Every time when Linux box says that quality of connection drops below 10/100 FreeBSD box shows "status: no carrier". Linux connections still function ok. I even bought a large WiFi antenna for FreeBSD box but still have this problem. Is there some "sensitivity" parameter that driver may be setting too low on the card? Why wouldn't the quality of connection with Atheros card be so unstable on FreeBSD? 7.1-STABLE ath_hal: 0.9.20.3 (AR5210, AR5211, AR5212, RF5111, RF5112, RF2413, RF5413) ath0: mem 0xcffe0000-0xcffeffff irq 16 at device 5.0 on pci0 Yuri
