I have installed Ubuntu 14.04 on my Acer laptop alongside Windows 7.
Recently, I had to switch my modem/router, after it stopped working. I contacted my ISP's Tech Support and they send me a new device. So, I tried connecting to my WiFi with the new router, but its SSID is not on the list of the available networks. Windows 7 and other devices (Phone/Tablet) are able to find it and connect just fine. I am still able to connect with an ethernet cable.
I am relatively new to Ubuntu and after searching online for similar issues, I could not find a solution. Is this a driver issue? Would you have any suggestions?
