# Wireless Monitoring Mode
# Allows SMesh to assess the quality of links, based on signal strenght and
# plausible loss-rate (looking at rssi and retx flag).  This information is 
# available in monitoring interfaces. In WRT54, the interface name is prism0.  
# If defining a monitoring interface in an atheros based card, configure 
# monitoring to use prism2 headers. 
#MONIF="ath1"


# When auto-discovering other mesh nodes in the wireless network, we want
# to enable links that are likely to have good connectivity.  The signal
# strength is a pretty good indicator of quality in most circumstances.  Our
# values are scaled from actual measurement to a percentage.  We use a threshold
# of 28 when in 802.11g (24Mbps), and 35 when in 802.11b (11Mbps). You may look
# at spines.snapshot in each node to see the signal strength value for every 
# neighbor from each node point of view. You should not set a value below 10, as
# you may enable the network to consider pretty bad links in the mesh.  
# IMPORTANT: You need to install libpcap, and have a softlink from libpcap.so
# For example: "ln -s /usr/lib/libpcap.so.0.9.4 /usr/lib/libpcap.so"
# Leave blank if you do not have libpcap shared library
