I am completely new to Linux. I just installed the newest version of Linux Mint: Cinnamon Serena 18.1, to two laptops that were having issues. One is an old Toshiba Satellite L305, the other a newer HP Stream Netbook PC 13. They both seem to be working fine except that they cannot connect to wifi. I can view wifi connections, but after entering the password, they don't connect. I can't find many resources for the newest version, but I read that, because it's so new, it still has some bugs. Is this one of them? I appreciate any help!
