VDSL Internet connection dead on a TD-W8970

Installing and Using OpenWrt
1

Hi, I have the latest version of OpenWRT installed on my TD-W8970 as per the wiki. I can't get it to connect to my VDSL connection here in the UK. I have a PlusNet account and have tried the settings below. PlusNet is owned by BT and uses the BT OpenReach network, so I have assumed it uses the same settings. It definitely uses an ADSL VLAN ID of 101

I'm sure that it is something silly that I've missed, but I just can't spot it. Thankfully, I have a another different working router which I can use to get an internet connection until I fix my TD-W8970.

Does anyone have any suggestions as to what I have misconfigured?

/etc/config/network

config dsl 'dsl'                
        option annex 'b'              
        option ds_snr_offset '0'      
        option tone 'a'  

config interface 'wan'                       
        option device 'dsl0'                 
        option proto 'pppoe'                 
        option keepalive '5 5'               
        option ifname 'dsl0.101'             
        option mtu '1500'                    
        option username 'my_username@plusdsl.net'
        option password 'my_password'            
        option ipv6 '0'                       
        option delegate '0'

The logs give me:

It's strange that you have both device and ifname parameters at the same time. Try setting device to dsl0.101 and removing ifname.

Yes, option ifname is deprecated. Use option device only.

I changed it as advised by @patrakov & it fixed the whole problem. Thank you.

This is my working config for PlusNet in the UK

config dsl 'dsl'

        option ds_snr_offset '0'               
        option tone 'a'

config device                                
        option name 'dsl0'                   
        option macaddr 'e8:94:f6:e5:83:e1'

config interface 'wan'                       
        option device 'dsl0.101'             
        option proto 'pppoe'                 
        option keepalive '5 5'
