So after loads of power cuts, me messing around with my routers,cables etc i messed up internet up pretty badly. I was interleaved but luckily im back on fastpath, and im now using a zyxel vmg8924-b10a. Iv included some images of my current speed and the adsl checker, 2 bt engineers said my lines are fine but im suffering from crosstalk, will i ever get better upload speed? do my stats look ok? the best iv got recently before all the power cuts etc was 50/6.

I think unless you can figure out why the U2 band is missing you will not get much improvment in upstream sync. Since your Downstream tones either side of U2 band look ok then it's probably something to do with the low power on the upstream.

My attenuation is 12.7dB, so closer the the cab than you (or better quality line in any case), yet my power is a lot higher (12.6dbm down 4.2dbm up)

[Ronski]

I've switched back to my HG612 from the Zyxel, I've lost 7.2Mbps on the downstream (attainable was slightly lower than the sync on the Zyxel), but have gained 2Mbps on the upstream (attainable was pretty much the same as the sync). I shall probably stick to using the HG612 given the boost in upstream, and it makes for a tidier set up.

My upstream had been steadily dropping over the last year or so and got down to 4.5 Mbps.

Yeh iv noticed that before in previous posts, im complete missing bit tones in that area. Bt engineers said my line is fine so i dont really know what to do

Hmm i wonder if i should use the hg612 as my modem and the zyxel as my router then, as the wifis pretty good which has stopped the women of the house moaning lol

[Sheepie]

I think you should listen to ejs from your other post.....

See if you can get openreach to check the upstream power against attenuation on other customers into the same cab see if anyone is breaking the rules on UPBO.

"the use of UPBO has to be mandatory for all players, otherwise it will not be effective"

They would probs look at me like wtf? lol knowing my luck the guy wont even know what UPBO is.

[Sunzz]

Would it be worth trying to contact openreach on the problem? if thats even possible?

[Sunzz]

Heres my stats now, i really need to stop changing routers and stuff lol. Does my connection look good or bad? i think im getting too many errors for DLM to improve my connection right?

ES is the one that matters the most I believe, and 126/204 in a 24 hour period is nothing.

If you really must keep looking I suggest you have a read of this page, it covers both VDSL & ADSL

http://www.kitz.co.uk/adsl/DLM.htm

[NewtronStar]

when I look at those stats the line shows an uptime of 1 hour 8 mins and it is showing 134 ES in that hour so if those errors stayed constant during 23 hours 134ES X 23H = 3082 ES  that is above the DLM speed profile of 2880.

But I don't know if 1 hour 8 mins and 51 secs snapshot was a noisy time of the day 

[ejs]

@NewtronStar

I think you've misread the stats. The 1h 8m 51s has 8 ES, this is 1 hour and 8 minutes into the start of the current 24-hour period. The 134 ES is for the total link uptime, of 1 day 1 hour 8 mins.

[NewtronStar]

Are you sure I ran my own stats for 1H and 3min 26 sec a few days ago have a look.

Edit I see now it says total time = 1 day not 1 hour

yeh i think u may be mistaken Newtron Where does it says 2880 ES on the dlm page? i thought it was <345 errors per day to be classed as Green/Good?

The DLM profiles are usually given in terms of MTBE rather than ES count per day.
MTBE = uptime/ES
ES = uptime/MTBE
(24*60*60)/30 = 2880

So 2880 ES in 24 hours would work out as an MTBE of 30.
