Hi. I am currently using FreeBSD 7.2-RELEASE. I have a problem with
wireless networks. I am using FreeBSD as an access point with wpa
encryption. Almost %30 packets are loses when I ping the ap. It's very
painfully to use ssh connection with this ap. Do you have any idea about
packet loses?
My adapter is Edimax 7128. My ping result from a Linux machine:
$ ping 192.168.1.1
