Hi, hope you can help. I've been running the 2850Vn on BT infinity for about a two months now and have not been able to maintain a reliable connection. I have sporadic loss of connection 2-3 times per day, the only solution is to reboot the router.

I'm running a separate DNS & DHCP server (it's also a mail & file server). I could not get the 2850Vn to work as VDSL (followed the guide to the letter), just through the openreach modem and PPPoE - this was the same on two separate client sites. Just flashing VDSL light and no connection. Anyone had any success with VDSL? If so...how? Anyone else had loss of connection issues and could point me with some solutions?

Thanks in advance!

I had mine working via vdsl, it was a pain to setup but I got it to work.

If you still need help let me know and I will post my settings for ya.

@ e.s yes please!

Ok, I shall start from the phone socket.

RJ11 phone wire connected to the phone socket and then connected to the vdsl/adsl socket on the front of the 2850vn.

Then connect an ethernet cable to GigaLAN1 and connect it to the ethernet port on the back of your pc.

That gets the wire connections out of the way

Anyway, open your browser and type 192.168.1.1 and then admin/admin for user and pass, if you have changed the password then use yours instead.

WAN

Goto General Setup and then Click on WAN2, at the top of the page you will see Enable: Yes/No select NO, then push OK.

Do the same for WAN3

Its basically just to make things a little less complicated, you can re-enable these later if you wish.

Next goto WAN1

Enable: select Yes

Type in a Display name that you want the connection to be named after, I just put in Router.

Physical Mode/DSL Mode, it was set to Auto, but I found that auto would sometimes stick on ADSL, so set DSL Mode to VDSL ONLY.

Jump down to VLAN Tag Insertion VDSL, enable it and set Tag Value for 101

Leave everything else alone

Push OK


Internet Access


WAN1 You should see Display Name, Physical Mode, Access Mode and a Details Page. Display name should have what you entered for the name of the connection in the previous steps. Physical mode should have the VDSL letters in green.

set Access Mode to PPPoE/PPPoA

Then click on Details Page then select the PPPoE/PPPoA Tab at the top of the page.

Click on Enable, if it isnt already.
ISP Access Setup, input your ISP Username and Password. PAP/CHAP should be selected and if you have a fixed ip then select Fixed IP and type in your Fixed IP Address in the box, if you have a dynamic ip then leave those settings as is.

Push OK


Multi-PVCs


General

Channel 1 on mine is pre-set for ADSL, so I have unticked and disabled it since I do not have adsl.

Channel 2 is Enabled, VPI 0, VCI 101, QoS Type UBR, Protocol PPPoA, Encapsulation, VCMUX.


I dont know if Multi PVCs is needed for you to connect, but thats what mine was set at automatically.

Multi VLAN

Channel 1 is enabled with add tag set at 101 and priority set at 0

Thats all I have done to mine on the connection side of things, I have enabled the firewall and wireless and usb stuff etc, but apart from that I havent messed with the actual VDSL status/setup settings at all.

I do notice that this router takes ages to actually connect, i.e your pc will take about 3-5 minutes or so before it actually recognises the connection.

Zen is my ISP

I cant add any more text to my previous post, but if for some reason it doesnt connect and if you run windows 7, open thenetwork and sharing centre then click on Troubleshoot problems as that may fix the connection for you, if all the settings are entered into the router properly.

Awesome - thanks for taking the time to put that all down, really appreciated it! At the moment it seems to have smoothed out having discovered an issue with the DoS settings (needed to set ICMP flood defense to 1000 packets/sec and turned off port scan detection). Fingers crossed it's OK from here on in. It's running over WAN2 in PPPoE at the moment so at some stage I'll switch it over to VDSL directly. Presumably there are speed benefits to a direct VDSL connection?
