Well when I think I almost understand a bit about ADSL :no: my lines been not to bad recently then around 2.30 yesterday things got weird , FEC didn't look to have changed that much but CRC and ES/hour went way up sync has remained the same so far and SNR remains stable ?
-
It's remained at that sort of error rate since :(
-
I would guess that either a new user has connected close by your circuit or there is an item of equipment that is going faulty -- possibly with a switching mode PSU. :o
-
electric fence may be ?
-
If you have such devices in your vicinity then yes, that might be a suspect.
Take a look at the information on the REIN (http://www.kitz.co.uk/adsl/rein.htm) page and see if it assists in locating a potential faulty piece of equipment within your locality.

According to the ES data, the CRC rate must have reduced after 4pm?
Edit: the ES graph has no data after 15:16
I don't like those logarithmic scales on the CRC and FEC graphs.
-
here's the following ones
-
today's so far
-
and it finally dropped sync 1.30 today which raised snr ( which is almost a flat line ? )but still high errors
-
out with the little radio and a very clear constant click so looks like the near-by fence , the strange thing is last time this happened it was showing up on the snr graph but that is not fluctuating at all ?
-
it's the electric fence :) got it turned of errors fell straight away only problem is farmer needs it on and can't find the reason it's started giving trouble :(
-
Reasons could be --
- Poor earth connection.
- Arcing across poor joints in the energised wire.
- Foliage shorting the energised wire to earth.
And possibly more . . .

He was quite good about it but think he knows less than me about broadband etc , he did say you can turn it off when you want to go on the internet if you want :lol:

well after a lot of field walking ( I've taken it on my self to check all the fences ) I couldn't believe what an length of fencing is connected :o it's 4 good sized fields . I put extra grounding in reconnected fence joints and have got the ES/hour rate down to about 45 on averagebut still have some ideas to try out :fingers:

Nice progress! Keep on trekking. :)
