I have a SBG8300 on my first floor; the home is 3 floors/2700 sqft - the coverage inside the home is solid but if I step out to the deck the signal is very weak.
Want to add a Wi-Fi extender on the 3rd floor to improve connection/coverage but not sure what model/brand is compatible with my SBG8300.
Note: don’t think adding a mesh is possible, don’t have cable/Cat5 on third floor.
