Hi!
I have a problem with hostap when I stream a mpeg video to my notebook per
UDP with VideoLAN (www.videolan.org). In the syslog following message is
coming up from time to time:
#Jan 3 16:26:45 router dhcpd: DHCPREQUEST for 192.168.0.26 from

The data rate is about 4MBit/s and my notebook is about 1m away from the
antenna. The data rate should be constant at 11mbit.
The wireless network is wep encrypted.
When starting the computer, following message is displayed in syslog:

wlan0 and eth0 are bridged together. The kernel used is 2.4.23 on a Debian
Woody system.
Do you have an idea what's wrong?
Thanks a lot!
Sincerly,
Bernhard Roth
PS: I saw in the log a message "driver bug". What do you need to solve it or
to find the reason why this is happening?
