voice will be prioritised for obvious reasons. On top of this I expect other priority levels exist as well.

this latest noise (the one that requires me to sync very low and occurs at weekends) is not HR related by the look of it.

yesterday I had a almost mirror image of packetloss on my VM and ukonline graphs. Also I have been having a few suspect VM dropouts on healthy stats, which follow packet loss. Which I had previous packetloss graphs show signs of matching, yesterdays is very conclusive.

It would seem this interference which has been forcing me to have 20+db snr margins on the adsl to keep it useable is also affecting my cable. What kind of devices you reckon are capable of also interfering cable? given cable frequency ranges does this new info narrow it down?

It was a pstn fault ,had no line it was totally dead

Well just to update you, the level of packet loss seems to of certainly overall become a lot less, apart from the random 60-80% surge of it, the serious errors are also virtually non at all or only a small amount, so a near max throughput can be achieved, so getting a accurate speedtest result is still hit or miss, but if i download a test file using the IE addon IE pro which has a download manager that you can have upto 10 connections to the source fie file i get a near full speed download,but as a result of the errors,it won't max out the connection fully, i see this by monitoring the ping response times, during shop opening times it is very low compared to when shop is shut and the owner ain't sat in there writing his book, or uploading porn,lol

what is strange is that once the workers have gone home, i see an increase of errors, including of serious errors and throughput slows to an erratic crawl and sometimes the packet loss will increase to a really high amount and no internet rec or send of data is possible but stays in sync

Just had a thought, could this packet loss &errors that cripple my rx throughput be due to the Internet connection in the shop such as cross talk? i doubt that it will be the case but is it possible & is it likely or not,

cross talk is possible yes. cross talk depending on severity can cause major issues.

The reason thought of that as a possible cause or part of it, is that the shop owner has a web site, and frequently updates it, also he receives a lot of e-mail business related, all i was thinking is that he may have some high speed upload connection and that when sending data is creating this crosstalk, i'm just trying to explore other possibilities,with a bit of luck i should be able to have a look at how the telephone wiring is set up ,there maybe something obvious as a telephone cable being next to a mains power cord

Well today he (shop owner ) stayed back for over 1hr 30mins after closing time
causing crc errors and packet loss so after i became really [censored] about it i decided to go and ask him how much longer he intended staying in the shop for as i wanted to use my bb !!!! the shop was in darkness no lights(groundfloor) and the van was parked in it's usual spot so he definitely in there , any way i came home and all interference stopped prior to me checking routerstats ect ,he knows he is causing me problems,and i bet he also has a good idea what is the actual cause, but doesn't want to change anything to stop it, of course it could be just a co incidence that it suddenly stops as i go near the shop,but i doubt it, Today highest level of pkt loss for nearly 2weeks, plus there is some at a earlier time, 100% the thin part, was i think a easynet dns issue as everything data flow stopped pages would not load could not download anything, but remained connected or appeared to, then there is a wider part, that i think is down to tbb.com as r stats was able to ping the bbc without issue at this time

Just a small update which could mean something or not, but ,the owner is away holidays, so i asked the guy who he left in charge if i could have a quick look around at the telephone wiring extensions, and that i wasn't going to touch etc anything, just basically do a visual survey to see if anything obvious stood out such as a power cable running parallel with a phone extension or similar, but he would not let me, saying that i would have to see the boss, i get the impression that they know what is the cause,and don't for whatever the reason want anything changing or me to find out what it is, i have spoken to a bt engineer recently about it he was bb trained too, he had never heard of it before,but said that they may be up to no good, whatever he meant by that I'm not sure, maybe they have something they shouldn't have plugged into the phone line? the other thing i have noticed is that the downstream snr level no longer seems to be completely recovering to the set 4db always 3 db or less even after shop emi has ceased and is now going as low as 1.75db no disconnects Well i'm sick of this now, yet another hour past shop opening hours today before i'm able to use my bb fully i need to find a way to convince the shop keeper that his lights are the cause of my problem, but how? ideas welcome

Well for whatever the reason is things seem to be getting worse.i am getting upto 60% packet loss at times the downstream snr has dipped to 1.2 at times
currently the connection is generating around 900 erroneous seconds every 15mins
and 45,000 crc errors every 15 mins (all errors are downstream) and even browsing is at a snails pace or fails completely

So as the snr has crept in a downwards direction from the set 4db to at best around 2.5db i'm not wanting to re sync as i will loose quite a bit of sync speed and the problem will still be present

I've only 'dipped in' to your thread but thought I would offer this after reading your last post

If you are getting so many errors you may find that your actual 'throughput' is better with a lower sync when not tweaking your Target SNR ! I wouldn't only focus on your actual sync - if your connection runs cleaner with a lower sync your actual broadband experience may be better...
