The Google Nest Pro Wifi Router is bad for wireless speeds. I think the
issue lies within the software firmware and heat dissipation of the
router. I changed my Google Fiber Jack which brought back some of the
speeds but did not fully resolve it till...
You are lucky to get 600-700 down next to the router. I only get
400-500mbps max. I do not have any mesh network either. I have a case
open with Google Support as well.
It was working perfect for like a month then they pushed out more
software updates and they broke the device. Wi-Fi 6E works great but
Wi-Fi 6 and prior are poor performance. I only have Wi-Fi 6E device so
it is frustrating experience.
