    I believe you can find the answer on how to do this somewhere in the openwrt.org documents. Check it out here:


    PS: This came up a couple of weeks ago and it was stated that not all v2.2's have 32mb ram. You'll have to look at the motherboard of the router and see if there are 2 ram chips to be sure. This is as much as I know about this. I hope it helps, good luck!

    WRT54G v2 with ISSI IS42S16800A-7T

    First a warning: if you do this on the wrong router you will permanently brick it!

    Check if you have a wrt54gv2 unit with a IS42S16800A-7T memory chip. Unscrew and check!

    This IS42S16800A-7T memory chip means 32 Mbyte RAM, to enable it, you have to change the nvram variable sdram_init from 0x0000 to 0x0008.
