My modem and D-Link DIR-855 were damaged from lightning today, so I am looking to get a new router. I have a fairly large 2 story house that I would need to cover. The two main options I'm looking at are 1. Getting another DIR-855 or 2. Getting a Linksys E4200. The DIR-855 had the range to cover most of the house, but lacked signal in the far ends. Would the E4200 do any better as far as speed and range? Also how do they compare in terms of durability?
