>Description:
Sysinfo: Dell Inspiron 9300 laptop, NetBSD-i386 3.99.11, Intel® PRO/Wireless 2200 Network Connection 802.11b/g

System boots and connects to local network fine. Network connectivity drops after at approximately 5-15 minutes. Connectivity is regained only after issuing "ifconfig iwi0 down" followed by "ifconfig iwi0 up" and waiting for re-assignment of DNS parameter. This didn't work with kernels prior to 3.99.10 and connectivity was only restored after a reboot.

The logfile below shows the acquisition of the interface after bootup until first loss of connectivity:
