If you're about to buy a new WiFi router anyway, I suggest that you go with the new "AX" (WiFi 6) standard.
The one you are considering is "AC" (WiFi 5) standard.
No one used to call it WiFi 5, but they do now.
What's the difference between 802.11ac vs. 802.11ax?
I have also read that when you go the mesh route, anything going through that mesh node, goes at half speed. That was not acceptable, so went with an ASUS AX-5400 and although it is twice the price, it seems to have very good range and looks like I'll be able to bypass any thoughts of mesh. I believe the increased range is due to the WiFi 6 standard. So far, so good.
