My wifi does seem to die after a few days.  However the device is
completely different, and the kernel is current:

rpi$ dmesg | grep run0
run0 at uhub2 port 4
run0: Ralink 802.11 n WLAN, rev 2.00/1.01, addr 7
run0: MAC/BBP RT3071 (rev 0x0213), RF RT3022 (MIMO 2T2R), address
e0:cb:4e:bd:b1:31
run0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps
run0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps
24Mbps 36Mbps 48Mbps 54Mbps

so I suspect it is a different issue.  The one time I looked around
(my reflex is reboot :-/), I found restarting wpa_supplicant didn't
help, but restarting dhcpcd did.
