Dunno le. You can check once the Starfug techs come to install the router. If they give you access to the router, can check if your older routers can mesh with it. Don't know if the $29.55 plan comes with that TP Link wifi 7 router + extender/access point. Anyway, all that is for later. First re-contract nia
If Starfug works okay for you, just re-contract that $29.55 plan.
$45-29.55 saves you 180 per year. If wifi signal at home is low at some spots, get 1-2 more access points and create mesh with the TP Link wifi 7 router they are going to give you. Liddat more worth it mah.
