I recently ditched my Google Nest. It was driving me up the wall with inconsistent performance and wifi signal was reduced to a miserable 2%, which made it impossible for all my devices to connect. I rely on my wifi at home a lot because I make my living on it. So a stable and high performing wifi is crucial for me.
I decided to replace my Google Nest with the RBK752. Initially I thought just 1 Satellite would be sufficient. But alas, I discovered it too suffer from a similar shortcoming as the Google Nest - the signals had problems penetrating the thick concrete walls in my apartment. I tried living with 1 Satellite for a few days but it didn't quite work for me. So I had to fork out another $379 for another Satellite.
The 2nd Satellite fortunately resolved the weak wifi signals, and now at least I'm enjoying a pretty consistent speeds of 200+/300+ Mbps from all my rooms. The consistent speeds are probably due to the dedicated backhaul channel.
All good for now.
I had high hopes before I purchased the RBK752, however those high hopes have now been tempered.
Hopefully the RBK752 will provide this level of connectivity for the next few years - or at least outlast the Google Nest which lasted about 2 years.
