[CUWiN-Dev] multiple gateways?

[Bill Comisky]

In lawndale we put up a second gateway (stower) in the old Sears Tower on 
the south side of the building facing south; our existing gateway (wtower) 
there is on the west side facing NW.  These gateways are plugged into the 
same LAN served by the same dhcp server, and as of now have the same SSID 
and channel.

Though they face different directions (sector antennas) and have a fair 
amount of building in between, their radios can hear each other.  There is 
a small amount of overlap on the ground, where one or two nodes can hear 
both gateways.  Will CUWiN "do the right thing" in this scenario, or would 
it be better to make distinct networks with different channels and/or 
SSIDs?

It seemed to work OK for a while, we started with revision 3658.  We were 
having issues with hslsd core dumps and losing the default route.  In 
light of the many recent fixes, I just upgraded the stower node to 
revision 3715 on 8-Dec netbsd snapshot.  hslsd dropped core within a few 
minutes, but has stayed up since I restarted it.  However the default 
route seems wacky.  Instead of having a default route to the gateway given 
by the dhcp server, its default route jumps around, alternately to:

192.168.4.3     # the LAN address of wtower which is still running r3658
169.254.233.14  # standalone node that can see both gateways, which has
 		# a default route to wtower

I think that, when running r3658, the stower node had a route to the 
gateway given by dhcp (192.168.4.1).  I seem to remember seeing some 
changes to dhcpselect recently, though I don't know if this could be the 
culprit.  The stower running 3715 rebooted before I could download the 
core file, but if it happens again I'll try and snag it.
