"ifconfig -v wlan0 list scan" returns:

The AP is sold by Verizon but I suspect it's a rebranded Arris or similar with
a model number of CR1000B (tri-band - 2, 5 and 6G). I should note that other
devices, e.g. Apple, Roku, iwlwifi and iwn, all connect without issue.

There's nothing in what little logging is available on the AP to suggest that
it saw the connection attempt :-( How can I confirm the transmitter is enabled?

Re: kldload hangs loading if_iwlwifi on CURRENT

hey there,
i'm running a CURRENT from Dec 6 and have noticed that when i attempt to load 
the iwlwifi kernel module kldload does not exit. it seems to happen after the 
firmware loads, here's the output from /var/log/messages:



[...]

46.ff18e32a.0 9000-pu-b0-jf-b0-46.ucode op_mode iwlmvm



I can't ctl+c to quit the command, but the system does not hang. i'm able to 
kill kldload in a seperate shell, but future attempts to load the kernel 
module also hang the shell.  also, when kldload hangs i notice that 
if_iwlwifi is *not* showing up when i run kldstat.


here's the PCI device info:
ppt0@pci0:0:20:3:   class=0x028000 rev=0x30 hdr=0x00 vendor=0x8086 
device=0x9df0 subvendor=0x8086 subdevice=0x0030

    vendor = 'Intel Corporation'
    device = 'Cannon Point-LP CNVi [Wireless-AC]'
    class  = network


This is intersting; it's also a CNVi device.



Happy to provide any more debug info if needed.  Thanks!

No.  From all the comments I saw your are not taking the wlan interface
of iwlwifi down *before* suspending as mentioned in the bug in "See
also" on one of yours.

Anything which will come back from resume will not work or crash your
machine.

Try to implement taking the wlan interface down (destory) before suspend
and start it again after resume (create) and see if that helps.

In case poeple wonder -- internally our native drivers do not do much
ddifferent for net80211 but LinuxKPI needs its own driving.  It's on a
list but currently the "hang on boot" is more pressing as other things.

I stand corrected, the router is apparently manufactured by "Arcadyan
Technology Corporation"

thanks so much for the quick response.  i just updated the bug - but 
wanted to confirm here that this allows me to load the kernel module on 
my box now and i'm successfully using wifi.  i'll try to dogfood this 
more tomorrow.


thanks!
