I've been having this issue with my Thinkpad T61 that is running Fedora 7 x86_64, but I've also had it with my older Thinkpad T30 in the past while running Kubuntu. I'll be using my laptop and wireless is working fine and then for some reason the wireless signal gets lost and I become disconnected from the network. Then the only way I've found to get reconnected to the network is for me to reboot, which is just completely annoying.
So what I'd really like is a command or set of commands that can be run so that I can re-connect to the wireless network without rebooting.
Thanks in advance.
