Internet Connection

Hi can anyone help please, I have Raspberry pi 7.o which has been working great till last might . When it stopped noticed the Date was wrong , which I know means No Internet Connection. Spent nearly 5 hours trying to find the “openlec page” finally found it, tried to connect to internet wasn’t having it, when tried to connect it just kept saying ” Network fail aborted ” Finally went to Bed , this Morning back to trying again . Now I have managed to get connected to the Net & it’s showing that it’s there & it’s Status is Ready, so I have Rebooted , Power off & all that has Happened is the Date has gone from May 2016 to January 2017 but still not working . Would be Grateful for any HELP Please
