770: wireless speed issues

while playing around in my home network I noticed that wireless is kind of slow, I only have 1.5Mbit DSL so I didn't noticed it before. But now I tried to download stuff from my laptop via FTP and boy this sucks. I did a few tests with different security settings, since I use WPA and WPA is done in software, I though this could be the problem. Here are the results:

setup
    WRT54GS - with wrt-dd #22 prefinal4
    computer running Debian with proftpd (xinetd)
    N770 with Opera as ftp client
tests
    WPA-PSK TKIP+AES
    ftp ~80KB/s (cpu maxed out)

    WPA-PSK TKIP
    ftp ~150KB/s (cpu maxed out)

    WPA-PSK AES
    can't connect

    WEP 104bit
    ftp ~400KB/s (peek ~560KB/s)

    WEP 40bit
    same as for 104bit

    NONE
    same as for WEP

I didn't try WPA-EPA (radius). Also I noticed that the download destination also impacts the speed. When writing to memory I couldn't get more then 160KB/s, so all test downloads were done to MMC.
