So I have the leased Arris gateway from Comcast, but there is some silly limitation of 5 IPs for the device. (Insane...I have 5 in my OFFICE ALONE!) I see 2 choices here, buy a nice gigabit router like the RT-N53U, or buy an all-in-one unit like the Zoom 5350. I am running a hard-wired Cat6 network, so wireless is not all that important to me. What would you do?
