RCS Partial Service/No Ranging Response received

ClMcGee
Tuning in

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.

Your upstream sees the biggest swing. A bad connector or similar somewhere that (partly) interrupts the signal would be my guess (because of the upstream).

So it doesn't appear to be "fine" (intermittent).

slightly lower but still too high, I presume that it could be my cable?

If the next technician that comes around says everything is fine, you could show him the two versions of your numbers. They clearly show that something intermittent is going on which messes with your connection.

well I told the last guy that I can show him the Power logs I saved before, he said that logs "won't tell him what the problem is"
in any case now I have some doubts of my cable because despite visual integrity, it could be damaged, though I won't be able to confirm it before wednesday/thursday 

Hey CIMcGee, thanks for the post.
 

Sorry to see you're having troubles with the connection, I've checked the system and this may need further attention, I will drop you a private message, watch our for the purple envelope. 🙂

 

Thanks.

Thanks, waiting 🙂

While I am still waiting for answer/mail from Virgin staff, I can confirm that nothing has changed with the cable swap, still have the Post-RS frenzy, still have high power spikes on both  Down- and upstream. It could be that I am unlucky though as the moment I am writing this Virgin seems to have big regional/areal issues. Will post again tomorrow.

I could be just Xtremely unlucky, or they are finally solving this while I was trying the cable tricks

Waiting for it :D, hope it will solve that
