Hi there Alejandro,
This post is pretty old now, but I will say my 867VAE(-K9) does connect to BT ADSL2+ just fine.
And for ADSL2+, BT use PPoA (ppp over atm) - not PPoE. PPoE (ppp over ethernet) IS however used if
you are going to connect (without their little white BT-branded Huawei FTTC (VDSL) modem) to the later
VDSL service, and plug it straight into the back of your VDSL/ADSL port on the 887VA.
I cannot comment on VDSL setup, or wireless lan, but there are many out there if you search for them.
Here's the basics for a ADSL2+ connection. You're best issuing a "write erase" at the enable prompt to
start fresh, then "reload" and enter basic config to plop an ip address of your internal network on one
of the device's VLAN's.. this way device-specific unknowns can be bypassed initially. (perhaps the
887 has real interfaces as opposed to the 867VAE's switch ports?) If you have a working config by now,
DON'T issue a write erase... It clears the config, and after reload, asks if you wish to enter initial config.
This assumes you are using the internal private network 192.168.1.0 255.255.255.0 on your local lan.
Adjust the config bits below if this is not the same, to match desired address.
The interface needs to be in the right mode firstly:
!
controller VDSL 0
operating mode adsl2+
modem ukfeature (this may not take.. doesn't seem to matter on mine)
!
(Then the basics... )
!
interface ATM0
no ip address
no atm ilmi-keepalive
!
interface ATM0.1 point-to-point
pvc 0/38
encapsulation aal5mux ppp dialer
dialer pool-member 1
!
!
!
interface Dialer0
ip address negotiated
no ip redirects
no ip unreachables
ip nat outside
ip virtual-reassembly in
encapsulation ppp
dialer pool 1
dialer-group 1
ppp chap hostname [YOUR USERID]@[something] <-- as you obtain from BT
ppp chap password [YOUR BROADBAND PASSWORD] <-- as you obtain from BT
no cdp enable
!
!
ip nat inside source list 100 interface Dialer0 overload
!
ip route 0.0.0.0 0.0.0.0 Dialer0
!
access-list 100 permit ip 192.168.1.0 0.0.0.255 any
!
dialer-list 1 protocol ip permit
-Then, ensure you add: "ip nat inside" to the LAN interface you use.. eg if it's a FastEthernet port:
interface fastethernet 0
ip address 192.168.1.1 255.255.255.0
ip nat inside
-If you get an error that you can't apply an ip address to a Layer 2 interface, try:
interface vlan 1
ip address 192.168.1.1 255.255.255.0
ip nat inside
-Then if no errors spew forth, you might do a:
interface dialer 0
shut
no shut
-to get the dialer to initiate a ppp session and acquire an ip address.
-If you do a:
show controller vdsl 0
-you should hopefully see something like:
Controller VDSL 0 is UP
Daemon Status: NA
XTU-R (DS) XTU-C (US)
Chip Vendor ID: 'BDCM' 'IFTN'

.....stuff
Modem Status: TC Sync (Showtime!)

and in there:

...etc. meaning you're synched up to the MSAN/DSLAM whatever.
-I hope some of this is of help. these are taken directly from my 867VAE on BT Business broadband,
as of this moment.
good luck, Jason
