Working with Acer Vireless LAN (function () {('review-page-page-desktop');}); Acer Ralink Vireless LAN Card is a free official utility software and tool. The software driver is designed to work with an Acers wireless LAN card. A wireless LAN card is an external device used to connect to a local wireless network for computers or laptops. Sometimes they do not have an integrated network to connect the device, or they need additional amplification for the network connection. There will also be cases where computers or laptops cannot read wireless LAN cards as expected. They may need an updated driver so that computers and laptops can easily identify and use them. Users simply open their device manager, update the driver and open it.
