So the 1.5.2 final firmware has been released for the 2750n:
http://www.draytek.com/user/PdInfoDetail.php?Id=129#PdQuLinkInfo

I was on 1.5.2 RC3 and had to switch back to the OR modem since the 2750n was dropping the connection every few days and DLM had reduced sync rate to 55/19 with lots of interleaving. Since switching back to the OR modem I'm back up to 72/20 with interleaving off.

I'd be interested to hear any experiences - changes in sync rate, stability, etc, before I go ahead and prod the DLM monster again.
 
Thank you.

Now that is interesting, off to install it now.

Any issues, new features or surprises with it GeForce?

EDIT: Well, I'm not having a good day, amazing, just had a ****** brief power cut & now have bricked my 2750n.:mad:,not in the mood to sort now.

Our connection is used for business VoIP and interleaving was causing huge problems, so I'm waiting to hear some feedback on 1.5.2 before trying it.

It took about 5 days after switching back to the OR modem for interleaving to be turned off and for the line to get back to its full speed.

Let me know how you get on! :)
 
Been having a few issues with stability, my 2570n originally came with firmware v1.5.1.
Had to send it back to Draytek, as I bricked it due to a power cut while updating firmware.:o
Got it back yesterday with firmware 1.5.2 RC1 installed on it, definitely more stable, & it's syncing higher as well.

Will need to give the line a few days to settle down.
 
Glad you got it fixed!

Mine would not sync at all on 1.5.1, but still wasn't right on 1.5.2 RC1.

One thing I found out from the OR engineer, was they use Huawei & ECI fttc cabinets, & I presume each supply their own VDSL2 kit, & whether this was affecting the 2750n & stability.

Yep, you can tell which your cabinet is depending on the OR modem they provide. If you get a Huawei modem (most are) then you have a Huawei DSLAM.

I seem to remember the 2750n uses a Broadcom chipset which is the same as the one in the HG612 (Huawei OR modem), but I think I remember seeing a couple of 2750n users with other chipsets which definitely caused them problems.

I've not opened mine up yet to find out...
 
Just flashed this, still syncing around 63MBps instead of the 74MBps that the OR modem was holding.

SNR values are clearly wrong as well.

I mean it's stable, but in general I'm pretty unimpressed for such an expensive piece of kit. Will be getting in touch with Draytek shortly...

GeForce: Will be interested to know the out come.

My connection is now more stable, but that may be due to BT capping my line.:(

None too happy about that, presently waiting to see what Ofcom has to say about the matter.

Certainly wouldn't recommend the 2750n to anyone with BT Infinity.

Will let you know when I hear back :)

What has your line been capped to and how do you know?

Just for future reference, you just rename the .all to .rst before flashing to have the unit reset to factory defaults after the flashing's complete :)
 
yea I have my 2750N sitting on my desk unused now, gonna try and sell it somewhere I think. Shame that my ip profile has been now reduced by a lot cos of the constant disconnects. I switch to the or modem and hub and everything is stable.

even if the new firmware for the draytek is stable it will not give me as high a syncs as the bt equipment.

The BT Technical Executive appointed to my case, has told me, he had my line capped to 40/5, due to the constant disconnects.

Mana: Which firmware are you using?

I found 1.5.2 RC1 has been the most stable,& was originally syncing higher than the BT kit, but my line has started playing up in the last few days again, so BT capped it again, & the 2750n isn't syncing at 40/5 which I an now getting with BT kit.

GeForce: Thanks for that tip.

Go to sell the 2750n & should get enough for it to buy a Asus RT-N66U or Billion 7800n in a few weeks.

In all honesty I cant remember, it was the previous one listed on their site. My problem was that when I was using the Draytek, firstly it would sync slightly lower on the download and upload than the original BT equipment. Secondly my infinity connection on it would disconnect and then reconnect roughly every 2 days.

I put up with it for I would say 9 months and it would usually disconnect while I was asleep at 1-2am. However I got fed up when it disconnected in the middle of a gaming session.

Went and replaced it with the original BT equipment and I was expecting the same 2 day frequency disconnections. However they didn't come and the line was a lot more stable with the upload being 1MB higher in sync.

I am pretty certain however that the constant re-connections over the time using the Draytek has locked me in a lower IP profile. I remember when i first got upgraded from 40/10 to 80/20, the Draytek would sync at 57/12. I am now stuck at 45/10 or there abouts.

It isn't a big deal but I would like to get the fastest my line is capable of, just dreading contacting BT India to make it happen.

But yea, do not want to go back to the draytek as I reckon even if the 2 day disconnects are fixed with the latest fw I still will get lower speeds than using BT equipment. Should never have bought it!! :)
 
My problems with disconnections, sometimes 4 or 5 a day, has been ongoing since July this year, after much complaining I did get a D side swap authorised, saw my ping go down to 8-10ms, from the usual 40ms plus, sometimes high as 150ms or more.
But, it didn't last within two days, my connection was back to it's usual mischief.

What infuriates me is I have two poles, one front of house, other bottom of rear garden, both on same cabinet as I'm on.
Currently on front pole, line capped to 40/5, if I could move to rear pole I would see 67/18 according BT checker, which I know is a conservative figure.

aye, using speedtest.net i get a ping of 35ms. My dad recently had fibre installed at 80/20 and he has a 5ms and 74/17 speedtest.

It doesn't help I have an aluminium line but I am estimated on the BT checker as 58/17 so I am pretty sure I am being capped.

Do you have any suggestions about getting an ip profile line reset? I can ring customer support at work but don't want to waste to much time talking to script readers in India. Might try the BT forums as I hear the mods there can book out engineer visits.
 
I wrote to Ian Livingston BT CEO, [email protected] & complained, he appointed a personal BT Technical Executive to my case to resolves my problems.
Have ground to a halt with my case, so I had no choice but go to Ofcom.

After going back to the BT kit my sync speed gradually increased back to its full 74Mbps over about a week period.

Have you spoken to Draytek about this issue?
 
I have spoken to Draytek in the past and they stated that it was most likely the poor quality of my telephone line that was causing the disconnections. What i did notice with the draktek was that when it would sync the upload snr was 6.0 and then gradually over 2 days it would drop to 0 and then eventually I would disconnect and reconnect.

If this would happen with the BT equipment then I would say yes a line fault is present. But with BT equipment my line holds stable for months.

Will be selling the Draytek when I have time.
 
That all sounds very familiar. My downstream SNR has fallen from 7.4dB to about 6.3dB now and is continually dropping, the line will disconnect eventually.

I don't know what's changed between 1.5.2_RC3 and 1.5.2 stable but clearly not enough.

I will keep this thread updated when I get replies from Draytek, but they so far seem unwilling to acknowledge there is actually a problem.
