Be aware; Change from BT ADSL to VDSL on 19.07.1 release

BT changed me over from ADSL to VDSL this week.
I made at the appropriate changes in the network configuration , PPPoE, dsl0.101 etc etc.

I could not get it to work, kept getting NEGOTIATIONS_FAILURE message in the wan setup .
The physical VDSL settings seem ok, seeing a connection being made under the status window, but was not receiving any IP address sett for WAN connection.

After a lot of hair pulling and trail and error, I got it to work by adding a dummy password in the chaps credential settings. Looks like an empty password string does not work for BT in our exchange ( Ford in Scotland)

So if you can't get it to work, try adding a password to the setup under

config interface 'wan'
        option proto 'pppoe'
        option username 'bthomehub@btinternet.com'
        option ipv6 '0'
        option ifname 'dsl0.101'
        option password 'test'

fwiw, known issue with BT. First documented in Jan 2019 in OpenWrt install guide for HH5A - see section 7.5

wiki page updated as it wasn't clear there was a 'space' character for BT password in VDSL config example.
