"errors" : "WARNING: check your network connection,, 0 blocks received in the last 4 hours (96 expected)"

I am getting the following message “check your network connection…” (in more details below) and can’t see any mined coins even after hours of waiting each day and checking the internet. Please could anyone suggest how should I move further. Grateful for any solution/solution, with a request to kindly suggest a step-by-step approach in a simple language as I do not have technology background- if possible please. I am using an Ubuntu PC. Thanks.
