Hi,
I am another of the many people who seem to be having this problem.
I am running Fedora FC3 kernel 2.6.11 with MA111 usb device, but I have been having \
the same problem with previous versions. I leave the MA111 attached all the time. At \
boot - initializing hardware - the light comes on and off again. At - Bringing up \
interface wlan0 - I get SIOCSIFFLAGS: No such device.
Other people comment that there is a problem with hotplug, and that wlan.agent gets \
called from various places. It is possible that part of the problem I am having is \
that I am using shared key WEP security, and that access to a wireless access point \
without security may be easier.
Rather than try to understand what is going on in detail, I have taken advantage of \
the fact that starting the interface works possibly 5% of the time. I have called the \
script shown below from /etc/rc.d/rc.local. It is simply a loop which continually \
tries to restart the interface. I do get an automatically bootable system, although \
it takes time because I have added a 10 second sleep interval between tries. The \
sleep interval may or may not be necessary. Sometimes it starts after a couple of \
cycles and sometimes many more tries. The script only works with WEP security because \
it detects when the interface has been configured for Encryption (An additional line \
containing the word "Security" appears in the output of iwconfig).
I do not use the suggestion of adding "options prism2_usb prism2_doreset=1" in \
/etc/modprobe.conf which just contains "alias wlan0 prism2_usb".
Here is the script:
#!/bin/sh
# the following seems to be necessary to clear the SIOCSIFFLAGS problem mentioned \
above wlanctl-ng wlan0 lnxreq_ifstate ifstate=enable
i=0
while
[ $i -le 20 ]
do
i=`expr $i + 1`
iwconfig 2>/dev/null | egrep Security > /root/myscripts/mytestout
if
[ `cat /root/myscripts/mytestout | wc -l` -ge 1 ]
then
echo "interface is running"
echo $i >> /root/myscripts/wlan0_boot_count
exit 0
else
echo $i "starting wlan0......."
# next is required otherwise wlan start has no effect
rmmod prism2_usb
/etc/rc.d/init.d/wlan start
sleep 10
fi
done
echo "failure after 20 tries">> /root/myscripts/wlan0_boot_count
exit 1
I hope this helps.

Subject: [lwlan-user] MA111 problems at boot
Hi everyone,
I've asked for help with this before, but didn't receive much response. Does \
anyone have any ideas?
I am using a Netgear MA111 USB adapter with Fedora Core 2 running kernel \
2.6.8-1.521. I installed linux-wlan-ng 0.2.1 pre26 and it works just fine, with the \
exception of, what I gather is, a pretty common problem.
If the adapter is plugged in when I boot (or restart) the computer, it is not \
recognized. I found the FAQ that suggests I add "options prism2_usb \
prism2_doreset=1" to modules.conf. Since I have a 2.6x kernel, I popped that into my \
modprobe.conf file, but it doesn't seem to have done anything. I added it at the \
very beginning of the file, before either of these commands:
alias usb-controller uhci-hcd
alias wlan0 prism2_usb
Does that make a difference?
Any help would be greatly appreciated.
Here are the parts of my dmesg output that refer to USB and WLAN. I have attached \
the full dmesg output as a text file, in case I missed anything.
