Problems with Wi-Fi connection after update

https://bbs.archlinux.org – Hi,I've got a problem with Wi-Fi connection. When I'm trying to connect by KDE's network manager, it seems it's trying to connect, but finally it says the connection couldn't be established. I think it's because of last update, because I have never changed any settings of Wi-Fi. I have done the update for one year every 3-4 days and I haven't had any problem.I have tried to use other adapters, it's doesn't work too. I've tried to change security settings of my router, but it still doesn't work. The same computer with Windows 7 works fine, (HowTos)
