Wifi issues, can't connect to networks, help

asked 2016-02-09 08:40:24 -0500

Cannot connect to wifi, happens regularly, on different wifi's. It just cannot seem to connect, when on home wifi, it allows me to connect and browse the internet for a bit, and then it will keep me connected to the wifi, but with no internet access! Any help would be much appreciated! CheerS

Can you please update your question with more information such as which WiFi card do you have? You can find out that information by listing out devices with lspci -v command.
