hi, i'm having troubles with ath(4) in my thinkpad x40 under 5-STABLE. the driver recognizes the ath card, i can configure it with ifconfig(8). ********************************************************* ath0: <Atheros 5212> mem 0xd0200000-0xd020ffff irq 11 at device 2.0 on pci2 ath0: mac 5.9 phy 4.3 5ghz radio 3.6 ath0: Ethernet address: 00:0e:9b:c6:8a:79 ath0: 11a rates: 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps ath0: 11g rates: 1Mbps 2Mbps 5.5Mbps 11Mbps 6Mbps 9Mbps 12Mbps 18Mbps 24Mbps 36Mbps 48Mbps 54Mbps ath0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500 inet6 fe80::20e:9bff:fec6:8a79%ath0 prefixlen 64 scopeid 0x3 inet 192.168.170.38 netmask 0xfffffff0 broadcast 192.168.170.47 ether 00:0e:9b:c6:8a:79 media: IEEE 802.11 Wireless Ethernet autoselect mode 11g (DS/1Mbps) status: no carrier ssid stderror 1:stderror channel 6 authmode OPEN powersavemode OFF powersavesleep 100 rtsthreshold 2312 protmode CTS wepmode MIXED weptxkey 1 wepkey 1:104-bit ********************************************************* problem is, most of the time ifconfig says "no carrier".
