Frequently asked questions
Will a higher-gain antenna improve my Wi-Fi?
A higher-gain antenna can extend range in a specific direction, which helps for point-to-point links or reaching a distant room. It won't create signal where there is none, and very high-gain antennas narrow the coverage area, so match the type to your layout.
Are replacement router antennas compatible with my device?
Most external router and access point aerials use a standard RP-SMA connector, but you should confirm the connector type and whether your device's antennas are removable before buying. 4G/LTE and FM/DAB aerials use different connectors again.
