I have been using Mint 17 for the past 2 months now and it didn't show any problem in networking. Recently, however, when I connect to WiFi it works fine for a while, but when I leave the system idle even for a few seconds, the internet goes down but the wifi is still connected.The browser shows the error DNS_PROBE_FINISHED_NO_INTERNET and I have changed the DNS to 8.8.8.8 and 8.8.4.4 but the problem still won't budge. If I disconnect and connect again, it will work fine but onlly until the next time I leave it idle.
