WRT54G v3 & v4 -- difference in RAM? Firmware stability?

    Hello, I am new to Linksys wireless routers. I have an up and running Netgear wireless network, but it's kinda boring since there is no 3rd party firmware for it. Hence my interest in the WRT54G.

    After reading the warning about the WRT54G v5, I checked around town and found some v3 and v4 routers still available.

    I checked the router chart here at Linksysinfo.org and it indicates that v3 has 32MB RAM (16 used)/4MB Flash and v4 has 16MB RAM/4MB Flash.

    Does the difference in RAM really matter since the flash MB is the same? I am interested in playing around with 3rd party firmwares.

    I was leaning toward the WRT54G v4 since it is newer, but the difference in RAM makes me wonder which is better, or which one generally is more stable when it comes to flashing firmware.

    Thanks for your advice!

    Just like PC, more memory is always better isnt it?

    I suggest get the version 3.1

    All WRT54G units from v1 up to v4 have had 16MB RAM and 4 MB Flash - so the table on the Autopsy is wrong.

    The thing is all the WRT54G from v3 up to v4 use the same 1 pc Hynix HY5DU281622ET-J which are all (8MB x 16) = 16 MB chips so the 32MB figure quoted is NOT right.

    Hynix website: http://www.hynix.com/datasheet/eng/dram/details/dram_02_HY5DU281622ET.jsp

    Note that with WRT54G v4, the PCB has been redesigned with the Broadcom BCM5352EKPB which integrates CPU+MAC+EthernetSwitch on a chip, and matches the hardware of the WRT54GS v4 (which was downgraded from 32 MB RAM/8MB Flash to 16MB RAM / 8MB Flash).

    Thanks for all the replies.

    So does this mean that v4 is a better performer because of the hardware redesign, or not?

    Thanks again!

    Not necessarily. The wireless part seems the same. The CPU still runs at the same speed (216MHz with latest firmware).

    The redesign just means smaller PCB & less chips = cheaper to make, more profits.

    Thanks again; time to go shopping . . .
