I just noticed this section on Google WiFi. I have been making comments on both Google WiFi and Google Home over in the mobile phone space, thinking that most of you read that space for things phone related. I am in the process of setting up a smart home, having already purchased a Nest Thermostat (great experience to date) and Chromecast TV stick and soon to buy the Philips Hue lightbulbs. I expect to purchase a couple of Google Home devices soon too. One will test my kitchen WiFi, two rooms away from the current Virgin Media router. The kitchen has been a WiFi problem in the past however.
Anyway, like Jimlad I have many WiFi dead spots in the house largely due to brick walls and the concept of a mesh network with each Google WiFi "puck" (seems these round devices are nick-named "pucks") itself being a router (rather than an extender) to create the mesh network seems the way to go. I am only torn between how many pucks I will need to buy--at least two.
So I spoke to Google Customer Service about the technical specs, etc and learned a few things:
1. Google WiFi, sold individually or in packs of two pucks, are free standing routers. One must be attached to my Virgin combined modem/router hub (I believe Jimlad has the same hub). The Virgin router portion will then be replaced by the Google WiFi router leaving the Virgin hub as a modem only. For some homes, one puck will be enough but I described my home and WiFi problem and they suggested two pucks to start, separated by one or two rooms.
2. The Google WiFi app in the Play Store walks you through the set-up starting by identifying the first puck (if you are using two or more pucks) and this first puck is the one that takes over the first port in the back of the Virgin hub, moving the existing Virgin router to another slot before it is inactivated in effect by the primacy of Google WiFi. Once the Google WiFi app identifies the first puck, you create a name for it and a password to activate before setting up the second puck say two rooms away. The app also helps you locate the second puck for ideal performance. It seems it is really simple to set up.
Bottom line: I plan to purchase the two pack of pucks and see if that meets my needs before expanding say to a third puck.
I did notice this article from Stuff which gives a hands-on review of Google WiFi. I find some of the benefits also mentioned to be useful: being able to share password to a guests phone for example, the more efficient use of WiFi that prioritises one device over another, etc. The author mentions some of the competing products like Netgear Orbi, Ubiquiti Amplify and Eero. The author sees Google WiFi as the best looking and most user-friendly seen so far.
