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 } >Fix: >Release-Note: >Audit-Trail: >Unformatted:
