Reporting explains that home internet slowdowns in the evening are typically caused by congestion, as many nearby households and devices go online around the same time. Cable internet is especially affected because neighbors share bandwidth, while fiber connections are less prone to this issue. Suggested fixes include power-cycling modems and routers, and separating devices across different Wi-Fi frequency bands.
A tech advisory piece explains why home Wi-Fi speeds often fall short of advertised ISP speeds, citing interference, signal degradation through walls, and bandwidth overhead from multiple connected devices. It recommends using wired Ethernet connections for devices needing consistent high performance, while reserving Wi-Fi for mobile devices and smart home gadgets that lack Ethernet ports.
Many wireless peripherals, such as USB dongles for mice and keyboards, operate on the 2.4GHz radio frequency, a congested band also used by microwave ovens and older Wi-Fi gear. This overcrowding can interfere with Wi-Fi signals and slow down networks, especially for routers that are not running exclusively on the less crowded 5GHz or 6GHz bands used by Wi-Fi 6E and 7.
Despite the shift toward wireless devices, many high-end and gaming keyboards remain wired or offer no Bluetooth option at all, largely because of measurable input delay. Bluetooth connections introduce a few extra milliseconds of lag between a keypress and its registration on a computer, which barely matters for typing but can affect gaming or music production. A 2.4GHz USB dongle connection offers a faster alternative to Bluetooth, often approaching wired performance for latency-sensitive tasks.
Dual-band routers transmit Wi-Fi simultaneously on two frequencies, 2.4GHz and 5.0GHz, to spread device traffic across separate channels instead of one shared lane. The 2.4GHz band covers longer distances and passes through walls better but runs slower and gets crowded, while the 5.0GHz band delivers faster speeds and more capacity at the cost of range. Most modern routers automatically assign devices to whichever band suits them, though some networks still show separate SSIDs for each frequency.
