Maybe time for a new router/access point? I was having issues with
my original access point (similar: it started to lose power/signal,
if that is the correct way to phrase it) and finally just replaced
it. Of course this happened just following expiration of the
warranty...

Maybe I am doing this wrong, but I keep the passphrase in
/etc/wpa_supplicant/wpa_supplicant.conf:
network={
ssid="ssid name"
#psk="passphrase"
psk="hashed passphrase"
}
Keep wpa_supplicant.conf readable only by root: 0400 or 0600
I run my script to kick off wpa_supplicant at the start of rc.local.
There may be a better way, but it works well enough.

Try running "ntpd -gq" at the end of rc.local to sync the clock.
Then kick off nptd (with your normal settings) following that.
I have been using OpenNTPD (www.openntpd.org) for several years.
Starting OpenNTPD with the "-s" flag should obviate the need for
"ntpd -gq" or ntpdate earlier in the sequence, but I do both (if for
no other reason than to feel I am covering all bases).
Two notes: 1) I am not trying to start an ntpd war by mentioning
OpenNTPD, and 2) "ntpd -gq" is valid only for the stock ntpd
(/usr/sbin/ntpd), OpenNTPD accepts only two or three startup
options, and "-gq" are not among them.
So my rc.local looks something like this:
# wpa_supplicant
/path/to/script
# sync clock
/usr/sbin/ntpd -gq
# start OpenNTPD
/usr/local/sbin/ntpd -s -f /usr/local/etc/ntpd.conf
One final note: the laptop to which I am referring stays in the
house and uses a local timeserver from which to sync; I have high
confidence that "ntpd -gq" will sync quickly, exit, and allow
rc.local to continue to be processed. I have a MacBook which
travels and I use the same sequence in it (sans the wpa_supplicant
stuff, of course) and it seems to work well. YMMV.
Good luck,
Joe
