I have three win 7 PCs. I have one teracom BSNL Broadband 4 port router modem. I can share internet easily but cannot share the files and printers from one another. Please help.
You'd want all the computers part of the same homegroup. Take one main computer, type in homegroup in the search field and setup a new one. Then do the same search on the other two computers and join to the homegroup you created. You'll be able to share anything you want between them.
