On my home network I noticed that wireless transfer slows down a lot over time. It starts at reasonable internet speed of 300kB/s or something but after 2h of using the network it barely gets more than 20kB/s across. Rebooting helps, as does kicking the kernel module/interface and recreating (though that tends to crash from time to time) It's a 03:00.0 Network controller: Intel Corporation Centrino Advanced-N 6205 [Taylor Peak] (rev 34) Subsystem: Intel Corporation Centrino Advanced-N 6205 AGN Flags: bus master, fast devsel, latency 0, IRQ 17 Memory at f2400000 (64-bit, non-prefetchable) Capabilities: [c8] Power Management version 3 Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+ Capabilities: [e0] Express Endpoint, MSI 00 I'm running a freebsd -CURRENT kernel (revision 242489) (actually the Debian kFreeBSD one but with firmware enabled) iwn6000fw.ko is loaded and iwn built into the kernel Regards Christoph --
