Hi,
I know some of you are very good at this stuff, so thought I would post and see if you could feed back on if im currently getting the max out of my broadband connection?
Im currently on o2 however will be migrated over to Sky. Should I expect similar results and speeds on Sky in peoples experience?
Many thanks for your expert feedback and stats.

Sorry, can't help then .
But if you put your downstream attenuation (33.5) into Kitz it says your Bandwith down is spot on. Your noise margin at 6.0 and 6.5 are very good also so you have a good phone line.
I'm with Sky and have a good connection, I see no reason why yours should not stay the same ...... I switched from TT to Sky almost 2 years ago and they start you on a slow speed, high noise margins and gradually increase your speed over/for up to 10 days but this may not apply to O2 - Sky migrations.
Should I be worried about those HEC errors?
Possibly because the router re-synced at 9:30pm....after sunset is not the best time....try again between 10am and 2pm.
The higher noise margin the better.
The lower line attenuation the better.
Both are dependant on distance and the further away you are from the exchange in the case of ADSL the worse both will be.
There seems to be more to it than this, though. My line attenuation downstream has always been about 42dB which (according to tbe Kitz site) corresponds to a maximum possible speed of about 8Mbps on ADSL2+. However, always with a noise margin of 6 or 7dB I've had actual speeds of anywhere from 0.8 to 7.0Mbps downstream!
Speeds are more stable now after a longstanding line fault was fixed (which was the cause of years of very low speeds and/or intermittent service but they wouldn't fix until a total loss of broadband and phone service occurred!) But just recently the speed increased from 5.3 Mbps to 7.0Mbps again without a change in line attenuation or noise margin.
These are my stats now based on Sky. I can tell from speed test that its slower and looks like the SN is higher on one.

As I said earlier in this thread re-sync during daylight hours, preferably between 10am and 2pm.
But this and all the other errors might indicate a fault somewhere.
It says on the MySky that DLM is not in operation but if I disconnect with this cause DLM to kick in?
DLM should not recognise the power off as a disconnection provided you wait a reasonable time before powering on again.
But that downstream output power figure (if it's not misreported data) may indicate an exchange fault. If it is misreported then the other errors shouldn't be there so something is not right but it may be the result of re-syncing during the night.

Still have this strange figure for the power output so would in your experience think this points to an exchange fault?

If the Error Seconds/Loss of Framing/Los of Signal errors build up then there may be a line fault somewhere.
But if the connection is stable I wouldn't worry about it.
I always thought the opposite, higher noise margin = slower speed.
Correct but I think for the old BT ADSLMax 8Mb it was correct....beerhunter2 might be able to confirm that.....time flies doesn't it ?

Mind you seems to route me to some strange places.
I always use the TBB one rather than speedtest.net which I find quite erratic. I also find the BBC iPlayer Diagnostic test erratic so there seems to be something on my computer which those 2 sites don't like.
Anti-virus software has been known to affect the results from speed test sites.
Also differences can be experienced using wireless and ethernet.
So.....many variables can affect returns from speed tests.
