Latency spikes/disconnects with Connectbox giga

I moved to this flat about 2 months ago and installed gigabit right away. Initially i did not notice these issues. However, as of the last 3 weeks I have constant but random connectivity drops. It is more than a latency spike as i notice the internet not reachable. I also have TP link decos and its easily visible when they go red. Most of the time the connection recovers within a minute, but sometimes a reboot of the router is required. I looked at the downstream/upstream values and suspected my coax cable/wall connection so I made a clean cut on the coax cable and installed a new connector going directly into the router. The values improved but i will attach them as they may be problematic still. 

 

I have to add that other than the disconnects,  when testing my connection i always get 900-950 down/48-49 up with <9ms. So majority of the time, everything works as expected. Im having a hard time figuring out why so im reaching out here. Perhaps it is something to do with my area/usage of surrounding neighbourrs.

Hi, all!

Thanks for the help. Indeed, the problem was with my setup in the cupboard. It was quite old and there were 2 splitters in place. One reduced it by 4 dbmv and the other by another 6! The engineer was surprised i had internet at all.

 

Anyhow, removing the splitters help a lot. I still have lower power on the high frequency as my modem is not in the cupboard - i do not have power outlet in the cupboard as it sits outside the flat so signal is routed into the flat. Not massive issue but something to improve later on.

 

Really appreciate the help!

if the aop is in the meter cupboard, the modem must also be connected to a cable no longer than 1.5 meters

This gray cable does not appear to be the main cable for your property, which should be a green cable. Have you checked the utility closet for the presence of a green coax cable?

In any case, I would advise you to contact Ziggo and have them schedule a technician for you, who will install a proper AOP (Abonnee Overname Punt = main connection socket).

Downstream has definitely improved. I assume upstream power levels are now ~42 dBmV?

Slightly lower power levels on the upper downstream channel IDs/frequencies are perfectly acceptable. These channels are more susceptible to cable attenuation and noise/interference.

Hi @ivandechovsi and welcome on our Community! 

I can see that you followed the advice of the Community Experts and our engineer came by this morning. How is everything going right now? How is your experience? 

Good to read that everything is now working satisfactorily, @ivandechovsi :blush:

If you have any other questions in the future, you will know where to find us. :wink:

The signal appears to be attenuated somewhere within the main coax cable. The downstream signal is quite weak and the upstream signal is too strong.

Could you post one more pictures of the main connection which is now directly connected to the modem?

I made a clean cut on the coax cable and installed a new connector going directly into the router.

You are not supposed to do that.

This is how the modem is connected. I tried with the splitter provided by ziggo, but the downstream signal was much weaker.  I do not know how this is routed to the outside. I have 2 out coax outlets upstairs and readings from them are comparable. 

Yes, upstream is 42-43.5. Good to know, thanks!

Great, thanks for confirming!

The internet connection should be much more stable now.
