Running Ubuntu 14.04 on a custom build. I have Encore wireless N300 PCI-E Adapter ( seen here ) The driver is available for download at this link as well. I am reading that a common fix for connection issues is to uninstall/reinstall the wireless driver. But before I jump the gun, I wonder if there is some other things I should look at first? Also, once downloaded, how do I install? It only drops connection for a second, and then re connects. The problem is, I lose my VPN connection and it then reconnects clean. (WiFi drops regardless of vpn or open)Note: I also have this posted for a few days in Ubuntuforums, but I've gotten no response yet.lspciNetwork controller: Realtek Semiconductor Co., Ltd.
