This is a used Google net Rounter. It works flawlessly. I am currently using exactly the same model as this Google WIFI Rounter for years and I haven't experienced any problem even blacked out electricity and it would automatically reconnected when electricity came back. This is a Google WIFI router and you just need one router like this if you have a normal house(not a very big) one and you might add up more Google WiFi points to create WiFi mash up to six when there's a very large house. If you need a very very strong wifi in your house from room to room, this is the wifi router you need.
