How to update the original version of bitcoin-qt

I have the original version of Bitcoin-qt but I can’t access my wallet so I’m trying to update. It’s been running for a few weeks, but when the internet goes out, the process starts again. Is there anyone in the Brisbane area who can help resolve this issue? Below are the details of the software

Bitcoin Core version v0.11.1 (32-bit)
