.vodafone.de/t5/St%C3%B6rungsmeldungen-Internet-TV/Severe-lengthy-timeouts-on-400-Cable

Again, my ethernet connection is extremely unstable since a few days ago. Would appreciate your help.

Hey zieppa,

sorry that the connection is still not running as it should. I'll be happy to look at it again.

Please send me a PN with your customer data (name, address, customer number and date of birth).

Please contact me again when you have sent me the data.

Kind regards

Moni

Hi @Moni_GK , nice to meet you again! I just sent you my information. Thanks for looking into this.

It's worth a note that the connection is stable today and the timeouts are gone. This was always a sporadic issue as mentioned in the other thread. Three technicians were sent to the place, they found nothing, the last one mentioned that there's a problem with vodafone station in the area that will be fixed in a week or so.

What can we do to avoid this sporadic timeouts in the future? While I don't care for most of the day, it's embarassing when I'm in work meetings 😞

Hello zieppa,

do you do the tests directly on the router or is there still that behind it (Devolo or similar)?

Greetings Moni

Thanks for looking into this, @Moni_GK. Of course, I make the tests when directly connected to the main router to rule out any other external conditions.

Hey,

which interval was set? Is the error permanent or only in the evening?

Greetings Moni

Re: Severe lengthy timeouts on 500 Cable

zieppa — Fri, 08 Apr 2022 09:20:04 GMT

Morning Moni. Interval is always set at 2.5s. Timeouts are sporadic, bad days, good days, not specific to mornings or evenings.

P.S. The most packet lost ratio, I see is at the `83-169-183-71-isp.superkabel.de` node as far as I can see currently.

Hello,

Please write down the exact times when the error occurs.

Greetings Moni

The initial report contains exact timing. Does that help?

I need the current times.
