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=0x028000 card=0x11218086 chip=0x42358086 rev=0x00 
hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'Ultimate N WiFi Link 5300'
    class      = network


iwn0@pci0:3:0:0:        class=0x028000 card=0x12118086 chip=0x42378086 rev=0x00 
hdr=0x00
    vendor     = 'Intel Corporation'
    device     = 'PRO/Wireless 5100 AGN [Shiloh] Network Connection'
    class      = 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
