Comment (by bmoffitt):
Late last week I downloaded the "released" CC source to see if anything
had changed, even though I haven't seen any recent checkins that would
make me suspect anything. I have learned to allow for the possibility that
things may have slipped by me...
And there has been a significant change: the "station" device now works
perfectly. I am able to plug in a laptop to the client and access the
network consistently - eth0 no longer "hangs" but, rather, goes down when
nothing is connected and comes back up as soon as it detects an Ethernet
connection. This is terrific, and I would very much like to thank whomever
made the change.
However, there is also bad news: I am running a cron job that simply pings
the router every 5 minutes, and it failed on both devices last night. It
appears that the Ethernet port on the "access point" device is behaving
badly, disconnecting at seemingly random intervals, then taking 4-5
seconds to come back up.
The following is the dmesg text from the AP device, starting from near the
end of the init sequence:

(apologies for the long "code" block)
This link is carrying almost no traffic, outside of the "check" script
that runs every 5 minutes and some pings when I connect a laptop every few
hours. Note that this is the condition under which the link was failing
previously: after a few hours eth0 on the "station" devicewould "go to
sleep" and then fail to wake up when it was connected.
Note: this test was run with Ubiquiti NanoStation LOCO M5 radios running
r46834, which, although I checked it out of the "Chaos Calmer" branch, is
still identifying itself as "Bleeding Edge."
Thanks,
Bill
