I have a Daedalus wallett ver. 0.13.1
what do I need to do to upgrade because it is not synching with new network
Yep, you’ll need to update it – we’re currently at 0.15.1.
You can find the latest version at https://daedaluswallet.io.
Simply installing it over the old version should do the trick.
great, that will not effect the ADA the wallet is holding will it ?
just make sure you got your seed somewhere safely.
if you got that, you dont have any problems for sure 
No, your funds will still be there.
Even in the absolute worst case (=Daedalus losing your wallet data in the update process) you’d simply have to restore the wallet using your recovery phrase. Your ADA live on the blockchain, not inside Daedalus.
