Page name URL

https://www.lifestreamz.com – I am hosting at Network Solutions. My home page url is fine – however all subsequent pages, when accessed, are appearing at page names not mapped back to my domain. For example the “About” page appears at https://030c7c0.netsolhost.com/WordPress/?page_id=2 I’ve emailed Network Solutions tech support and they are absolutely useless in resolving this issue. Is there a setting in WP admin that needs to change? Or is this something at the server configuration for this installation and if so could someone please advise exactly what the issue is so I can relate to Network Solutions “tech support”.

Thanks
