Cable modem misbehaving

[robertfoss]

My cable modem is misbehaving in a few different ways:

  - Not letting devices connect, especially after running for a few days

  - Not handing out IP-addresses to devices that connect

  - Not routing packets to all IP-addresses. For example, pinging 8.8.8.8 or 1.1.1.1 fails sometimes

I've tried the following, but without it helping:

  - Restarting the router

  - Resetting the router

  - Trying to connect using 5 different devices

  - Opened a support ticket, with Vodafone, ***

I've been trying to fix this for the past 6 days, with no success, and since my vacation is over now, I really need my internet connection to be functional so that I can work.

Hey,

I don't know anything about the signal quality.

I do know that the modem is behaving really badly, and stops allowing devices connect after a while, and requires a hard restart per day. This hasn't been getting better since I started talkinig to support.

Can you please send a new modem? 2 weeks of only sometimes working internet is enough.

Hello robertfoss,

I can see that the signal quality is poor again, so I would like to hire a technician.

When can you be contacted?

I work from home, so any weekday would work. Ideally not between 14-15:00 since I have meetings then.

Could you make sure that the technician brings a replacement modem?

Hello robertfoss,

i instruct a technician. Let us know, what they do.

Hey,

A technician came by, and replaced the modem. The internet connection seemed to work for about a few hours, and then went down again.

The connection has been going up and down since, and will typically stay up for a few hours and the go down for 24 hours or so.

So I would definitely say that my issue has not been solved.

Are other tenants in my building having the same issue? Or is it just me?

I think there are serious signal issues in my apartment, and possibly this entire building.

Hello robertfoss,

i can see the issue and a technician have to look again. Is it ok for you?

And i think also, that is something wrong in the building.

Sure, send one over.

What happens if the signal quality is ok when the technician is over?

[Jens]

Hello robertfoss,

at the moment we are waiting with the technician, because the connection looks good again since one day.

If it worsens, please contact us here.

Jens
