jxself,
Tried the other router, with nothing connected wireless or wired except the
modem. Used the Atheros card to try and connect. Didn't work. Tried 3
kernels, all the same response when giving up: deauthenticating by local
choice reason 3.
Each of the kernels were slightly different in dmesg listings and the
listings themselves were a little different because of this router which has
dual bands, etc. the results were pretty much the same and definitely no
connection at all.
Plugged in the USB WiFi, that again worked just fine.
I can check the dd-wrt forum, haven't done that yet, but things are looking
dim. I've put enough time into this and on a $10 part, it's time to move on.
There's lots I need to figure out in Trisquel yet as I try to set it up for
daily use.
I read about some ath5k bugs:

Trouble since 2008 and still so in 2012. Different from what I am
experiencing but still bugs.
Quite a few WiFi bugs on "deauthenticating" also (a long link but it should
work copy and paste):

Thanks for your help. Hope to hear more about your core boot one day. Take
care.
