No, Even the Best Wi-Fi Extender Isn't Worth Your Time
Briefly

Wi-Fi extenders have functional limitations, often blocking outlets and requiring specific placement for optimal performance. Budget extenders perform poorly, while quality ones can be too expensive relative to routers and mesh systems. Alternatives include moving your router to a more central location, using Ethernet cables for superior speed, or investing in a new, modern router. Centralizing your router can enhance signal distribution, and for the best speeds, Ethernet connections are recommended whenever possible, although they may not suit all living situations.
Most Wi-Fi extenders are designed to plug directly into an outlet, limiting their placement options and often blocking adjacent outlets, which impacts performance.
Cheap Wi-Fi extenders perform poorly, making them hard to recommend, while better extenders are often too costly compared to routers and mesh systems.
Moving your router to a central location inside your home can significantly improve Wi-Fi performance, often more effectively than buying a new extender.
Using Ethernet cables provides the best solution for fast internet across the home, although it may not be ideal for renters.
