F13 wifi goes a little crazy (Networkmanager)

I've a strange problem with NetworkManager on my fedora 13.
The system is up-to-date and kernel is 2.6.34.7-56.fc13.i686.PAE.
Basically, every minute I lost the connection on the wireless interface (wlan0),
only for a couple of second, but it's really annoying when I'm using
skype, for example.
The connection is very simple: it's not secured! I don't have a static
ip, so I must use dhcp.
I never had any problem with other versions of fedora on this network.
I have only F13 on this laptop (HP HDX18).

options cfg80211 ieee80211_regdom=IT
options iwlagn 11n_disable=1 11n_disable50=1 disable_hw_scan=1
I forced this options, doing some researches on the net, but the
problem is still there.
Now I stopped Networkmanager and I'm using system-config-network and I
don't see the messages again (I have to manually insert the network
SSID, of course!), but I'd like to use Networkmanager again.
How can I do ?
