My hardware is detected during boot thus: wi0: <Intersil Prism2.5> mem 0xffbeb000-0xffbebfff irq 10 at device 16.0 on pci0 wi0: 802.11 address: de:ad:be:ef:fa:fa wi0: using RF:PRISM2.5 MAC:ISL3874A(Mini-PCI) wi0: Intersil Firmware: Primary 1.01.00, Station 1.04.02 The card is set up during boot thus: ifconfig wi0 inet 10.0.1.1/24 ssid my_ssid station my_station channel 7 wepmode on wepkey my_key mediaopt ibss Every now and then, the network will disappear, then return anywhere from 30 seconds to three minutes later. On the console and in the logs are entries much like Andrews: Dec 5 13:15:29 mybox /kernel: wi0: timeout in wi_cmd 0x010b; event status 0x8000 Dec 5 13:15:29 mybox /kernel: wi0: xmit failed Dec 5 13:17:51 mybox /kernel: wi0: watchdog timeout Dec 5 13:17:51 mybox /kernel: wi0: timeout in wi_cmd 0x0002; event status 0x8000 Dec 5 13:17:51 mybox /kernel: wi0: wi_cmd: busy bit won't clear.

Dec 5 13:17:51 mybox /kernel: wi0: failed to allocate 1594 bytes on NIC Dec 5 13:17:51 mybox /kernel: wi0: mgmt. buffer allocation failed Dec 5 13:17:51 mybox /kernel: wi0: timeout in wi_seek to 0/0; last status 4000 Dec 5 13:17:51 mybox /kernel: wi0: timeout in wi_seek to 0/44; last status 4044 Dec 5 13:17:56 mybox /kernel: wi0: watchdog timeout The logs are very similar during each "event" and the host becomes unreachable whether via the wireless network or wired network. I haven't been able to get to the console quickly enough to check if the console is also unresponsive, but I wouldn't be surprised. It seems these "outages" occur more often during heavier traffic. They also have increased in frequency since WEP was enabled on the network. Any ideas, anyone? Aaron out.
