Wi-Fi speed issues may stem from outdated 802.11b settings

Slow Wi-Fi performance may be caused by outdated router settings, specifically the continued support for the 802.11b standard. Introduced in 1999, this technology operates on the 2.4 GHz frequency and allows for very low data transfer speeds, as low as 1 Mbps.

Because Wi-Fi devices on the same channel share available communication time, slower devices can congest the radio frequency space. While manufacturers often keep this standard active to ensure compatibility with older hardware, most modern devices no longer require it. Disabling or adjusting this setting can free up capacity on the 2.4 GHz band, allowing newer devices to operate more efficiently.

On advanced router models from manufacturers such as TP-Link, Netgear, or Asus, users may be able to increase the minimum data transfer rate. Instead of allowing speeds as low as 1 Mbps, users can set a higher minimum, such as 6 or 12 Mbps, through settings typically labeled as Wireless Mode or Wi-Fi Mode.
