I am at my wits end. I have an old Gateway laptop running Mint 16. Intel Dual core T2060 @ 1.6 GHZ 2 GB RAM 120 GB SSD. This has been a fully functioning, reliable system ever since I upgraded to Mint (from Win 7).
Yesterday, I was doing some work with dd-wrt, so I turned off the WiFi and used the ethernet connection to tinker with a router. When I finished, I turned WiFi back on. Now I cannot connect to my WiFi!
I can see the SSID, I can click to connect to it, it looks like it is working to connect, but then never does.
Any help is appreciated, even a link to a step-by-step troubleshooting guide.
