cisco877 dsl router basic conf

im having problem  setting up lan ip address on my new 877 router .
when i tried to add an ip to fastethernet 0 or any other i got this
ip address may not be configuered on l2 links. and i could not add the ip to the interface.
any way i searched the internet and i found article said add the fastethernet 0 to vlan 1 and add an ip for the vlan 1 anyway i tried this too and i could not add an ip to the vlan also but with invalid error .
please i need step by step set up because im a newly cisco user.
