wlan0 timed out?
 
hello,
i use a wifi usb key on a mandrake 10.1.
every thing works fine during the first 45 minutes.
after 45 minutes, i have lost network wlan0.
iwconfig returns this:
IEEE 802.11FH ESSID:any
Mode:Managed Frequency:2.462GHz Access Point: 00:00:00:00:00:00
Bit Rate:36Mb/s Tx-Power:17 dBm Sensitivity=0/3
RTS thr:2312 B Fragment thr:2312 B
Encryption key:7654-3234-5678-1E43-E754-5672-14 Security mode:restricted
Power Management:off
Rx invalid nwid:0 Rx invalid crypt:0 Rx invalid frag:0
Tx excessive retries:0 Invalid misc:0 Missed beacon:0

it sounds like if i was disconnected from the access point.
and i don't how to reconnect.
i tried a ifconfig wlan0 down
then ifconfig wlan0 up.
but it did not work.

Hi, Try looking in dmesg for any related output (type dmesg in a terminal). It would also help if you gave us the name of your USB key, best would be if you gave us the chip used (lsusb could help a lot in this case).

here it is:

lusb:Bus 003 Device 002: ID 0457:0163 Silicon Integrated Systems Corp.
i use a trendnet TEW424-ub

OK, from what I've gathered, your card might use a zydas based chip. Try looking for a module with a name like zd1211 (#lsmod | grep zd). I think that if you turn off the device, reload the module and turn it back on, all should work.
Code:
#ifconfig wlan0 down
#rmmod xyz (replace xyz by the name of the module)
#modprobe xyz
#ifconfig wlan0 up
Here you might also want to run a dhcp client (just run dhclient; if I remember right, Mandrake uses it)
Try running a ping request in the background, for me, it helps keeping my connection alive.
Another thought, why use such an old distro?
