UPDATED after software fix 1.63.324946:Google customer service responds well to issues. Nest WiFi Pro 6E seems to work differently than my older mesh system and, although the speed and connection to my 2 wifi 6e devices was not what I expected to see, Google quickly opened a ticket and listened to customer concerns and issued an update. Speed tests seem erratic since it appears that this system allocates to different devices as needed. It seems as though it drops the speed (not the connection) when a device is idle to allocate the bandwidth to the ones currently in use. I’ve noticed that when I first log on to a pc, a speedtest may show a low reading but running it again after a couple of minutes of use shows the speed dramatically increased. My expectations for how this system worked were based on how my older system worked and I realized that being an early adopter of this new technology may mean encountering a few speed bumps. Google Nest, as well as my internet provider, will hopefully continue to make this system even better. As of now, all of my devices stay consistently online which was a big reason for my decision to upgrade. The 2 wifi 6e devices are the only ones that I think still need improvement and that may require better range for that band.Original Review:Google Nest WiFi Pro, Wi-Fi 6E, Reliable Home Wi-Fi System is what I got to replace the Google Nest three pack that I got six years ago and that has worked problem free the entire time.Three years ago I got the newer marshmallow shaped Google Nest router to replace the OnHub that was working with the three points and I really loved how well everything worked seamlessly.However, I have a smart home with a lot of devices in every room of a 3700 sq ft home as well as in the garage and front and back yard. I also have a Wifi 6e phone and Xfinity’s 1.2gb plan so I wanted to upgrade to something that would work more effectively with future devices. I am using the Xfinity XB8 combination modem and router device but I am using it only as a modem in bridge mode since it is not as efficient a router as this Google mesh system. The XB8 connected immediately with the Nest Wifi Pro and the combination works well.This upgrade only gives me three devices to replace the four from previous generations (router and three points) and I have these three in spots that I used before. The Google Home app mesh test shows great connection for all three.While I got this in anticipation of getting more Wifi 6E devices, the one thing that I have noticed is how much faster my smart home devices respond. Most of my other devices are also faster and I expect that will only increase as I upgrade them to Wifi6E as well as when Google Nest applies software upgrades which it does so well behind the scenes. The only possible negative that I can see is that the ethernet ports are only 1 gigabyte. This is not a problem for me at this time since multi-gigabyte tiers are not yet available in my area. I also rarely connect anything with ethernet since Wifi works so well.This upgrade works the same as previous generations with the Google Home app which allows very good control of the devices in one’s network. I am pleased with this upgrade and expect it to work as flawlessly as the previous generations have for the last six years, unless technology speeds up improvements before then and internet providers expand their tier. In that case, I will upgrade again with Google Nest Mesh since I like to stay with what works problem free for me.
