SSH - Permission Denied (Public Key)

Now i know im new, but before i get started just know ive read about 3 or 4 different how to's, a few threads and even called a buddy for help but to no avail. Im trying to ssh to my router running on DD-WRT. Ive got my RSA keys generated, placed the public key into Auth_Keys on the server side. So heres the setup;

sshd_config

#Port 22
#AddressFamily any
#ListenAddress 0.0.0.0
#ListenAddress ::

# The default requires explicit activation of protocol 1
#Protocol 2

# HostKey for protocol version 1
#HostKey /etc/ssh/ssh_host_key
# HostKeys for protocol version 2
#HostKey /etc/ssh/ssh_host_rsa_key
#HostKey /etc/ssh/ssh_host_dsa_key
#HostKey /etc/ssh/ssh_host_ecdsa_key

# Lifetime and size of ephemeral version 1 server key
#KeyRegenerationInterval 1h
#ServerKeyBits 1024

# Logging
# obsoletes QuietMode and FascistLogging
#SyslogFacility AUTH
#LogLevel INFO

# Authentication:

#LoginGraceTime 2m
#PermitRootLogin yes
#StrictModes yes
#MaxAuthTries 6
#MaxSessions 10

#RSAAuthentication yes
#PubkeyAuthentication yes

# The default is to check both .ssh/authorized_keys and .ssh/authorized_keys2
# but this is overridden so installations will only check .ssh/authorized_keys
AuthorizedKeysFile  .ssh/authorized_keys

And my debug ( ssh -vvv user@external.ip)

Iv'e tried channing permissions, and everything else i can think of, maybe i just need another pair of eyes to comb it over. Let me know what you guys think.
im setting this up to eventually run a home server.

You've glossed over a lot here. You haven't even given links for the how-tos you're working off - but if you did, that would still be insufficient.

Please show the commands you used to generate and transfer the keys, step-by-step, methodically.

Re: SSH - Permission Denied (Public Key)

To generate;

ssh-keygen -t rsa

Hit enter 3x, so it saved in ~/home/daniels/.ssh/id_rsa (also created the .pub with out a pass phrase
I have physical access to the router which is a Cisco M10 running DD-WRT, so i manually input the public key into the router.
If you need any information just ask, on the how to's most were very similar in nature in the it showed how to generate and disperse the keys and what setting you need on you config files.
I personally think i screwed up my permissions on my user account.
used;

chmod 700 ~/  & chmod 700 ~/.ssh

ending up locking myself out of .ssh so i went under su and set it to

chmod u=xwr ~/.ssh
