Network periodically failing

Question

I'm experiencing some strange network behaviour, after what I assume, was a system update.
I'm using netcfg and have set net-auto and net-profiles in rc.conf:
# Use 'ifconfig -a' or 'ls /sys/class/net/' to see all available interfaces.
# Interfaces to start at boot-up (in this order)
# Declare each interface then list in INTERFACES
# - prefix an entry in INTERFACES with a ! to disable it
# - no hyphens in your interface names - Bash doesn't like it
# DHCP: Set your interface to "dhcp" (eth0="dhcp")
# Wireless: See network profiles below
eth0="eth0 192.168.1.2 netmask 255.255.255.0 broadcast 192.168.0.255"
INTERFACES=(eth0)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
gateway="default gw 192.168.1.1"
ROUTES=(!gateway)
# Enable these network profiles at boot-up. These are only useful
# if you happen to need multiple network configurations (ie, laptop users)
# - set to 'menu' to present a menu during boot-up (dialog package required)
# - prefix an entry with a ! to disable it
# Network profiles are found in /etc/network.d
# This now requires the netcfg package
NETWORKS=(home-wireless)
# DAEMONS
# Daemons to start at boot-up (in this order)
# - prefix a daemon with a ! to disable it
# - prefix a daemon with a @ to start it up in the background

Perodically, wireless doesn't connect (even manually); it gives this log and ends in authentication failed.
Wired is a similar story. It's error message is a simple not connected (or words to that degree).
I've tried restarting all the relevant daemons and checked in /var/log.
However, after an arbitrary amount of reboots, both wired and wireless seem to connect fine

Sorry, your right. That was an old rc.conf.bak. Here is the relevant snippet from the current one:
# Use 'ifconfig -a' or 'ls /sys/class/net/' to see all available interfaces.
# Interfaces to start at boot-up (in this order)
# Declare each interface then list in INTERFACES
# - prefix an entry in INTERFACES with a ! to disable it
# - no hyphens in your interface names - Bash doesn't like it
# DHCP: Set your interface to "dhcp" (eth0="dhcp")
# Wireless: See network profiles below
#eth0="eth0 192.168.1.3 netmask 255.255.255.0 broadcast 192.168.1.255"
#eth0="dhcp"
#INTERFACES=(eth0)
# Routes to start at boot-up (in this order)
# Declare each route then list in ROUTES
# - prefix an entry in ROUTES with a ! to disable it
#gateway="default gw 192.168.1.254"
#ROUTES=(gateway)
# Enable these network profiles at boot-up. These are only useful
# if you happen to need multiple network configurations (ie, laptop users)
# - set to 'menu' to present a menu during boot-up (dialog package required)
# - prefix an entry with a ! to disable it
# Network profiles are found in /etc/network.d
# This now requires the netcfg package
