When I unpacked and start to set up I had trouble connecting to my ISP. On the primary base station there is a soft reset button underneath, pushed that and waited for the light to go red, it rebooted and then presto it worked! Easy set up, follow the set up guide in the app, you put each wifi point out and turn it on the app finds it and tests the signal strength. The advanced eero package you can trial for a month with add blockers and threat identification is pretty good. Costs about $3 a month after that. All in all very happy with it, works well, the kids devices are all set up under their own profile so easier to manage, you can turn on band steering as well which works well. Excellent product and worth the investment, I had an old model supplied by my ISP it wasn't great, this one is brilliant.
