I would like some advice on my connection and if you can see if there is any issues.
I was getting 50/10 a while back but now only been getting 20/5 or less recently.
I did contact BT my provider to ask if they could see any issues but they could not after running some tests.
I have installed the HG612 modem with the HH5 to see if the modem of the HH5 had issues.
I have DSLstats running and the Telnet data will be below, so could you have a look and see if anything stands out that could be wrong before I give BT another call.
I need to plug the modem directly into the BT box before I call to make sure the problem is not mine but not done that so far.
If you need more data from stats let me know.
Thanks for any help.

Looks like you're on 'retransmission high'. Is there a possibility of posting the Hlog and QLN graphs? They might help to identify the reason.
-
Indeed, retx high seems odd given the low error counts and 8.7db downstream margin.
More odd is the drop from 50mbps to 16! I know crosstalk can be terrible but a 68% drop?
A line fault or a seriously big new noise source maybe.
As you say, test socket is the first port of call. Has anything else changed in your setup since you were getting 50/10?
-
I get 3 times that sync with a higher attenuation.
You should be getting much nearer your original sync.
Try the modem in the test socket. Run a quiet line test also.
If no improvement definitely call your ISP.
Hlog/QLN would be handy from now and with the test socket in use.

Need to work on my stats reading! :-[
I have a little over double that but with over 9 days uptime on my 4db target line.

Quiet line test was OK I did it a few times recently and just a few minutes ago, no noise at all on speaker of phone.
Engineers have been like a bee's around a bee's nest on my cabinet recently as they have been installing FTP to buildings near me.
Could this be having an impact on me? Others in the area seem to be having the same issues.

Don't think so and router is within 3 feet of the BT socket and socket is the type that isolates the VDSL line.
I will put it on test socket tomorrow through a ADSL filter.

A profile 17a, G.993.2, service uses up to 4096 sub-carriers.
Both the Hlog and QLN plots, that you posted earlier in this thread, are truncated just above sub-carrier 1850 . . . so we have only seen under half of each plot.
-
Edited graphs.
-
much easier if you click on "change tone range" and click "compress" till you fit all 4000 tones in the graph.
This only needs done once and only needs done on 1 graph.
Your posts/attached images can also be edited so you wouldn't need to upload them again.

Looking at the Hlog plot we see that the US0, US1 & a minute touch of US2 bands, along with the DS1, DS2 & DS3 bands, are visible. Some inconsistency in the metallic pathway has resulted in the two shallow depressions visible at approximate sub-carriers 1710 and 3420.
Looking at the QLN plot we see quite prominent "flying gulls" (or "pigeons") in the DS1 & DS2 bands, which hints at some significant cross-talk. From the overall shape, including the DS power cut-back notch in the DS1 band, we can determine that the cabinet is at some distance away from the telephony serving exchange. There is some degree of RF ingress present in the DS1 band.
Overall I believe that the line, between the cabinets and your home (i.e. the D-side), is tending towards the longer end of the range of distances but not excessively so.
-
Yes I am a little away from my cabinet, there used to be a way of recording it but cant remember the site at the moment.
I have always had a good line even on ADSL and got good speeds.
I will see if I can remember or find out how to get my distance from the cabinet, but I would guess less than .25 miles.
Used Google maps:
800 metres
0.497097 Miles

Is there any way I can reset rtx_tx values?
-
note the last reading and subtract?
-
Thanks, I will keep a record here:
This was one taken a few days ago : 92591186
Downstream rtx_tx
92593704 - 01/07/2018
92594240 - 02/07/2018 = 536
92595345 - 03/07/2018 = 1105
92596059 - 04/07/2018 = 714
92596641 - 05/07/2018 = 582
92597200 - 06/07/2018 = 559
92597957 - 07/07/2018 = 757
92598978 - 08/07/2018 = 1021 Phone removed
-
Only a reboot resets some of the retransmission figures.

Openreach visit tomorrow AM.
