I too have a G1100 FIOS router and may have stupidly let the Verizon techs talk me into getting the WiFi 6 service for only $8 more per month. My question is - I have a Linksys AC level extender to get signal to the back rooms of the house. Will we notice better speeds per device if I upgrade to a WiFi 6 enabled extender?
