So you have two networks. If you want all these to be on the same LAN, change the router to a WAP (hint: Google How to use a router as a WAP.)
I have a home network setup that I have been using for a while. With the purchase of new laptop to add to the network, I need to create a Homegroup. However, I can't see the homegroup I just created on the desktop from the new laptop. I have attached a diagram of my network if it will help in figuring out why I can't see it. I have another laptop that can't print to the wireless or wired printers either. I'm baffled. Any help would be great. Thanks.
