RCS Partial Service/No Ranging Response received

[ClMcGee]

Hello there. For the last month we are experiencing broadband outages and drops everyday.
Usually while checking Hub logs quickly I can notice a clear connection between Downstream Channels power drops and RCS errors appearing, however signal then gets back to normal until next outage. We've already had 3 engineer visits (last one yesterday, 4-7pm, said it was fine).
And after the last guy left we've experienced outage again around 10pm.
Outages are not so long, but extremely annoying because they are enough to disconnect everything.

Last outages happened just an hour and 30 minutes ago.

And ofc as nothing has been done yet a fresh log of painful packet loss

I hope that the cable will be changed ASAP because this starts to be totally unusable.

[ClMcGee]

So I understand that changing the cable is not a quick process but can you please provide an approximate time required for that or at least tell me if it was booked for my address already or how should I track it/would be notified? (it says "no orders/appointments")

[Steven_L]

Thanks for coming back to us @ClMcGee, I have looked into this on our system and cannot see anything on the notes that shows a cable change appointment has been made. 

I would be happy to to take a further look into this for you but will need a few details to pass account security. Please look out for my message and we can get started. 

Regards,

Steven_L

So after the 5th technician found out that the cabinet connector was as good as dead and changing it connection seems smooth as silk, though for this week we agreed on setting the Hub back to router mode so he can monitor it from time to time and call me back on friday to tell if they can see the problem, because it is too intermittent to be spotted right on sight. Fingers crossed 😄

[ClMcGee]

Update with some data.
New BQM link 

there is almost no packet loss (I would not even count that one red spot, prob smth usual for 10pm)
but latency jitter is somewhat terrifying, though it does not look like local overuse (because i can clearly see that it gets better past 12am), more like still on my side, waiting till friday

Broadband has emerged as an essential part of humans' regular lives . This is due to the fact broadband service permits users to do a lot of factors that they could not do earlier.

Hi CIMcGee, 

Thank you for reaching back out to us here on the Community. 

I am sorry to hear you are still experiencing latency. I have ran a quick live report from our side and can confirm everything does appear to be running within specification with no errors found. 

How have things been since your last post to us?

[ClMcGee]

As I've not experienced any outages for over a week now, I shall say that problem is solved. Everything was tied up to that connector in cabinet box, too sad that it required 5 tech visits, but I am thankful for your assistance. Cheers 😄
