I have 3 computers, all with Windows 7 on them; a main desktop computer and 2 laptops. The main computer is connected to the internet via a hard connection from my router, which also connects to the printer. I set up a wireless network on the main computer using a Linksys router. The computer automatically named to network "Network 2" because I had upgraded from a slower router. I named the network "OurNet" but what the computer shows is "Network 2". The laptops have been set up to see "OurNet" as well and show that when I look at network connections. When I try to set up the home network so I can share files and the printer between my main computer and the two laptops, the laptops can't see the main computer or the printer, even though they're both running Windows 7. If I set up the home network on one of the laptops, the second laptop has no trouble seeing the first one. But neither can see the main computer. I've tried to rename the main computer's network name but have been unable to. What can I do to successfully create a home network for my 3 computers? Before I upgraded my router, it all worked fine. Now it doesn't.
