Different boardflags than ddwrt, is that possible?

    Tomato has been a life saver. I couldn't get WDS to work properly with dd-wrt whatever I did. I have 8 Buffalo whr-hp-g54 routers linking buildings covering an area of a square mile. Two points have external amps (which I'll do away with considering the power output of the buffalo router) so I have to switch off the internal amps using nvram set boardflags options. dd-wrt doesn't have the options in the menus so I telnet in and do it.

    Here is the settings that dd-wrt uses.
    http://www.dd-wrt.com/wiki/index.php/WHR-HP-G54

    0x0758 - no amp and receive sensitivity normal
    0x1758 - enhanced receive sensitivity
    0x2758 - amp on, normal receive
    0x3758 - both amp and BroadRange enhanced receive sensitivity on

    Now in Tomato 1.21 I have a menu that I can enable or disable the tx amp and rx amps. I then telnet in and do a nvram get boardflags to see what it set it to.

    0x0758 - enhanced receive sensitivity
    0x1758 - no amp and receive sensitivity normal
    0x2758 - both amp and BroadRange enhanced receive sensitivity on
    0x3758 - amp on, normal receive

    I can confirm that these settings work like this. with 0x3758 - amp on, normal receive I get rx signal of -57dbm and with 0x2758 - both amp and BroadRange enhanced receive sensitivity on I get rx signal of -45dbm. Also the default setting Tomato installed with was 0x2758 which is optimal. The default that dd-wrt v24 installs is 0x3758 which seem optimal there.

    I guess I thought boardflags were a hardware switch and couldn't be different from firmware to firmware. Perhaps it's in the wifi drivers. Can anyone explain?

    I think dd-wrt has it backwards. I find that for me 0x2758 works better in dd-wrt just as it works better in Tomato.

    Do you still find that 0x2758 works better for you as of the latest Tomato versions (1.24/1.25) ? Because in the GUI, setting the default value (enhance Rx) makes Boardflags=0x3758 which would contradict what you are saying.
