Hi,
I didn't know where to leave this, so I e-mailed it to this e-mail address
as prescribed according to
https://www.kernel.org/doc/Documentation/oops-tracing.txt
I did a iwconfig wlan0 txpower 0.
lspci gives me the following device for wlan0:
03:00.0 Network controller: Broadcom Corporation BCM43224 802.11a/b/g/n (rev
01)
I'm running this on a packard bell dot.nl/200 with most of the original
hardware.
I had a tail -f /var/log/syslog running.
root@dotm:/var/log# iwconfig
wlan0 IEEE 802.11abgn ESSID:off/any
Mode:Managed Frequency:2.412 GHz Access Point: Not-Associated
Tx-Power=19 dBm

Encryption key:off
Power Management:off
lo no wireless extensions.
eth0 no wireless extensions.
