I'd like to share the setup for cisco routers. Mine is 887va and it can push 39MB fibre. Should also be OK for 78MB fibre.
First the atm0 need to be shut down:
interface ATM0
no ip address
shutdown
no atm ilmi-keepalive
then configue sub interface of ethernet0:
interface Ethernet0.101
bandwidth 38000
encapsulation dot1Q 101
pppoe enable group global
pppoe-client dial-pool-number 1
and configue dialer:
interface Dialer0
bandwidth 38000
ip ddns update hostname xxxxx
ip ddns update xxxxxx
ip address negotiated
no ip redirects
ip mtu 1492
ip nat outside
ip virtual-reassembly in
encapsulation ppp
ip tcp adjust-mss 1452
dialer pool 1
dialer idle-timeout 0
dialer persistent
dialer-group 1
ppp authentication chap pap callin
ppp chap hostname <vodafone PPPoE username>
ppp chap password 0 <PPPoE password>
ppp ipcp dns request
ppp ipcp wins request
ppp ipcp route default
no cdp enable
and configure NAT on the default vlan1:
interface Vlan1
ip address 192.168.0.254 255.255.255.128
ip nat inside
no ip virtual-reassembly in
You also need to enable cef to increse the performace:
ip cef
that's it. My router gets a very good sync:

For wireless AP, a cheap solution is to buy a EE bright box 2, bridge to the wired network, and you can get very good perfomance. This solution is very good for people who are not satisfied with Vodafone router. Cisco integrated service router also supports VPN, firewall, qos etc. pretty useful.
