Hi guys, I have a really strange problem with my connection. Basically the wifi seems to work (indeed i'm posting this with the connection i got problems with), it connects and it loads pages, download files, etc... but suddenly it stops working, it still shows it's connected, but the transfer rate drops to 0 KB/s. When this happens I try to disconnect and re-connect and it seems to work again, but just for half a second, then it drops again to 0 KB/s. The only way to have it work again (for about half an hour) is to restart the computer. If this can help I had the really same problem with linux mint on KDE (now I'm on Fedora with GNOME). My wireless driver is ath5k and i set my Ipv6 to "local" because in the network manager's log it looked to be unable to "connect to the Ipv6". Now it is no more unable to connect to Ipv6, but the problem is still the same. If I can tell you more in order to help me, please just ask me. Thanks a lot and sorry for my english!

EDIT: every time I lose connection I get this:

A couple threads I read suggested this was permissions but I didn't see any indication of where these should be changed.

The above errors seem to be related to the fingerprint daemon. Not sure how it's connected to networking. Please look at the dmesg log or /var/log/messages for any errors on disconnection.

the problem is it doesn't disconnect, it's still connected but doesn't load pages, download files, etc..

Have u tried a yum update? if not, please do "yum update" as root and check if the problem is still there!

Many users remove Network Manager because it is ... problematic. On my XFCE spin, I replaced NM with wicd because NM does not provide a decent wireless scanner. In NM you have to manually enter the wireless settings. Wicd, on the other hand, autodetects all of the wireless properties - you just have to enter your password. During my own troubleshooting, I found lots of posts that said, "the first thing I do in a new install is remove NM." So,

sudo yum install wicd
sudo yum remove NetworkManager

In some versions of wicd, its gui wireless scanner does not appear when you right-click on the tray icon. So I just created a shortcut in my panel that runs "wicd-client -n", and I click that icon when I need to manage my networks.

Note: I'm using F16, and the version of wicd that the F16 package manager installs is buggy - it would not work on my system. I had to d/l the dev version from here.
