You could easily spend hundreds of dollars on a high-end tri-band Wi-Fi 6E or Wi-Fi 7 mesh system. The box will promise you blanket multi-gigabit coverage across a 5,000-square-foot home; however, the real-world experience is plagued by weird and erratic wireless behavior. Your phone might desperately cling to a distant node instead of handing off cleanly, and download speeds in your office might spike, causing jitter and packet loss for someone gaming in the living room.
