OpenWrt HomeHub 5a BT Infinity PPPoE hangup?

Hello everyone, I am a fairly new BT customer. 

As I need to use my own appliances for study and research reasons, I have been trying to setup my BT HomeHub 5a with OpenWrt SNAPSHOT, r6486-e273860351.

Basically the issue I am facing is, as the modem establish a connection with the cabinet, it suddenly receives a terminate imput and therefore it hangup on the connection. I do believe OpenWrt here has nothing to do with it, but at the same time I want to rule out the modem settings as well.

Configuration:

config dsl 'dsl'
        option annex 'b'
        option xfer_mode 'ptm'
        option line_mode 'vdsl'
        option ds_snr_offset '0'
        option tone 'a'

config interface 'wan'
        option proto 'pppoe'
        option delegate '0'
        option ifname 'dsl0.101'
        option username 'bthomehub@btinternet.com'
        option password 'bt'

config device 'wan_dev'
        option name 'dsl0'
        option macaddr '34:8a:ae:96:e5:eb'

WAN status upon connection attempt(see HANGUP as error code)

root@OpenWrt:~# ifstatus wan
{
        "up": false,
        "pending": true,
        "available": true,
        "autostart": true,
        "dynamic": false,
        "proto": "pppoe",
        "device": "dsl0.101",
        "data": {

        },
        "errors": [
                {
                        "subsystem": "pppoe",
                        "code": "HANGUP"
                }
        ]
}
root@OpenWrt:~#

Here is the interesting part, where we can actually see the whole dialing process taking place:

1) PPPoE authentication has been established:

(Connected to a4:7b:2c:2d:17:63 via interface dsl0.101; peer from calling number A4:7B:2C:2D:17:63 authorized);

2) Local  IP address is 109.156.246.196;

3) Remote IP address(CGN ) is 172.16.18.175;

4) Primary  DNS address is 81.139.56.100;

5) Secondary DNS address is 81.139.57.100;

6) Connection is terminated (LCP terminated by peer; Connect time 0.0 minutes; Modem hangup; Connection terminated).

Lastly I tried quite few DSL modem firmwares for the lantinQ chipset,  see here https://xdarklight.github.io/lantiq-xdsl-firmware-info . Ultimately I ended up sticking with Firmware Version:  5.9.0.12.1.7 as it appears to be one of the latest ones and has Vectoring instructions enabled. Either way, it really made no difference regardless of the versions.

Please help me understanding wheter or not I am doing anything wrong configuration wise. I called BT customer support and when explaining my issue a super rude lady told me BT does not support third party modems and that they are delivering the service promised and that if I am not happy I can go ahead and cancel the contract and that I will be charged for it. 

It really doesn't work like that does it? I am in CSR myself and I would never speak like that to any of my customers.

EDIT: Find attached web configuration screenshot:

Thanks

You are wasting your time with customer support as they are not technical. Obviously BT cannot and  do not support third party devices as there are an infinite number to have knowledge of. However, the operator could have been a bit more civil.

Everything looks to be setting up correctly and authenticating so not sure why the connection is unhappy and forces release.

You will probably get much better information from Open Wrt forums or Kitz forum.

Well spotted, I read what I wanted to see rather than what I saw. Seems odd that it is authenticating ok with wrong username though.

Re: OpenWrt HomeHub 5a BT Infinity PPPoE hangup?

It actually wont authenticate using  bthomehub@btbroadband.com.

Also to clarify the scenario, the HomeHub 5a is a router I purchased off of Ebay and I am not requesting help for it in specific.

I actually just tried using a Draytek Vigor 130 a friend of mine just brought and got the same result. There is no fw alteration here, and if CSR is not technical than please let me speak with somebody who is and understands, regardless of the modem model / version. I cannot run my labs using the HomeHub6, especially because of the CGN.

As already said BT will not help with the changes you want to perform. The hub they provide works perfectly well with bt broadband and the do not support any 3rd party routers or software/firmware

In general. Any technical support is a paid for option and will be limited to vanilla BT devices.

Your first step is to ensure your broadband works ok with a standard BT hub. If it doesn't, then a fault can be investigated, if it does then you are on your own I'm afraid.

What can I say... I am afraid I am better off cancelling it. Sure enough I will leave a "good" feedback on TrustPilot.
