>Description:
The ralink driver seems to put the card to sleep at random intervals and fails to wakeup or drops the connection. I can bring the connection back up by cycling ral0 with ifconfig ral0 down/up. Going through /etc/rc.d/netif restart also works.
Here is the relevant output of pciconf -lv
ral0@pci0:1:2:0: class=0x028000 card=0xe9351458 chip=0x04011814 rev=0x00 hdr=0x00
vendor = 'Ralink Technology, Corp.'
device = 'Ralink MIMO RT 2661 Wireless 54 Mbps (RT 2661)'
class = network
Here are some excerpts from dmesg, with the last line repeated multiple times.
ral0: <Ralink Technology RT2661> mem 0xd0200000-0xd0207fff irq 11 at device 2.0 on pci1
ral0: MAC/BBP RT2661D, RF RT2529 (MIMO XR)
ral0: [ITHREAD]
ral0: need multicast update callback
Even though I see that irq11 is being used I don't see that with vmstat -i
irq11: cbb0 fwohci*
I'm not certain how to get more information.
>How-To-Repeat:
rc.conf:
wlans_ral0="wlan0"
ifconfig_wlan0="WPA DHCP"
wpa_supplicant.conf:
ctrl_interface=/var/run/wpa_supplicant
ctrl_interface_group=wheel
# Home network
network={
ssid="myssid"
key_mgmt=NONE
wep_tx_keyidx=0
wep_key0=123456789A
