It would loose connection in FreeBSD, but worked fine in windows. After much experimenting, I found that it was related to the encryption settings. If I switched from using wpa2 to WEP, everything was stable. Then I got another clue when my Mother had the same problem with her McIntosh computer loosing connection with wpa2 and her router. When she got another router, her problems went away. It turned out that the issue was a problem between the implementation of wpa2 in the Netgear access point and FreeBSD. When I got a new access point (a linksys) everything worked fine with wpa2 and I keep connecitons with no difficulties
