An update and preliminary declaration of victory. <br>
<br>
In one of many random config changes (mostly trying to change
channels), I changed the "channel width" from 40 Mhz to 20 Mhz.
Since making that change, the network has been rock solid - no silly
slowdowns. As I understand it, the 40Mhz setting was supposed to
improve bandwidth but I never measured any improvement -- and in
fact, turning it back down to 20 Mhz seems to have solved my
periodic slowdown problem.<br>
<br>
Thanks again for all the help and advice,<br>

I'm looking for some brainstoming ideas to explain why my home
wifi router's performance is suddenly acting so strange:
periodically (about once a day), performance (as tested by
speedtest.net) drastically decreases from ~30Mb/s to ~4Mb/s.<br>
<br>
When this happens, there's nothing I can do to make it better.
Rebooting the router has no effect. The speed comes back when its
good and ready - not before. These "outages" usually last about
12 hours. Performance is bad from all clients - macbook, ubuntu
laptop, phones - so this seems to be router specific - not due to
client config.<br>
