Hit and miss for me with wpi(4) -- I have two networks, one works the 
other drops out frequently as you describe. A few things different 
between the two networks:

   Working: 802.11a, single AP, WPA-PSK, Airport Extreme 11n, so 
basestation firmware is NetBSD based

   Non-working: 802.11g, WDS, WPA-PSK, Airport Extreme 11g + Airport 
Express 11g (vxWorks?)
