I have both of these routers atm.
I was using the DIR 655 as my main for a while and stopped using it in favor of the DGL 4500. I really haven't noticed an improvement in gaming with the DGL 4500. It is a good piece of hardware regardless of that.
That being said I am now being drawn back to the 655 for its securespot 2.0 feature. I have a 15 yo that likes to infect his computer on a regular basis...( yes somehow even with a decent AV package so I need effective parental controls).
I was thinking of somehow setting up the DGL 4500 downstairs to provide better range on my wireless network. But so far my research states I can't connect a wireless router to another wirelessly. I would need to do it via a LAN cable.
So I am back to the one router setup. Is the DGL really that much better than the DIR 655? My network consists of 3 laptops, a wii, PS3, xbox 360 and 3 desktops. I wouldn't say we are FPS nuts or anything.
If I didn't need securespot which is the better router?
