This one has got me stumped. I stumbled upon this issue while I was trying to connect my wife's EEE PC Seashell series 1015PEM to our WD TV Live box through Samba. I successfully connected a Dell Inspiron B130 and a Toshiba Portege M500 to the WD TV Live through Samba (when I say I connected them, I mean I have setup the /etc/samba/smb.conf files on both machines with a network share that the WD TV Live player can "see" and connect to and play files from). When I realized the WD TV Live player couldn't see the EEE PC samba share, I started investigating it with the other machines, and I've come to realize that the Toshiba and Dell computers can see and connect to each other's shares, however the EEE PC can only see and connect to it's own shares (this is through the network view in the Unity and LXDE DE's). However, if I run the smbclient -L [ip_address_of_EEE_PC_machine] it can sometimes see the shares and sometimes not. What makes this problem even stranger is that I cannot ping the EEE PC machine from either the DELL or Toshiba (I get a "DESTINATION HOST UNREACHABLE" error), UNTIL I first ping either computer from the EEE PC (which does work). Once I ping one of the other computers from the EEE PC, then if I retry pinging the EEE PC from either computer, it works...but only for a limited amount of time (like > 5 minutes).

I've looked at the /etc/dhcp/dhclient.conf file, thinking it may be a problem with dhcp somehow. I've even modified my /etc/network/interfaces file so that the ip address is static and doesn't need dhcp at all, neither of these things helped.

I have copied over the smb.conf file from the DELL (which is working) to the EEE PC, but it didn't fix anything. The network interface for wireless on the EEE PC is eth2 whereas it is wlan0 on the Toshiba and the DELL. I'll put the output of ifconfig and my smb.conf file on the EEE PC below.

I should specify that all 3 machines are running the same version of Ubuntu - Ubuntu 12.04 LTS and Samba is the same version on all 3 as well, 3.6.3

smb.conf file:

#
# 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.

#======================= Global Settings =======================

[global]

name resolve order = bcast

## Browsing/Identification ###

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

# server string is the equivalent of the NT Description field
server string = %h server (Samba, Ubuntu)

# Windows Internet Name Serving Support Section:
# WINS Support - Tells the NMBD component of Samba to enable its WINS Server
# wins support = no

# 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
; wins server = w.x.y.z

# This will prevent nmbd to search for NetBIOS names through DNS.
dns proxy = no

# What naming service and in what order should we use to resolve host names
# to IP addresses

#### 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 eth2

# 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
log file = /var/log/samba/log.%m

# 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'.

# 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.
syslog = 0

# 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

# in the samba-doc package for details.

# 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.
unix password sync = yes

# 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).
passwd program = /usr/bin/passwd %u
passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .

This sounds like more of a potential firewall issue specific to that one machine. Could be local (software/OS based), or network-specific (maybe port re-routing)? Can you provide more input on that part of your network setup? I don't think it's necessary to supply your entire samba config. –  gravity May 16 '13 at 13:47
    
This is most likely a driver issue for the Ethernet card on the EEE PC. The entry from ifconfig that reads RX packets:23033 errors:40 dropped:0 overruns:0 frame:91216 shows there are packet and framesize errors (the packets have uneven bit-counts). Run lspci and find the Ethernet controller and start searching for driver-related problems with that controller. It seems that a lot of these issues are related to support in the kernel. –  douggro May 16 '13 at 16:42
    
My apologies for pasting the smb.conf file, thought it might be useful. I have not done anything additional to the EEE PC that I have not done to the other two computers - and none of them have a running firewall. The router acts as a firewall, which is secured using WPA 2. I have no port forwarding configured on the router or on any of the machines. If it was a port issue, I'd think it would affect the other two machines as well. The one thought I had was that maybe the firmware for the netbook was possibly not working correctly. The wireless card is BRCM 4313 & using the broadcom-sta –  aklimatize May 16 '13 at 16:44
    
Thanks douggro, that's the direction I was tending to lean towards as well. I've already googled for information regarding the wl drivers verses the drivers in the kernel under the broadcom-sta package, and most seem to say to use the broadcom-sta package. I tried compiling the wl driver, but came up with an error something to the effect that it couldn't find system.h (which upon checking I discovered that broadcom had not updated their source code to reflect the new placement of the header file in the newer kernel versions). –  aklimatize May 16 '13 at 16:49
    
I meant BCM4313, not BRCM 4313 –  aklimatize May 16 '13 at 17:00
