All was working fine about 2 months ago, Then I changed IP from a cable connection (roadrunner LIGHT) to Open range 4G system. My vonage device had trouble with open range and was very choppy most of the time. So I switched back to roadrunner (this time it's turbo - 15mb) I'm not sure that during the brief period of having open range if the computers could see each other. It could be that we never needed them too so I never looked into it.
So I watched a youtube video for setting up a home group when I discovered the problem. Everything is setup right as far as I can tell. Workgroup name is the same and each computer has it's own name.

Details;
main pc is a DESKTOP hardwired to internet running windows 7
then one laptop running Vista and another running XP
Both laptops have a strong signal and we can surf the net without issue on both of them.
But the main PC (desktop) doesn't see the laptops at all.
I want to be able to share files and print from the laptops as I was able to do prior to my switching internet providers.

Thanks in advance for any input.10 views but no replies? C'mon somebody has to have something.Did you setup your file sharing,printers before on these computers? Make sure everything is turn on for Network discovery and File sharing, and you must check if they belong to the same Workgroup. See here on how to set your Network again. http://www.howtogeek.com/howto/windows-7/share-files-and-printers-between-windows-7-and-xp/Well I gave up and called my computer repair man. He discovered that it is grabbing the wrong IP address. Trouble is that he can't figure out why. So the problem still exists, but at least I know why. Unless someone here has another suggestion I'm taking the tower in to him tomorrow.I was thinking that in between switching internet providers made certain IP addressing conflict from Dynamic to Static as required to VOIP while using File sharing as simply using Automatic IP and DNS can be obtained. Depending on how you have your ISP network setup,settings plus additional devices such as Vonage which requires a default IP address and Printer for network sharing, the TCP/IP for your LAN/WLAN ADAPTER properties will clearly give you as to what settings you are currently running.Ok, so what you gave me only makes a little sense to me, I'm just not well versed enough to UNDERSTAND everything you said.
I took the computer in to have it looked at and he tried something, but it didn't work, he needs to come out to my house and work on it where my network is at in order to fix it.
I'll show him this THREAD.
