I just installed ElementaryOS and at first I wasn't able to get my wireless card working. Now after downloading the driver from "https://github.com/lwfinger/rtlwifi_new" and using make and install, I see my wireless adapter being detected. However, when I click on the WiFi icon, I can see "Wireless Network" immediately followed by disconnected. There isn't a list of available networks. I tried "iwlist wlan0 scan" but it comes up with no results. Help?
