The problem appears when I start tcpdump on that interface. For few second everything seems normal, but after couple of second the traffic hangs down. The signal strength and quolity matter show that it's working just fine, but neither there is ping response or any traffic passes through the interface. I maintain few linux boxes and noticed that problem with RedHat 8.0. The latest Redhat distro hasing no problems is 7.3 with kernel 2.4.18-3. Any latest version hangs down... here is some informatios as recomended: lsmod: airo 49672 1 ne2k-pci 7232 1 8390 8524 0 [ne2k-pci] 8139too 18120 0 (unused) mii 3976 0 [8139too] keybdev 2976 0 (unused) mousedev 5556 0 (unused) hid 22244 0 (unused) input 5856 0 [keybdev mousedev hid] usb-uhci 26412 0 (unused) usbcore 79040 1 [hid usb-uhci] ext3 70784 2 jbd 51924 2 [ext3] There is no indication fot trouble in /var/log/messages Shell script .. hmm (install Cisco Aironet 350 Series Wireless Adapter) and run: #!/bin/bash modprobe airo ifconfig eth0 192.168.0.1 echo "SSID" > /proc/driver/aironet/eth0/SSID tcpdump -qn -i eth0 Notice that there must be a traffic going throug the access poit (some other clients must be connected too, and generate traffic). I've tested the situation when only I was a client in that AP and no problem occured.
