Draytek 2750n

RogerG · Jul 19, 2012, 14:14:48

Is anybody out there using one of these successfully ? I had a 2800G and it was great, so wanted to sick with Draytek. I asked them and IDNet, and was told he 2750 was a good replacement for the Openreach 'modem'.

FTTC day. BT arrived and connected their box. I made a PPoE connection to the Openreach modem directly from my lapop. Works just fine.

Configured my nice new 2750 with IDNet's credentials and the help in Mikey's guide on the Draytek.
(PPPoE, WAN VLAN ID 101, fixed IP.)

Nothing. Just get Training/Handshake/Idle, no connection. I have set this thing up 4 times now, knowing how easy it is to mess up a parameter, and there was a factory reset between tries 3 and 4.

Have I got a duff Router ? can anybody think of anything else to try ?

Roger, I can't help with the router, but there are a few Draytek users here who may offer some assistance. Just a though, does it work if you configure it to run as a router off the OR modem?

Quotefixed IP

I'm not sure that's right. Surely you'll get the IP allocated by the PPPoE connection.
I guess you've seen the settings here:- http://www.draytek.co.uk/support/kb/kb_vigor_v2750_setup.html ?

Quotedoes it work if you configure it to run as a router off the OR modem

Don't think it has a WAN ethernet port Glenn. It's VDSL or nothing...

Glenn, you guess right, I followed Mikey's guide (http://www.draytek.co.uk/support/kb/kb_vigor_v2750_setup.html ?) to the letter.

MisterW, you too are correct- VDSL or nothing. It's Sooo frustrating !!!! I will wait a day or so and see if I receive enlightenment then I guess I'm going to have to return the router. Draytek are good, but nobody's perfect.

RogerG · Jul 19, 2012, 15:25:55

Fixed IP..... I wondered about that too. I have a fixed IP, so that is what I put in the 2800 config. Config attempts #1 & #2 were with fixed IP, config attempt #3 was DHCP, config attempt #4 was back to fixed. I'm on the BT device at the moment, I might just do a config #5 with DHCP again - it's broken already so no risk !

Glenn · Jul 19, 2012, 15:48:05

Is there anywhere in the settings to input VCI & VPI values? My Fritzbox needs to be set at;
VPI 0
VCI 32

Steve · Jul 19, 2012, 16:50:44

Does it work in bridge mode like the OR modem - just wondering where the issue lies and I agree the IP is allocated via the PPPOE connection.

RogerG · Jul 19, 2012, 17:42:19

Just went through my config with IDNet Support. He thinks the router is broken. Glad I kept the packaging ! I would still be curious to know if any other IDNetters are using this box, though.

Ardua · Jul 19, 2012, 18:03:04

Have you seen this thread? It suggests that others have had similar issues which have been resolved with the latest firmware.

Failing that you could always buy a Fritz!Box - FTTC set up is a breeze. ( sorry I couldn't resist it)

This document (page20) seems to suggest that VCI/VPI can be changed/checked.

QuoteTraining/Handshake/Idle

If that's doing what I think it is then its getting a VDSL connection(Training) but failing the PPPoE discovery/Authentication(Handshake) and then going Idle.
Is the password normally blank for an IDNet PPPoE connection ?, I wouldn't know since I'm not an IdNet customer. If so I seem to recall a bug in the 2750 not liking an empty password field and you needed to enter at least one character.

With my FB7390, I used my original ADSL Username and Password with VLAN 101 set. I am on IDNet 80/20 FTTC. Thinking back, I had issues with Auto settings and I had to set up PPPoE, VLAN VCi etc manually.

That's what was suggested on a BT Infinity forum http://forums.thinkbroadband.com/fibre/4074344-bt-infinity-draytek-2750n-connection-issues.html

QuoteI installed a 2750n this morning and had the same trouble connecting using the bthomehub@btbroadband.com username with no password. I then tried my pre-infinity broadband username/password and it connected straight away.

Ardua · Jul 19, 2012, 20:04:50

Looking at Zen's Draytek FTTC set up advice, Username and Password are also standard when the Draytek is used just as a FTTC router (ie; connected to the OR modem). Leaving the password blank might just be for Infinity.

RogerG · Jul 19, 2012, 20:29:39

Hi Ardua - I downloaded the latest firmware from Draytek before the FTTC install and refreshed the 2750 as soon as I connected it. The 2750 manual has no reference to VCI.

Had a Draytek 2800VG once, awful router, constant disconnections ADSL and wireless

The Fritz 7390 is a lot less troublesome

Ardua · Jul 19, 2012, 20:46:28

Just a thought, what VCI and VPI settings are you using?

MisterW · Jul 20, 2012, 08:01:28

I didn't think VCI/VPI were used on VDSL.
@RogerG, have you tried just leaving it for a while. This http://community.plus.net/forum/index.php/topic,98454.0.html sounds remarkably similar. The two people on there with the same problem, it seems that it just worked eventually.

I have just checked my Fritz!Box 7390 DSL Account Page. It is showing the following settings:

VLAN 101

VPI 1

VCI 38

PPPoE on a DSL connection

MisterW · Jul 20, 2012, 08:43:38

The 2750 doesn't have anywhere to set VPI/VCI. I suspect that's because its VDSL only, whereas the 7390 can do ADSL & VDSL.
AFAIK VDSL/FTTC doesn't have an ATM layer and as such doesn't have VCI/VPI. It uses VLAN tagging, hence the need to set VLAN ID 101. It would be interesting to see if changing the VCI/VPI settings on your 7390 has any effect...

Have a look at the PDF that I sent you in an earlier e-mail - VDSL Security Settings. Page 20 suggests that you can access the settings which should be detected automatically. As I said earlier, my FB didn't pick up theses settings automatically. I have no idea why but after I did a manual configuration it worked. That said, VDSL does take a while to connect - much longer than ADSL.

Setting VCI and VPI was on advice from others who had used FTTC from the start. There are no threads suggesting that these settings are unimportant when using VDSL. I am reluctant to play around with my settings to prove a point as my modem has remained in synch since BT last did some PEW on my exchange some weeks ago.

I left it on for 2 hours before carefully packing it away and asking broadbandbuyer for a replacement.
