I am running a Toshiba satellite pro laptop with Windows 7 home premium 32 bit and a Dell Inspiron with windows 7 home premium 64 bit and can't create a homegroup.
I started with "create homegroup' in Network and Sharing Centre and summarise steps as followed.
Your network connection must have IPv6 enabled
– start Homegroup troubleshooter
– troubleshoot network problems
– problems found with wireless adapter or access port
but it isn't fixed. Some help will be much appreciated.
