I'd put "broadcast" in the uci config file, that didn't h= elp.

After googling a bit, someone suggested adding

--retries=3D2 --timeout=3D5 --tryagain=3D310 to the

/lib/netifd/proto/dhcp.sh invocation...

And that worked, after a few minutes. I'm irked enough to poke at it harder, but I'm curious if anyone here had come up with a solution?
(I'd actually always assumed it was a quirk in my particular brand of cablemodem, but I got a new one, and it did the same thing)

That said, I'm irked enough at it, and at how long it takes, to poke into it harder (lots of reboots here of late), the best idea I can
think of is to have udhcpc have an option to save the last xid and ip
info to flash and always start in a renew state, using that. The
modems tend to offer a 192.x for about a minute when they boot, tho,
so I guess we'd defer writing that until it had been stable for an
hour.
