Replaced everything including the shub.

I still have Post RS errors but in the low thousands. I.E 6648. Is that normal?
Log into you hub and restart it from the GUI this will reset the post rs errors, you shouldn't get hardly any let alone 6000!!!

He placed the hub so it should have been refreshed anyway? That said it's not moved for a while. Let me check.

Re: Occasional Dropouts

You need to reset the post rs errors, post rs are really bad if that high.

---------- Post added at 15:09 ---------- Previous post was at 15:06 ----------

If you're getting post rs errors in the 100s then you still have a big issue, but you're seeing them in 1000s.

The engineer went to go fix the taps or something after the correction here so maybe that accounted for the high rs levels at first?

Pre rs is normal unless really high, you don't want any post rs really.

Your MER is good. See how it goes over a longer time period, but for now it's all looking fine.

Re: Occasional Dropouts

I haven’t worked on a cable modem for quite a while, but they always used to count a few errors in the boot sequence whilst looking to lock to the frequencies so probably that

Re: Occasional Dropouts





So who knows for sure what was wrong since he redid all the wiring but the wiring inside was bad, the cable was worn to boot, it was bent when set up with pressure on it and all the wiring outside was wrong. The engineer was surprised it ever worked and had a very low opinion of whomever set it all up. Also replaced the hub.

Re: Occasional Dropouts

Should i worry about Post ER errors happening occasionally?

After a week of being fine, I just had a temporary dropout.
