WLAN Device Issues with Poor Sensitivity USB Noise

August 14, 2019

Wireless LAN (WLAN) Internet connectivity is no longer restricted to smartphones and PCs, but is now also commonplace in home electrical equipment, such as TVs, Blu-ray recorders, etc. However, new electrical devices with built-in WLAN often suffer from connection problems due to various factors.
