Wired keyboards still beat Bluetooth on latency, 2.4GHz closes the gap

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 explained: how 2.4GHz and 5.0GHz Wi-Fi work together

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.
