Constrained by the maximum throughput limits of USB 2.0 technology.
Potential workarounds included forcing the adapter to use the more stable but slower 802.11g standard (with a maximum of 54 Mbps) or the older 802.11b standard (with a maximum of 11 Mbps). While this reduces raw throughput, it eliminates dropouts, which is crucial for latency-sensitive applications like gaming or VoIP.
