Question

Each time I try to order a book, it says "network connection not available". Any tips to troubleshoot?

Answer 1

As the error message says, you computer cannot connect to the network.
It is difficult for us to give advice since we do not know your network setup. Try the network diagnostics utility:
     Open System Preferences -> Network ;
At the bottom of the window is a button labelled "Assist me", press it, then in the drop down panel press "Diagnostics" and inspect your network status.
