Re: thinkpad wifi/dhclient issue

the last part of this saga is, that i have moved
to a new place, and the issue went away. so it
seems it was router related.  just another strange
story from the home router front.

 for everybody out there who likes a good mystery,
 the 900 ping issue has happened mid-day as well
 for the first time.  it is the equivalent of yanking
 the ethernet cable.  so it is not an exclusively
 resume connected, but resume (and startup) is
 a way to reproduce instantly.

i have realised that i dont have to wait 1 second
between every ping.

sudo ping -f -c 999 8.8.8.8

helps in some cases almost instantly.

this time however when dhclient went to grab
a new lease, it started spinning and had to be killed.
so i made a debug version and hope to gdb attach
to it.

perhaps it is not a timeout, because network activity
must be present, if i dont start pinging, connections
never come back.  so perhaps it is filling up some
buffer?  what a nice guessing game :)

thinkpad wifi/dhclient issue

2014-09-24 Thread frantisek holop 
i have this strange issue with my thinkpad X60s
that i dont remember having before (the machine
was in storage for 2 years)

when i boot up (or resume), i get a dhcp lease
from my home router (another openbsd notebook
also works with that router using a usb dongle run0)

however after i get the lease, connections do not work.
if i rerun dhclient, i get the lease again, and still
no connections.

but the strange thing is, that some ~900 pings
later (~15 minutes), dhclient kicks in life again,
gets another lease, and voila, i have connections.
the 2 dhclient outputs look the same, no difference
whatsoever.  this also does not happen with em0,
connections work right after dhclient.

it definitely looks like some timeout, but timeout of what?
