Langaton USB-adapteri QOLTEC 56988 Dual Band 1300Mbps USB 3.0

QOLTEC 56988 is a wireless USB adapter that provides Dual Band connectivity over 2.4 GHz and 5 GHz with combined throughput up to 1300 Mbps via a USB 3.0 interface. Designed to add wireless capability to laptops or desktop PCs that lack built‑in Wi‑Fi or to replace an older adapter, it enables higher transfer speeds and more stable connections for bandwidth‑intensive activities. The compact external form factor and USB 3.0 connection make it compatible with a wide range of modern systems while supporting common Wi‑Fi network modes.

Advantages

The Dual Band design reduces interference by allowing devices to use the less congested 5 GHz band for high‑speed tasks while retaining 2.4 GHz compatibility for longer range and legacy devices. USB 3.0 connectivity ensures the adapter can reach its maximum throughput on compatible ports, improving performance for streaming, online gaming and large file transfers. The plug‑and‑play nature simplifies installation on most systems and the external USB form factor offers easy placement and replacement without opening the computer chassis.

Suitable for

• Upgrading older laptops or desktops to modern Dual Band Wi‑Fi
• High‑definition video streaming and video calls
• Online gaming where lower latency and stable throughput are important
• Fast downloading and uploading of large files
• Temporary or portable network upgrades when using multiple devices

Key specifications

• Wireless bands: 2.4 GHz and 5 GHz (Dual Band)
• Maximum wireless throughput: up to 1300 Mbps
• Interface: USB 3.0
• Form factor: external USB adapter
• Compatible network modes: IEEE 802.11 standards (backward compatible)

How to use

Insert the adapter into an available USB 3.0 port on the computer. Allow the operating system to detect the device and install drivers automatically where supported, or install drivers provided by the vendor if required. After the adapter is recognized, select the appropriate Wi‑Fi network and enter the network security credentials. For best throughput, connect to a 5 GHz network when available and ensure the USB port supports USB 3.0 to avoid bandwidth limitations.

Recommendations

Place the adapter in an unobstructed USB port and avoid locations with heavy RF interference. Use 5 GHz for latency‑sensitive tasks and 2.4 GHz for greater range. Keep drivers updated and connect to a USB 3.0 port to achieve the claimed performance.
