I am running on a G3 powerbook b&w with 65 mb of virtual memory and 64mb of built in memory (way to low, i know) i have allocated 3048k ram to LW. I have no firewalls that im aware of(I just barely got my computer back from a friend of mine who updated my os and I dont know how to check my firewalls) I have a dsl connection and my modem is a westell 2200. My router is from Melkin, i dont know the model #, sorry. And I am connecting from home.
