I have an HP Pavilion 17-G199nr Touch screen laptop, running Linux mint 18, an HP G71-US340US Notebook, running Linux Mint 17, and a HP Envy 4652 All-in-One printer. Plenty of memory on both machines. I have a wifi router/internet modem, Verizon LTE4G - BRV 6700. I have set all of the permissions needed to share the appropriate folders on both machines. I have both Laptops and printer connected to it wirelessly. I have been able to network the printer to both machines but cannot connect either laptop to the other laptop. Not sure what else I need to do. Do I need to map anything? The wireless cards are both recognized and function in all other situations. Any help is appreciated. I am new to networking but fairly competent in Linux operation.

How are you trying to connect them?

thru the 6700 router wireless network. I open up my network and select connect to server enter the ip of the other computer and the address of the folder I want to connect to.

I assume you are using the The "Connect to Server" menu item in your file browser.

There should be a type selection box that contains several ways to connect i.e. ssh, ftp, Windows, WebDAV etc.

How you want to connect depends on what services need to be running on the other computer and I suggest using ssh. On the other computer make sure that ssh is running and that you configure the firewall if running to allow ssh traffic.

In addition to IP address and path enter the username and password of the other machine that has permissions to access the desired directory. The select connect.

Sorry, I haven't replied before now I have been undergoing 6 surgeries and totally ignored the network problem. Thanks for your help.
