WLan randomly suffering from heavy package lost

Hi everyone.
I'm currently running freebsd-7.0-release GENERIC on a dell Inspiron 6400
(i386).
I have a problem when networking via wifi. I have an intel 3945abg
integrated card and I'm using the wpi drivers.
I can connect to my wlan but after one minute or so of perfect
connection the network starts to be terribly slow. I have tried pinging and I discovered that I have a 60%
package lost when pinging something like google or other sites, that goes
up to 90% or more when I increase the package size.
When pinging my router or other computers inside my network I get even
worse performances. (Something like 97% package lost or 100% if increasing
the package size to something like 1400)
With other OSes in my pc everything is fine, other pcs connect without
problem. If I connect via etherneth to the same hub where the wifi
transmitter is connected everything is fine.
I have tried adding to resolv.conf, automatically generated by dhclient,
the addresses of the DNSs of my ISP and
browsing the internet has become a liiitle better, but still very far from the
normal speed. And connecting to other pcs inside my network is still a
pain..
Any idea?
Thank you,
Luca
