Hi guys, I have a problem with my Centos 6.4.
I am experiencing a Wireless Disconnects, some time ago I had them constantly each 2-3minutes. After upgrading to new kernel (and other software from "Software Update" I am still exepriencing disconnects but every 10-15 minutes. It makes me angry because I am doing a lot of work with ftp servers.
