>Description:
      I'm using the following wlan PCI card:

wi0: <Intersil Prism2.5> mem 0xcf9ff000-0xcf9fffff irq 5 at device 17.0 on pci0
wi0: 802.11 address: 00:0d:54:aa:62:12
wi0: using RF:PRISM2.5 MAC:ISL3874A(Mini-PCI)
wi0: Intersil Firmware: Primary (1.1.0), Station (1.4.9)
wi0: 11b rates: 1Mbps 2Mbps 5.5Mbps 11Mbps

It works fine but only so for 2-3 hours.  At moderate traffic
(80K/s thru a DSL access point, like downloading & building some ports)
after that time, throughput is highly reduced and connections start 
stalling.
Reconfiguring the interface doesn't help.  New connections start at ca. 50%
the bandwidth it would normally use and deteriorate within a minute
to zero throughput (complete stalling).
A reboot of the machine fixes the problem instantly (for another
2-3 hours).
A comparative installation with a different OS showed no such effects.
Another machine running a different OS beside the machine in question
doesn't show the above effects.

>How-To-Repeat:
      I don't know how to reliably reproduce the problem.
It occurs here every time.
>Fix:
      None known.
