LLU Speed question

The first 8 months i was with Talk Talk i got 18 meg download speed consistantly on my LLU service. I used speedtest.net all the time to check it. Was pretty happy with this as I'm not that far away from the exchange. Then one day i noticed the speed had gone out the window and was about 2 meg lol. I rang them up and to cut a very very long story short including numerous calls to india, call outs from bt engineers etc etc, the most i can now get is about 14 meg. Have they capped LLU or something? Or am i being fobbed off? I'm practially on top of the exchange so the 'up to 24 meg' seems wide of the mark, i'd have to be sitting IN the exchange for that i assume.

I use a belkin router which has been the one to get 18 meg speeds and also tried the talk talk one (white box) which seemed worse.

Post your router stats so we can tell what you should get.

Type Interleave Path
Status SHOWTIME

Downstream Upstream

Data rate(Kbps)
16187Kb 1004Kb

Noise Margin
12 12

Output power(dBm)
123 199

Attenuation(dB)
21 7

Like i say, i got 18 meg for nearly a year.

And so you should! This is part of the problem:

In reply to a post by garyparson:

Noise Margin

Down NM too high; usually about 6dB. Could be losing you 2 Meg or more.

so how do i change that?

ring india 'yet again' for n'th time and tell them to reset my settings? done that about five times.

Or you could just sign into the members forum , make a request for your line to be put back on a 6db profile and never speak to a Indian call center ever again ( which is how all savvy TalkTalk customer deal with the beast ).

the irony of the fact , that you should never actually use the phone to speak with a company called TalkTalk has not escaped me and neither should it you but heed my words and you will find dealing with TalkTalk becomes allot easier and less stressful .

Use the forum , not the phone . and be clear that you don't ask to be reset , you ask to be put on a 6db profile .

Don't you have some sort of control panel at TT site where you give some short string specifying the Target NM and Interleaving/Fast Path?

Else you need to speak to them.

I'm starting to ponder the point that Talktalk default profile is 12db , we have all seen this enough times to know this to be true .

So my point is , how are they getting away with advertising 16mb when there default uses a 12db SNR when other use 6db as a default and also advertise 16mb .

Would 10% of there customer base be able to get 16mb on a 12db profile ?

ok, gonna try this. have asked for my profile on the forum to be set up.

i'm sure they gave me some drivel about it being unstable if i used that profile but i know for a fact i've had a solid 18 meg for about 8 months prior to it being fubar'd.

will let you guys know what happens. crosses fingers...

they may be right about instability causing the 12db profile to kick in, but as this has developed i'm sure you'd rather find and fix the fault , not adjust something else to hide it or make allowances for it.

If your mechanic restricted your car to 50mph because (there's a lethal wobble at 60mph" you'd probably wonder why he hasnt fixed the lethal wobble.

On a downstream attenuation of 21 db, you should easily be getting 20 meg never mind 18 @ 6db noise margin.I'm also on TalkTalk and my line is longer than yours (29 db atten) yet i'm getting 18.5 meg. Once TT have lowered your profile to 6db noise margin, if your sync speed is < 20 meg, then consider using a Danube Infineon chipset router...most newer Draytek routers will be fine or the Netgear DGN1000 is a cheaper alternative.

Sorry Myth but to carry on your analogy, I've took my car to the mechanic numerous occasions now and they are useless and think i should be delighted at my new lower speed.

I tried to sign up to the forum last night but it wouldnt accept my telephone number and account number that i copied and pasted direct from the talk talk account page, so I've sent them an email to sort it out.

When i finally get on, I'll be able to request the profile to be set (not reset) at 6db.

I am also tempted to buy a newer router, even though I know my router is capable of 18 meg.
ASUS RT-N66U seems to get good reviews

no need to be sorry, we are agreeing with each other. I was just saying there might be an issue that has developed so the instability argument may be valid, but not trying to fix the underlying issue would be pretty poor practice for the ISP.

I was one of the first to sign up with TalkTalk when they started (well, I signed up my parents) and the logins, passwords etc never worked anywhere. Nothing changes eh

They seemed to go through all the motions but nothing happened really. Something must have happened somewhere as I was on 2 meg for a few days. I'll try the 6db thing and report back what happens. I was toying with the newer router mainly for the gigabit ports so I might speed that process up too.

Thanks for the input guys.

TalkTalk Support will never win any prizes for fast fault resolutions and the login problems on there forum are well documented .

If you have sent them an Email about this they hopefully will get to you in a couple of days and then it will be a couple of days for them to respond to your post , three or even four days if you post on a Friday afternoon as the forum is only staffed during weekdays .

Its not perfect but still its better than the phone support .
