Quote from: MaldonadoYoure losing sync to your local exchange. Raise an intermittent sync fault with your ISP who will ask you to do the following checks:

(1) Move the router to the master socket
(2) Unplug everything else on the line - telephones, fax machines, burglar / fire alarms, sky systems, etc.
(3) Swap the microfilter
(4) Swap the router, or try your router on a different broadband enabled phone line
(5) Plug your router into the test socket - unscrew the face plate of the master socket and you might see the test socket located to the right hand side.

1) Already there
2) Did it already
3) Checked it with three different filters
4) Its the router they sold us, dont have another available that works with their system.
5) That can wait until they tell me.

call them, ask them to adjust your line profile.  chances are you on the 15db profile, get them to flip it down to the 9db profile.  

I would take a look, but it appears that they have killed my access to Opal Portal since i was last doing TT stuff.  Also, have you checked Talktalk members website?  they do have the network status on there now.  

Edit :: Also, any ADSL 2+ router will work, doesnt matter about brand.  The HG520 isnt the most reliable router in the world.

WTF? Decrease his line profile? That will make any spiking-noise issues worse and cause more disconnections.

Then call them.

yes, decrease it.  you know Plusnets system, i know TTs.  Ive had more luck with clients on 9 and 12 Db profiles than I have on 15.

TTs?

IMO, you dont know what youre talking about. A decrease in target snr will increase the chances of losing sync due to spiking noise.

[Edit: Dont tell you you work for TalkTalk... No wonder you dont know how target snrs affect stability. ]

No, i dont, but i did do some support for them for a few months.  The SNR on TalkTalk seems to be most stable at 12 or 9.  The minimum is usually 6dB for ADSL2, and its still reasonably stable in mostof the time.  ADSL2 and what you supply are slightly different animals.  Ive seen BeThere users who have adjusted theirs even lower than that, and still got a relaible connection.  If the line signal is too high for the line, then youll get the same problems with Sync as if its too low, especially if your line isnt good quality.  If you have a noisy line all that having a higher input signal will do is cause extra interference.  There are some dudes over in TT Support that really do know their stuff, and you pick up enough to know the systems.  As i said, you know PlusNets BT infrastructure, but I know what works best on TTs network, so shut the hell up and admit someone might know a different system that you have Zero experience of.  

One of the lads i work with has his SNR set to 6, and hes pulling 17Mb form TalkTalks network.

Your technical description is poor at best. Im sticking by my statements because theyre correct. When you work full time doing tech support for a decent ISP then let us know.

I bow before the font of all knowledge, he of greater knowledge than myself of systems he has never used, and probably never will.  My description is simplified, because most people dont want to know, or care.  12 or 9 dB usually works best on TTs network.  Proven multiple times, both by me and a few of the guys I work with.  But of course we are wrong, because your ADSL training means you know EVERYTHING there is about helping clients with ADSL2 services as well.  If you think chucking an amplified signal down a copper pair is the only solution to crap line quality then i feel pity for your customers, youll be passing stuff to openreach without a decent reason.

Amplified? Were talking about signal to noise ratio margin or connection profile, i.e. the headroom that your signal to noise ratio has, over the ratio necessary to run at your sync speed. That condensed: higher snr margin = more stability.

Since when did i say that changing the connection profile is "the only solution to crap line quality"?

And since when would we be passing a connection profile change to openreach?

Connection Profile, and on TalkTalk weve proved multiple times that the 15dB profile doesnt always work.  We normally slipped people onto the 12, then the 9 if that wasnt stable.  The MSANs that TT own are the same ones that Huawei ones that other ADSL2 providers use.  

They are "Paired" to the HG520 routers in some resepcts, and the HG520 isnt exactly the best piece of equipment.  They seem to dislike the 15dB profiles , quite often if you drop something decent like a DG834 seris on there they will coem back and work perfectly.

So the equipment that TalkTalk provide isnt suitable for the default connection profile? Gotcha. Now were singing from the same song sheet :D

Am running a DG834V3 (flashed to latest firmware) here, cant fault it, except for that fact that it doesnt do Annex M :(

not so much not suitable, but its fussy.  If you have a crappy line the only solution they have is to turn the line profile down.  It works 95% of the time.

Only Be offer any form of ADSL2+M at the moment anyway...

Im currently on the search for a router that can support the lot, that I actually like where the UI aint a pile of turd.

DG834GT Version 4.  I belive its Annex M capable.
