FC12 losing connection sequentially

hi!

I made a fresh and clean FC12 installation on my notebook. When I connect to the internet via WLAN (WPA Enterprise, 802.1x + Proxy) I lose the internet connection sequentially. This means NetworkManager always tells me that it is connected, but the internet (FF) stops working. When I switch to the console then, wget or yum also don't work.
I've sniffed the traffic at the time the inet didn't work for me and I saw only arp requests (Who is <gateway-ip> and VRRP Announcement-Routing protocol.

So I thought that it is a arp problem. I've set the gateway mac address with arp -s <mac> <ip>. But when I try to have a look at the arp-table by typing "arp", the output doesn't appear (like it hangs). After some seconds or minutes, the internet works again and the arp table is shown.

What the heck is the problem? It's horrible, can't work like that :-(

thank you
