Just upgraded to v 4 last week. It takes 20 sec to load up demographics or other aplets on AC.
One tech said that speed test suggests bandwidth. Doesn't make sense, as I spoke to linksys and uploaded latest software for wrt54g, and it still runs slow on all 4 of the 5 terminals we have hooked up to the main computer.
RAM issue? Although one site on AC said only 245 K ram needed, on the V4 download it said minimum of 1 G ram. I don't know who is right, I am guessing that 1 G or more is likely the problem. What's odd, is that one terminal with 1 G is running slow, yet the only terminal that runs fast has only 500 K RAM. The rest have between 256 and 500 K.
Is it software? While installing, most of the terminals said something to the effect "missing file ... SGL something...". So I am not sure if all the components are installed.
2 tech support has not been helpful. They said to get a network guy to figure it out.
I am guessing that it is a RAM issue. I am surprised that they have not updated their requirement or make it clear. Why on one site they said at least 1G, and another (the one with the diagrams and said that "any computers sold should more than satisfy" the 256K requirement.
I think I am going to upgrade RAM on one of them first, and see what happens. Then, I'll worry about changing the WRT54G router.
