A slow wireless Internet network (Wi-Fi) does not require immediate replacement of the router, as some simple software and infrastructure modifications can increase the efficiency of the network and extend the life of the device.
At the top of the list of proposed solutions is the necessity of changing the Wi-Fi channel, especially on the 2.4 GHz band, to avoid interference resulting from congestion of surrounding networks, as moving to a channel with less pressure contributes to enhancing the stability of the connection. If the router supports the 5 GHz band, it is preferable to direct it to nearby devices to benefit from higher speeds and less interference, while the 2.4 GHz band is allocated to distant devices due to its superior ability to penetrate walls.
In the technical context, the role of updating the router’s firmware in improving performance and security level and addressing technical vulnerabilities is highlighted, in addition to the importance of rebooting the device periodically to fix temporary malfunctions resulting from continuous operation.
Preventive measures also include reviewing the list of connected devices and updating the password to exclude any intrusive devices that reduce the burden on the network, as well as adjusting the Domain Name Servers (DNS) settings to reduce response time when browsing websites, regardless of the original Internet speed.
Regarding placement and equipment, the instructions stress that poor coverage may result from placing the router inside closed cabinets, behind thick walls, or near sources of interference, and if the slowness continues despite exhausting these steps, replacing or relocating the device becomes inevitable.
