Post your FTTC line stats & unlocking info

Hi Locky,
with it being a VDSL2 modem the unit only allows DCHP, PPPoE, and VPN protocalls for the WAN port of the router, even though its all in one unit the connection between the Modem and Router is still done via a LAN/WAN ports on Modem and Router chipset

damn, there is no unlock for your BT business modem. phone BT and ask for the EchoLife HG 612, a swap out.

To be honest I can't seeing taking long now for VDSL routers to start popping up at reasonable prices.

Looking at this one as a possible replacement for the BT gear when I send the Draytek back if the Draytek replacement still won't work.

No GIGABIT LAN I know but is has got built in VDSL2 Modem and Wireless N so 2 out of 3 aint too bad if I do need GIG LAN I'll just buy a GIG switch.

looked at the FRITZ!Box Fon WLAN 7390, bit dear though.

I've just gone through with it and unlocked the modem, the main reason I did this was to improve the upload speed by disabling QOS.

So firstly this is what I was getting on October 14th with Sky broadband (LLU) (I didn't test after this date on Sky as the results were depressingly slow!)

Then once BT Infinity was installed on the 27th October the speed increased to:

And since unlocking the modem earlier this morning I'm now getting:

A slight drop in download speed which I expected as the line settled down, but it's a negligible amount and upload and ping have increased significantly in that time.

Thanks to the OP and to all the others that have offered tips and advice in this thread.

You probably have full sync.

The difference is such a small amount I'm inclined to agree, and through testing different locations with speedtest.net I've found that the speeds can vary quite considerably - it's certainly not a case of the closest being the quickest.

I've tried Google but I can’t get any information on this, can LAN1 be used to access the web interface? As I would like to change the IP to 192.168.100.1 and access the web interface through the router. I used to do this with a Linksys AM200 modem when I was with Sky, the router is WAP54GL running Tomato with an IP of 192.168.1.1. This way it's a lot easier to find stats, ect.

if hes unlocked the modem then just load up the stats and check? :confused:

Right, here are the stats:

Locky · 10 Jan 2012 at 18:56

you have full sync, and when the 80mb product comes you will have 90% of that too.

tbh that's not bad for a 1500 meter line.

Anyone have an alternative link for the pdf guide in the OP?

Hi,

I'm having problems accessing the modem through my network.

From the PDF there is the following statement...

There are various cabling options. In the standard setting, the home
router continues to be connected to the LAN1 socket on the Huawei for
'fast bridging'. A second cable from the home router plugs into LAN2 on
the Huawei. This allows internet connectivity at the same time as access to
the Huawei's web interface. Different cable configurations can be selected
through the web interface.

My setup is as follows: -

Modem (192.168.1.1) LAN1 > Draytek 2920n (192.168.1.2) WAN2 - VDSL Connection handled by the router
Draytek 2920n LAN Port 1 > TP Link 16 Port Gig Switch
TP Link 16 Port Gig Switch > Network Devices

No dice on connecting to the modem from anywhere on the network as it is.

If I connect a second cable from LAN2 on the modem to the Draytek LAN Port 2, 3 or 4 it knocks out the internet connection and I still can't access the modem.

Any ideas?

Simpic · 26 Jan 2012 at 11:25

Small bump for any help...

bremen1874 · 29 Jan 2012 at 23:39

Here's mine...

Code:

# xdslcmd info --state
xdslcmd: ADSL driver and PHY status
Status: Showtime
Retrain Reason: 0
Max:    Upstream rate = 25759 Kbps, Downstream rate = 84328 Kbps
Path:   0, Upstream rate = 10000 Kbps, Downstream rate = 39999 Kbps

It’s a lot better than I thought it would be. The original BT speed estimate was 28Mbps, the updated version now says 40Mbps. Judging by the Speedtest.net results I’ve had more-or-less 40Mbps from day one.

David Koh · 1 Feb 2012 at 01:11

Well since im too lazy to hack the VDSL modem how about a Screen shot from a Line tester on Line stats page

As you can see my local DSLAM is on 17a (waiting for Ofcom to ratify it for sale to CPs for sale to us guys in april time)
There is the max and min rate. So here I have potential 120meg, but the planned speeds to be released at 80 meg down.
The BCDM means its a Broadcom card (love google see kitz website) <br>

bremen1874 · 1 Feb 2012 at 01:47

That's a much easier approach. Is the Openreach engineer you kidnapped for the test still locked in your basement?

Edit:

It has just struck me that BT are claiming 40,000kbps as 40 meg when it’s obviously really 39.06Mbps.

Hard drive manufacturers have obviously used the same mathematical trick for years. Does Virgin also fudge the figures in this way?

David Koh · 2 Feb 2012 at 01:31

Where do you get 39998kbps being 39.06mbps? Im confused with the translations your doing between bitrates
