Frequent packet loss, high pre/post RS error counts etc
https://www.thinkbroadband.com/broadband/monitoring/quality/share/7ea541f8314f0f8347708ae1d3c4c63207e4d95a Prior to 30th August I had reported: Downstream - high power levels. Often a lot of pre ...
To close this post. The engineer visited last week and replaced the isolator. This was in the box that is on the inside of the connection coming from the outside, the output of which is the cable that goes into the router.
Since then there have been no postRS errors on the downstream, no T3 timeouts on the upstream, no packet loss.
My broadband connection was put in during the ntlworld days and I don't believe has had the isolator replaced since. That certainly appears to have resolved any issues I had been experiencing over the last few weeks and months.
So thanks Kath_F for arranging the engineer visit.

Prior to 30th August I had reported: Downstream - high power levels. Often a lot of pre and post RS errors Upstream - gone to often 1 or 2 only. Power level is high
30th August - engineer visited and placed a 6db forward path on to the cable. This restored the number of upstream channels
Between 30th August and 14th August I found that apart from a few latency peaks and small amount of packet loss I wasn't experiencing hte loss of service.
14th September - replacement Hub 3 > Hub 5. Prior to replacement no change in upstream channel signal power from prior validation. After the install of the Hub 5 there was a short period of packet loss after 19:00. High number of errors in downstream post and pre RS; small number of T3 timeouts on the upstream channels Below is what I have been experiencing since: 15th September - packet loss 16th September - high latency in the evening 17th September - whilst no loss of service experienced, did get high latency and packet loss in the evening 18th September - whilst no loss of service experienced, did get some packet loss 19th September - whilst no loss of service experienced, did get high latency and packet loss 20th September - upstream power levels have increased to min 45.5 to max 50.5. Packet loss experienced leading to some buffering and short loss of service 21st September - restarted Hub 5 to reset error counts etc. Can see earlier in the afternoon packet loss and latency spikes 22nd September - packet loss for a period of time overnight. High number of pre/post RS counts and T3 timeouts. No latency or packet loss during the day 23rd September - no packet loss, odd latemcy peaks 24th September - packet loss in the evening 25th September - restarted Hub 5 to reset error counts etc. Hub was off from c. 08:20 to c. 10:00
These are the log messages I have had this morning since the restart and I'll post the downstream/upstream info in an updated post

REGISTRATION COMPLETE - Waiting for Operational status
Prior to 30th August I had reported: Downstream - high power levels. Often a lot of pre and post RS errors Upstream - gone to often 1 or 2 only. Power level is high
30th August - engineer visited and placed a 6db forward path on to the cable. This restored the number of upstream channels
Between 30th August and 14th August I found that apart from a few latency peaks and small amount of packet loss I wasn't experiencing hte loss of service.
14th September - replacement Hub 3 > Hub 5. Prior to replacement no change in upstream channel signal power from prior validation. After the install of the Hub 5 there was a short period of packet loss after 19:00. High number of errors in downstream post and pre RS; small number of T3 timeouts on the upstream channels Below is what I have been experiencing since: 15th September - packet loss 16th September - high latency in the evening 17th September - whilst no loss of service experienced, did get high latency and packet loss in the evening 18th September - whilst no loss of service experienced, did get some packet loss 19th September - whilst no loss of service experienced, did get high latency and packet loss 20th September - upstream power levels have increased to min 45.5 to max 50.5. Packet loss experienced leading to some buffering and short loss of service 21st September - restarted Hub 5 to reset error counts etc. Can see earlier in the afternoon packet loss and latency spikes 22nd September - packet loss for a period of time overnight. High number of pre/post RS counts and T3 timeouts. No latency or packet loss during the day 23rd September - no packet loss, odd latemcy peaks 24th September - packet loss in the evening 25th September - restarted Hub 5 to reset error counts etc. Hub was off from c. 08:20 to c. 10:00
These are the log messages I have had this morning since the restart and I'll post the downstream/upstream info in an updated post

To close this post. The engineer visited last week and replaced the isolator. This was in the box that is on the inside of the connection coming from the outside, the output of which is the cable that goes into the router.
Since then there have been no postRS errors on the downstream, no T3 timeouts on the upstream, no packet loss.
My broadband connection was put in during the ntlworld days and I don't believe has had the isolator replaced since. That certainly appears to have resolved any issues I had been experiencing over the last few weeks and months.
So thanks Kath_F for arranging the engineer visit.
