Performance Breakdown

Speed & Throughput The AC1300 standard (up to 867 Mbps on 5GHz) is plenty for a home office setup. Post-update, the adapter handles 4K YouTube streaming without buffering. Transferring files from my NAS (Network Attached Storage) is now significantly snappier, averaging around 30-40 MB/s write speeds over WiFi, which is impressive for a USB 2.0 interface device.
