R3000Z ndis0 54Mbps?

[Joshua]

Hi folks, trying to set my wireless card (the broadcom) to 54mbps. I
have been noticing that my connection is ridiculously slow since
installing freebsd. Right now my ifconfig looks like this (note the
1Mbps): 

        ndis0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu
        1500
        inet6 fe80::290:4bff:fe61:dcdb%ndis0 prefixlen 64 scopeid 0x4
        inet 192.168.0.3 netmask 0xffffff00 broadcast 192.168.0.255
        ether 00:90:4b:61:dc:db

        (DS/1Mbps)

Thanks!
