I own a townhouse, and I want to set up a new network in my home. My plan is to use the Extreme as the router where cable modem is attached on the main floor and then set up a bridge on the 2nd floor to make sure I get full coverage to all the bedrooms. I need to have a strong signal on the 2nd floor because of all the other signals around my neighborhood, plus I am thinking of setting up an Apple TV in one of the bedrooms where I won't be able to run a ethernet cable to. I know many of my issues with the neighbors wireless signals will get better once I switch to N only, but my question is would the signal strength be just as good using an Express (n) upstairs as the bridge, or would it be beneficial to get another Extreme up there? Any suggestions would be appreciated!
