The laptop I've had for some time has an iwn(4) device that has
generally been working well.
I recently acquired a laptop which I've set up for my spouse to use; its
wireless NIC is also detected as iwn(4). However, even when rather
little is going on (as in, she's not using it, because she's off doing
Something Else), I find that its IP address (and thus, its hostname) has
changed. Here's what "pciconf -lv" has to say about them -- first mine,
then the "new" one:
iwn0@pci0:12:0:0: class=3D0x028000 card=3D0x11218086 chip=3D0x4235808=
6 rev=3D0x00 hdr=3D0x00
vendor =3D 'Intel Corporation'
device =3D 'Ultimate N WiFi Link 5300'
class =3D network
iwn0@pci0:3:0:0: class=3D0x028000 card=3D0x12118086 chip=3D0x4237808=
6 rev=3D0x00 hdr=3D0x00
vendor =3D 'Intel Corporation'
device =3D 'PRO/Wireless 5100 AGN [Shiloh] Network Connection'
class =3D network
And here are some representative log entries for the latter:
May 28 00:00:00 g1-241 kernel: wlan0: link state changed to DOWN
May 28 00:00:03 g1-241 kernel: wlan0: link state changed to UP
May 28 04:31:22 g1-241 kernel: wlan0: link state changed to DOWN
May 28 04:31:23 g1-241 kernel: wlan0: link state changed to UP
Have I done something avoidable to encourage this behavior?
Thanks....
Peace,
david
