Fun with WDS and WPA/WPA2/TKIP/AES

    I'm getting ready to replace an elderly primary WRT54GL with an ASUS RT-N16 - the primary connects to several secondary WRT54GL's via AP+WDS. Current security is WPA/WPA2 Personal +AES on all routers, works great.

    New primary RT-N16 is running Toastman 7493 Std, secondaries are Toastman 7625 std. In my test environment, I can only get them to connect with one of the following :

    1. Security disabled
    2. WPA + TKIP on both
    3. WPA + TKIP on primary, WPA/WPA2 + TKIP on secondary
    4. WPA + TKIP/AES on primary, WPA + TKIP/AES on secondary

    From my limited knowledge of the subject, I thought AES was the standard for newer hardware, but it looks like the RT-N16 doesn't support it, because the only working combinations require TKIP - all AES-only configurations fail to connect.

    Reconfiguring the secondaries will be a RPITA, which I'd like to avoid if at all possible.

    Suggestions welcome.

    WPA2 and AES works must use for N-standard

    I use WPA AES just fine with N.

    OK, I've flashed the RT-N16 with tomato-K26-1.28.0493MIPSR2-Toastman-RT-N-Std.trx and found a working AES combination :

    Main : WPA Personal + AES
    Secondary : WPA/WPA2 Personal +AES <--- This means I won't have to change any secondaries :)

    So far I haven't found any successful combination which includes WPA2 on the main.
    I also turned off WMM although I haven't a clue what that does - lots more research to do ;)

    Thanks Haddock & Middleton - you guys rock!
