Split level, 1500 sqft house and this gives me great WiFi in every corner. Unit was very easy to setup, pretty much plug-n-play, though it was easy to access the web interface to change WiFi password, dhcp segment, etc. Works great with DSL and cable (I switched over to cable recently).
Bought this router used with the intention of testing it out to see if it had made a difference. And wow was I surprised at the improvement that this router had made! I would pay full price for this router if this one ever goes bad. Truly worth the purchase.
