I picked up one of these so that my wifi would reach my garage and I haven't had any problems out of it. It doesn't force you to make a separate wifi network with this one either, which is one of the reasons that I bought. Set up is simple (roughly 15 minutes w/ testing), and it supports both 2.4ghz and 5ghz.

Wifi extenders work, but are not as good as Mesh wifi system, If you want a here buy this for under $50 option get one of these: https://smile.amazon.com/gp/product/B010S6SG3S/ and plug it in within about 30 feet of your Starlink router, set it up as a wifi extender and then set your devices to connect to it.

This would be a good solution if for example your Starlink router is at one end of your house, and you get little or no wifi signal from it at the other end of your house. Simply install this near the middle of the house, or perhaps a little closer to the Starlink router, so you will then get wifi signal over a larger portion of the house from one source or the other.
