I am just worried about using D-Link and Linksys gear for that type of a project ... There are three levels:
Home User Commercial Carrier
Linksys and D-Link are home user (some will likely not agree with me on that...). Can you use them? Sure! Will they work? Sure ... For a bit ...
We are an ISP and before I was hired they were using D-Link and Linksys5-port switches and diffferent locations ... Once I installed some CISCO switches our performance went up 500%+ -- just because it states speed X does not mean it is really that fast. I checked the data sheet for the Linksys 802.11n radio -- it only has 10/100Mbps ports ... So the maximum wired-to-wireless speed would be 200Mbps (upload = 100Mbps - download = 100Mbps).
