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!
