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) https://plus.google.com/u/0/107942175615993706558/posts/Z5CD63e5kmt 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. --=20 Dave T=C3=A4ht Let's go make home routers and wifi faster!
