Some users with the latest Wi-Fi 7-compatible smartphones and routers are finding their internet speeds slower than expected. This issue arises because many routers are set to default configurations that prioritize compatibility with older devices, rather than utilizing the full potential of Wi-Fi 7 technology. For example, users with high-speed fiber internet connections capable of up to 8 Gb/s and newer smartphones are only achieving around 800 Mb/s over Wi-Fi, which is far below the capabilities of their hardware. Wi-Fi 7 introduces several advancements, including the use of the 6 GHz frequency band and a feature called Multi-Link Operation (MLO). The 6 GHz band is faster and less crowded than older bands, and MLO allows devices to use multiple frequencies at the same time, combining their speeds and reducing delays. These features can significantly increase connection speeds, potentially exceeding 2 Gb/s for compatible devices. However, these capabilities are often disabled by default on routers. To take advantage of Wi-Fi 7's full potential, users must manually adjust their router settings. This involves accessing the router’s administration interface via a web browser or a dedicated app. Settings include enabling the 6 GHz band for client devices, setting the channel width to 320 MHz (the maximum available), activating MLO, and ensuring the network uses WPA3 security. Additionally, the router's hardware must support higher speeds, requiring at least a 2.5 Gb/s port and a category 6A cable to avoid limiting performance. Not all smartphones and routers are the same in terms of Wi-Fi 7 capabilities. Recent Android models, such as Samsung Galaxy S25 and S26, and Google Pixel 8, 9, and 10, can use the full 320 MHz channels and achieve speeds beyond 2.5 Gb/s. In contrast, newer iPhones, such as the 16 and 17 models, are limited to a 160 MHz channel width, resulting in speeds of around 1.5 to 1.8 Gb/s, regardless of MLO activation. Additionally, many Wi-Fi 7 routers in France are dual-band, operating only on 2.4 GHz and 5 GHz, without the 6 GHz band. These models cannot fully utilize MLO, as the 6 GHz band is required for the feature. Users are advised to check if their router is tri-band before attempting to unlock higher speeds.
