I have the following setup a dsl modem/router. As it's reach is not that great or maybe our house is too big :p i have taken out my old linksys router with dr-wrt on it and installed it as repeater bridge according to this guide:
my dsl model router IP is 10.0.0.1 as DNS i use opendns entries so 208....
My Samba server is on ubuntu 12.04 with Samba version 3.6.3. It is connected via a cable to the linksys repeater bridge and I have given it this networks info:
IP 10.0.0.96
subnet 255.255.255.0
gateway 10.0.0.1
dns 208

hostname: SAT
/etc/hosts entries:

127.0.0.1       localhost SAT
#127.0.1.1      SAT
10.0.0.96       SAT

The samba client that I'm trying to connect is connected to via wifi to the linksys repeater bridge and is using dhcp (which is handed out from the dsl modem/router) and looks like this:
IP 10.0.0.79
subnet 255.255.255.0
gateway 10.0.0.1
dns 208
host: darkstar

The problem is that the mounts/samba shares seem unstable sometimes it works for hours at a time and sometimes i can't mount (using IP or hostname) although I can ping and ssh into machines and sometimes it just seems to stop working. Or it does mount, I can see the content of the shared folder but when i want to go deaper it does not work.
Looking into the log files, first from the samba server (10.0.0.96)

some fighting about who is master but seems to be resolved.

Looking at the log files of the samba client (who is also sharing stuff but that is of no interest atm):

and here the config file for the samba server:
#
# Sample configuration file for the Samba suite for Debian GNU/Linux.
#
#
# This is the main Samba configuration file. You should read the
# smb.conf(5) manual page in order to understand the options listed
# here. Samba has a huge number of configurable options most of which
# are not shown in this example
#
# Some options that are often worth tuning have been included as
# commented-out examples in this file.
#  - When such options are commented with ";", the proposed setting
#    differs from the default Samba behaviour
#  - When commented with "#", the proposed setting is the default
#    behaviour of Samba but the option is considered important
#    enough to be mentioned here
#
# NOTE: Whenever you modify this file you should run the command
# "testparm" to check that you have not made any basic syntactic
# errors.
# A well-established practice is to name the original file
# "smb.conf.master" and create the "real" config file with
# testparm -s smb.conf.master >smb.conf
# This minimizes the size of the really used smb.conf file
# which, according to the Samba Team, impacts performance
# However, use this with caution if your smb.conf file contains nested
# "include" statements. See Debian bug #483187 for a case
# where using a master file is not a good idea.

## Browsing/Identification ###

# Change this to the workgroup/NT-domain name your Samba server will part of

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server

# WINS Server - Tells the NMBD components of Samba to be a WINS Client
# Note: Samba can be either a WINS Server, or a WINS Client, but NOT both

# This will prevent nmbd to search for NetBIOS names through DNS.

# What naming service and in what order should we use to resolve host names
# to IP addresses
;   name resolve order = lmhosts host wins bcast

#### Networking ####

# The specific set of interfaces / networks to bind to
# This can be either the interface name or an IP address/netmask;
# interface names are normally preferred
;   interfaces = 127.0.0.0/8 eth0

# Only bind to the named interfaces and/or networks; you must use the
# 'interfaces' option above to use this.
# It is recommended that you enable this feature if your Samba machine is
# not protected by a firewall or is a firewall itself.  However, this
# option cannot handle dynamic or non-broadcast interfaces correctly.
;   bind interfaces only = yes



#### Debugging/Accounting ####

# This tells Samba to use a separate log file for each machine
# that connects

# Cap the size of the individual log files (in KiB).

# If you want Samba to only log through syslog then set the following
# parameter to 'yes'.
#   syslog only = no

# We want Samba to log a minimum amount of information to syslog. Everything
# should go to /var/log/samba/log.{smbd,nmbd} instead. If you want to log
# through syslog you should set the following parameter to something higher.

# Do something sensible when Samba crashes: mail the admin a backtrace


####### Authentication #######

# "security = user" is always a good idea. This will require a Unix account
# in this server for every user accessing the server. See
# /usr/share/doc/samba-doc/htmldocs/Samba3-HOWTO/ServerType.html
# in the samba-doc package for details.
#   security = user

# You may wish to use password encryption.  See the section on
# 'encrypt passwords' in the smb.conf(5) manpage before enabling.

# If you are using encrypted passwords, Samba will need to know what
# password database type you are using.


# This boolean parameter controls whether Samba attempts to sync the Unix
# password with the SMB password when the encrypted SMB password in the
# passdb is changed.

# For Unix password sync to work on a Debian GNU/Linux system, the following
# parameters must be set (thanks to Ian Kahan <<kahan@informatik.tu-muenchen.de> for
# sending the correct chat script for the passwd program in Debian Sarge).

# This boolean controls whether PAM will be used for password changes
# when requested by an SMB client instead of the program listed in
# 'passwd program'. The default is 'no'.

# This option controls how unsuccessful authentication attempts are mapped
# to anonymous connections
