Dsl problems

Legend
last christmas the phone line came away fom the house because the fascia board was rotted
so i called out bt they couldn't attatch the phoneline (because of the rotted board)
so what they did was re-route my phone through my neighbors (apparently each phoneline has 2 pairs of cables in in).
After that I started getting problems, when the phone rang or I used the phone the internet would go down (not every time but most times) and I suspect that it also goes down when the neigbour uses heir phone. Anyway I got the fascia board replaced and finally got off my ass and phoned bt to get the phone line put back up.
the engineer came out and hummed and arred about not being able to get the required height.
He asked me if it was ok to leave it the way it was, I said if you can fix the internet problems yes so he rplaced a joint that had water in it and replaced the wall plate with a i-plate

we tested it and my connection worked fine, however shortly after he left he problem came back

I could get the engineer back out but i know when I try to show him the problem the router will make a liar out of me and it will stay up.
so is there any logging/diagnostic software which will log exactly whats happening so I can show the engineer the problem if using the phone doesn't disconnect the internet while he's here (I know with my luck thats exactly what will happen)
 
if your router supports SNMP, and specifically for your DSL interface you could use cacti to log/graph , SnR , line sync and attenuation. those would show the line shitting itself.
 
Is it bad that I couldn't help reading your post in the voice of George Michael singing 'Last Christmas'? Next time please make it rhyme a bit more though.
 
cacti ?
ps: yes very bad
"last christmas day, the phone line came away"
"away from the house, I said to my spouse"

edit: found cacti
"Cacti requires MySQL, PHP, RRDTool, net-snmp, and a webserver that supports PHP such as Apache or IIS." - I think not ;)
 
whats a routing station
ps: the problem only occurred after i no longer had a phone line and was made to share a neighbors, so im thinking the problem lies there as they have no internet and wont be using microfilters im asuming they are sending noise/voltage down my line although the engineer said the lines are totally seperate. i dont think its a problem at the exchange

ps: saw something weird did a speed test the one with the dial
now it normal quickly goes to the 8mb mark, but on this occasion the needle was jumping rapidly (like twice a second) and continuously between about 200k and 8mb, does that give anyone any ideas.
 
I cant,
Comcast will say sorry we cant lay a cable from our base all the way to the u.k
and my street isnt wired for cable :(
 
There is an amount of bandwidth a line can sustain, depending on distance to the telephone exchange / repeater hub with amplifiers, the type of cabling used and the amount of interference along the way.

That bandwidth is divided into packets, and the amount of packets is divided between upstream and downstream (all unidirectional). Those are essentially multiplexed, so if your bandwidth drops below the minimum amount needed to transmit all those packets, your connection is lost.

There isn't really anything you or the engineer can do about that if the drop of bandwidth isn't at your end.

While DSL as such is point-to-point, it actually only is to the nearest hub / exchange. After that it gets bundled with all the other lines. That "bundle" (mostly glass fiber) has a fixed upper bandwidth limit. If they keep on adding subscribers without increasing that limit, packets get lost. The easiest way to test that is to monitor UDP packet loss.
 
I'm going to guess a few things, first that it's analog DSL (digital signals over copper wires) versus digital DSL (digital signals over fiber optic for example). In the first case there could be all kinds of things affecting your signal stability on your end including the possibility of wonky wiring or insufficient shielding and noise cancellation on your neighbors end. You may also experience degraded performance and speed during windstorms, heavy rainfall and other environmental conditions.

I'd suggest getting your phone company to rewire to your domicile directly again. After all, that's what you're paying them for. Not to have your phone line routed through your neighbors. :p Assuming they do the job right you'll at least have new copper wiring that should be properly insulated and potentially somewhat shielded (old wiring can get a bit wonky in these areas).

BTW - it shouldn't even matter if you are experience problems or not for them to wire directly to your domicile. There's inherently greater potential for privacy invasion by routing through your neighbors place.

These can be a PITA to get sorted out but do persist.

Probably best to get your ISP to run a 24hr monitoring first (assuming this is possible?), that may help show where the fault lies/prove its existence.
Also logging occurence of drops/what happens on your modem lights when it drops may help.

After that they should be able to get the tech back out.

The idea of using the neighbours' 2nd pair seems bizarre unless the houses are linked somehow.
Best stability & performance is likely to come from having your own dedicated wires.

there is an all in one windows installer, run it in a VM guest or something like that, but that assumes your router is capable of SNMP.


edit: i did exactly this when i was having line sync issues.
 
Looks like the UK alright... Narrow, shit-brown two-story brick buildings lining every street. :p

Been having intermittent DSL connectivity issues myself of late. Probably because my ISP bumped me up to a performance profile my copper pair can't quite support. The modem syncs at over 19Mbit/s downstream, and that led to issues in the past so I got knocked down to about 14-15Mbit/s. Now I'm waiting for them to switch me over to VDSL2 which hasn't happened yet (and I don't know when it'll be either), so that's probably why I'm back at the old unsustainable speed grade... *sigh*

Real-world speed isn't much faster anyway (especially upstream, where I actually lost around 300kbit/s), and since big downloads seem to cause my link to drop for upwards of 45 seconds or so I don't consider them doing me any favors with this change. Meh.

Had similar problems with my line. It kept on dropping connection and before doing so internet connection speed would drop off. Changed microfilter and all is well again.
 
I´m not sure if my terminology makes sense in English, I´m trying to free translate from Finnish off the top of my head... but I´ll try my best.

Are you sure your dsl is not installed to the same copper pair than your neighbour, and to higher frequency in the bandwidth spectrum on that same pair? If so, the phone and modem could jam each other by leaking a bit into each others frequency.

Is there static noise in the landline phone that appears when the modem is on and disappears when the modem is turned off? Will the adsl line stay on if the phone is disconnected?

If so, change/install new analog noise filters.

Also, some modems seem to be able to stay online better when set to pure bridged mode instead of NAT. So if you can have a separate modem in bridged mode and a router to allow for lan ip addresses, that may help.
