Manual Wi-Fi Channel Switch Fixes Years of Slow Internet Across 2 Bands

Summary
A manual router channel change cleared up years of sluggish internet after the user found the connection was bottlenecked by Wi-Fi interference, not the broadband plan or ISP.
11 channels exist on 2.4GHz in most countries, but only 1, 6 and 11 avoid overlap; in crowded buildings, multiple nearby routers often pile onto the same spectrum and slow each other down.
A Wi-Fi analyzer app mapped nearby networks and highlighted less congested channels on both 2.4GHz and 5GHz, letting the user pick cleaner options in a few minutes through the router’s admin panel.
Auto channel selection often fails because many routers choose a channel only at boot, so the fix may need occasional rescanning as neighbors’ networks shift.
Other router tweaks can still matter, including QoS, faster third-party DNS, firmware updates and better router placement before paying for a higher-speed plan.
