That looks like a network issue rather than an Access issue.
Access over a VPN will be about a reliable as a chocolate teapot I'm afraid unless you have at least a permanent 100Mb connection between the two end-points, and the machines are hard-wired.

If you have to use a VPN, then I would suggest a remote desktop solution, where the RDP sessions are hosted on the same network as the SQL server, speed will be great, and the quality of the connection between your SQL server and the end-users becomes much less critical.
