Item Description

The Premiertek PT-8811AU is a compact USB wireless adapter that brings fast connectivity to your desktop or laptop. It supports the 802.11a/b/g/n/ac standards across both 2.4GHz and 5GHz bands, giving you flexibility in choosing the right frequency for your needs. The Realtek RTL8811AU chipset delivers transfer speeds up to 433Mbps when using 80MHz bandwidth, though you'll also get solid performance at 150Mbps with 40MHz bandwidth or 72.2Mbps with standard 20MHz channels. This adapter handles modern security well, supporting WEP, WPA, and WPA2 encryption with both TKIP and AES protocols. The physical footprint is tiny at just 1.18 inches long, 0.58 inches wide, and 0.3 inches tall, so it won't block adjacent USB ports or take up much space. It connects via USB 2.0, which is standard on virtually every computer made in the last decade. The PT-8811AU uses advanced modulation schemes including BPSK, QPSK, 16QAM, 64QAM, and 256QAM to optimize signal quality depending on your distance from the router. It's certified for CE, FCC, RoHS, and REACH compliance, meaning it meets safety and environmental standards across multiple regions. Whether you're adding wireless capability to an older machine or upgrading from an older adapter, this Premiertek unit offers straightforward installation and reliable performance for everyday browsing, streaming, and work tasks.
