Optimizing Google Mesh WiFi with ATT Fiber BGW320-500
I am not getting the WiFi signal strength I should given my infrastructure. Home is 3600 sq ft, fiber comes in at NW corner in basement to BGW320-500. I have four Google Mesh units spread over all three levels, using a the same SSID/PWD on the fiber modem and Mesh units.
1. Basement unit connected via LAN through 1 gigabit switch back to fiber modem, located on N outer edge of home 50' from fiber modem.
2. First floor (Office) unit connect to via LAN through 2 switches
3. First floor unit on SE corner of house w/ WAN connection with 'Good' signal (according to Google).
4. Second floor unit on NW corner of house with w/ WAN connection 'Good' signal (according to Google).
If I am standing within a few feet of the WAN connections I get about 75-80 Mbps.
Is there a better way to configure the fiber modem? Passthrough? something else?
Thanks in advance.
