I've been using the latter for a couple of years now, and its flaws are really starting to bug me, in particular the fact that it hangs once a week. I've given up on waiting for Linksys to update the firmware, so I am looking for a replacement. I see the buzz about the "aftermarket" firmware available for the WRT54g, and that's cool. Even though my laptop (Dell 600m) can't benefit from the faster speed, I'm thinking of taking the plunge. So, is there anything that the BEFW11S4 can do that the WRT54G cannot? Thanks!
