We are a family of seven in a 3000 square foot house, and there isn't a dead spot in the place. We use our WiFi on thirteen devices on a daily basis, and have not experienced lag or other difficulties with an overloaded WiFi system. It is easy to tinker with filter settings from the NETGEAR app. The model we own doesn't have all the filtering features we want, so we purchased a Disney Circle to pair with it, and have found it meets our needs. I understand that NETGEAR now sells a product that includes Disney Circle, which is wonderful for families looking to monitor electronic usage among family members. We strongly recommend NETGEAR to anyone wanting a reliable WiFi router.
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.
