I wouldn't bother. I agree with Stefan Monnier
<monnier@iro.umontreal.ca>'s observation that these occur within four
seconds of booting. It is quite possible that these occur because the
boot process has not completed, e.g. a necessary file system hasn't yet
been mounted. From what you describe elsewhere, you are able to get a
connection afterwards. This sounds to me like a separate, harmless,
problem not worth your time.

This sounds reasonable. Suspend likely shuts off the wifi receiver, and
upon ending the system may take a while to bring it back up.
I wonder why it's going into suspend mode; perhaps it is doing so
unnecessarily.

OpenWRT is supposed to be pretty solid these days (although individual
drivers may be problematic. But the interference from neighbors is
worth investigating. You should be able to get a list of neighboring
APs and their channels, but I don't know how to do that offhand. Or
just try a different channel for a week or so.
I have a WRT router, and find it expedient to reboot it occasionally.
