Windows 7: Homegroup Prob!

I have 2 laptops and a netbook all running Win 7. When trying to get them all to join the Homegroup it says there is no homegroup on this network? I have left the homegroup on 2 of the computers and created a new Homegroup on the third but it still says the same thing, any idea's what may be happening here? Thank you in advance for your help.

Why can’t I access my HomeGroup?



There are several reasons why you can’t access your HomeGroup. Here are the most popular reasons for not being able to connect to your HomeGroup.

• Your computer might not be connected to the network the HomeGroup is on. Make sure the computer has network/Internet access. Try having Windows 7 troubleshoot the Internet connection for you.
• Your network location might not be set to Home. Learn how to check and change your network location if needed.
• Network Discovery might be turned off. Learn how to turn Network Discovery back on.
• Other computers in the HomeGroup might be turned off.
• Other computer in the HomeGroup might not be sharing files. Learn how to share files using HomeGroup.
• Maybe someone changed the HomeGroup password. Try checking the HomeGroup password on other computers in the HomeGroup. If the HomeGroup password was changed, change the HomeGroup password on your computer.
• Your computer might not yet be joined to a HomeGroup. Learn how to join or create a HomeGroup.
• Turn off any third party firewalls (usually bundled with antivirus software) that are installed on your computer.

If none of these troubleshooting tips work, try restarting your computer, or leave and then re-join the HomeGroup.

All of that is said and done, and i went through the entire tutorial, it still isn't working. How do I find out if my wireless router supports ipv6?

It should be checked off here. You might also want to check your ipconfig /all to make sure there is a proper IPv6 address. The computer names also need to be different on all of your machines.

Sometimes putting the two services "homegroup listener" and "homegroup provider" to "automatic", helps with this problem.

Sometimes it works best to leave the Homegroup on all machines and reboot them all and start the Homegroup on another machine using all wired connections.

none of this has helped i'm sorry to say. I don't know what else to do because I don't have enough wire to do wired connections for them all.

Do you have any type of A/V software or third party firewalls installed on these machines?
