I've been having trouble with my wireless connection dropping out after a period of inactivity as little as five minutes from booting (depends). I checked iwconfig, and everything looks good:
lo no wireless extensions.
eth0 no wireless extensions.
Warning: Driver for device wlan0 recommend version 18 of Wireless Extension,
but has been compiled with version 17, therefore some driver features

...except the v18 warning, (which doesn't seem to be troubling anyone else online as far as I can tell from my searching), everything seems in order. I've got a 128-bit WEP key, and that works just fine. The problem seems to be it's not recovering from a dropped connection, which I understand just happens with wifi. Is there something I should include in my /etc/network/interfaces file so it knows to reconnect if the wifi drops signal? I've got it in the hotplug section as "map wlan0"
As it stands I have to keep an "active" connection, or reboot if I need remote access to it. I'm running Ubuntu 5.10.
Any ideas? Thanks very much.
