Works with 2.4 GHz and 5 GHz bands
One of the main features of the model TP-Link Archer T2U is the support of two frequency ranges. Range 2.4 GHz It has better penetration through walls and ceilings, but is often overloaded with signals from household appliances and neighbors' routers. Speeds in this range are typically lower, but the coverage area is wider.
Range 5 GHz Provides significantly higher data transfer rates and is less susceptible to interference, but has a shorter range. To operate in this mode, your router must also broadcast the 802.11ac network. The adapter will automatically prefer the 5 GHz network, all other conditions being equal, if the driver is configured correctly.
Switching between bands can be forced in the adapter settings. In the Device Manager, under Properties Wireless Adapter, the "Advanced" tab often has a "Preferred Band" option. By setting the value Prefer 5GHz band, you will force your computer to ignore slow 2.4 GHz networks if a fast network is available.
