Well settings are great, sad thing is even though I'm knowledgeable enough to configure them I never even bothered to configure my DGL-4100.
While I haven't been in need of a wireless network in the past, I might consider using it in the future which is why I was thinking of getting the LINKSYS WRT54GL instead of getting another DGL-4100. I know there is a DGL-4300 and a DGL-4500 that have wireless capability, but as I mentioned before I haven't bothered to take advantage of all the features that the DGL routers are capable of.
