    Hello everybody!

    Its very bad that WPA2 takes a lot of speed from the 54 mbit. WPA2 takes so mutch, that i only reach 22mbit.

    So my question is, is there any way to increase the speed? Yes, i know disabling wpa2. But i mean another way?

    Thanks for your answer.

    Best regards

    Trying using AES and disabling TKIP. I don't know the Buffalo hardware, but the early Broadcom chipsets in the WRT54G/GS all did AES in hardware and TKIP in software.

    22 Mbps isn't actually that bad for 802.11g, best case is perhaps 24 Mbps. If both sides can handle frame bursting and 125 High Speed Mode (aka SpeedBooster aka Afterburner) and you don't have any other clients then you can get to around 26-27 Mbps best case.

    Thats bad, because i have already disabled TKIP and use AES. So i think i haven't any chance to get more speed :(
    But i didn't wan't to disable WPA2.

    The fastest is no encryption/disable security and wpa/wpa2+aes is the next fastest. Their is always overhead, and wireless companies adds it as speed. Encryption is mostlyl done in hardware (encryption). Anyhow, if you REALLY can't live without high wireless speeds, and must also use Tomato, why not tether one of the good draft-n dual-band routers you can get fairly cheaply nowadays. I've seen pci/mini-pci & mini-pci-express/expresscards that do not perform quite well, possibly because of poor antennas + power level, possibly noise within the computer also. Try connecting to your AP/WDS stations using another buffalo in client/client-bridge mode. This usually gives me the best rates that 802.11g can possibly give.

    good luck
