Old Routers Secretly Slowing Your Internet

Many homes are unknowingly experiencing diminished broadband performance because their Wi-Fi routers are outdated. Research indicates that older Wi-Fi standards, such as Wi-Fi 4, maintain a significant presence globally, tethering hundreds of millions of users to hardware from the previous decade. This situation creates a bottleneck where modern devices operate below their potential due to obsolete residential equipment.

These legacy routers face limitations, particularly with signal congestion in older frequency bands. They are physically unable to access newer spectrum bands like 6 GHz, crucial for Wi-Fi 6E and Wi-Fi 7. This prevents users with new, capable smartphones from benefiting from the latest Wi-Fi technology when connected to an old router.

The issue is exacerbated as households simultaneously connect numerous devices like streaming TVs, gaming consoles, and smart appliances. Older Wi-Fi hardware was not engineered for such crowded digital environments, leading to reduced speeds, increased latency, and unstable connections. Even with advanced broadband plans, consumers may not receive the full value indoors because their routers cannot efficiently distribute higher speeds. For example, Wi-Fi 4 routers peak at 600 Mbps, far below the theoretical capabilities of Wi-Fi 7 which can reach 46 Gbps.
