Hi All,
I am still a little curious to know whether or not my current & ongoing error count points to some sort of connection problem that is potentially still restricting my speeds to an extent.
As I lay in bed this morning at around 07:30 ish, listening to my FM radio alarm, I heard a few seconds burst of what sounded like static interference.
I have never heard this sound of static interference before (at this house), mainly as I usually arise before the alarm starts, & we don't have any other radios in the house.
I have heard it previously at a different house though.
I was at one time somewhere between a CB-er & a rdio ham (I couldn't be bothered to take the exam).
Exactly the same sort of static interference was so bad at that house (prolonged & extremely regular occurences) that I ended up packing in the radio communications hobby.
I only had a 56K modem at the time so it wasn't really affecting my broadband service at all.
So, of course, I dived out of bed (or dove out, for the benefit of any of our trans-Atlantic readers) just to see what effect, if any, it had on my SNRM & error count levels.
Lo & behold, there was quite a spike in error levels.
The last 24 hours of graphs are shown below (hopefully in a format that can be easily viewed).
As I thought my DS SNRM had been running a little lower than the 6 dB target for a while, I decided to re-sync the modem around 30 minutes or so later.
The result was a hike in SNRM to just over 6 dB, & a very slight increase in DS sync speed, along with a very slight increase in download speed.
Apart from this forced re-sync, my modem has not re-synced since 18th November, & SNRM levels have been pretty consistent, but at around 4 dB to 4.5 dB.
I might just try a full modem reboot later on.
So, for anyone who is in the know regarding error levels, do these errors as shown in the graphs point to an ongoing issue to be concerned about?
From other forums, I have seen other users reporting FTTC errors in their tens, or hundreds, over a period of a few days/weeks. Unlike mine where I am now getting much lowe levels than I was, but still experience a couple of thousand or so CRC errors in one hit.
There doesn't appear to be a definite pattern of increase in errors at 07:30 each day.
My central heating switches on at 6:30 every day & the pump runs continuously.
The street lights don't switch on & off at 7:30.
The fridge switches on & off regularly.
Mrs. Eagle hoovers & does other women's household stuff at differing times.
None of the appear to have much (if any) effect upon SNRM or error level spikes.
FYI, I am now collecting my stats every minute rather than every 2 minutes (can't get any more frequent than that for the time being), but I can now see that the errors always occur as a sudden burst within the one minute, rather than prolonged episodes over the space of a few minutes or so.
Paul.
