Hello @Ozman5
Nest WiFi Pro would include a few improvements. One, it supports WiFi 6, a newer set of standards that enable some higher speeds on the 2.4GHz and 5GHz band. Your existing WiFi 6 devices might be able to take advantage of these improvements, though I would caution that the improvements are mostly applicable at very short ranges (in the same room as the access point without obstructions between it and the client in question). The second improvement is the addition of a 6GHz radio. This enables WiFi 6E devices (WiFi 6 running on the 6GHz band) to access the network. It also is where the mesh interconnect has been moved (in the current products, the mesh interconnect runs on the 5GHz radio). So, the Nest WiFi Pro is not a true "tri-band" mesh system.
However, Nest WiFi Pro is currently limited to a lower transmit power in the 6GHz band, though a higher transmit power feature is coming soon. With the lower transmit power, you may find you have to place the mesh/secondary units a bit closer to the primary to get a "great" mesh test.
So, with all of that as context, will it improve your speeds? That depends (sorry). Are your WiFi devices currently able to take advantage of your 300Mbps internet connection today, using your current WiFi solution? Keep in mind that things like streaming TVs and gaming consoles have notoriously bad WiFi implementations, so upgrading your WiFi network may not improve their performance, even if they are ostensibly "WiFi 6" capable. Connecting them via Ethernet is often the best solution. So, the answer to your question is "maybe". I am still running my original Google WiFi system, and it is still working great for me. So, I have not invested in the new Nest WiFi Pro network myself. But, I also have a wired Ethernet network in place, so anything performance-sensitive is connected that way instead of via WiFi. I guess I could only advise that if you are having performance or coverage problems today, try to understand what the source of those issues actually is – swapping systems may or may not solve them. But, if you aren't having issues today, why not keep using your current system as long as it continues to perform well enough for you?
