“Windows no longer detects a HomeGroup on this network. To create a new HomeGroup, click OK, then open HomeGroup in Control Panel.“ In most cases, this problem is seen after upgrading all of the computers on an already existing HomeGroup to Windows 10 with the HomeGroup still active. If a user affected by this problem click on OK and navigates to HomeGroup in the Control Panel, they are not provided with any option to create a new HomeGroup – they only see an option to join the already existing HomeGroup. It is always better to decommission an existing HomeGroup before upgrading all the computers on the HomeGroup to Windows 10, but not everyone is privy to this knowledge while upgrading. Thankfully, though, this problem can still be fixed post-Windows 10 upgrade, and the following are some of the absolute most effective solutions that a user affected by this issue can use to try and fix it:
Solution 1: Disable any and all antivirus and firewall programs on the affected computers
In many cases, what is preventing the affected computers from joining the existing HomeGroup in the first place can be something as trivial as an antivirus or firewall program – either stock or third-party. That being the case, the first possible solution any user affected by this specific issue should try is to disable any and all antivirus and firewall programs on every single one of the affected computers, and then try to have the computers join the HomeGroup. If you still see the “Windows no longer detects a HomeGroup on this network.” error message when trying to connect the affected computers to the HomeGroup, however, you should move on to some of the juicier solutions.
Solution 2: Leave the HomeGroup on the computer that created it and then create a new HomeGroup
Solution 3: Remove all traces of the old HomeGroup and create a new one
If neither of the solutions listed and described above worked for you or if you are simply not getting an option to quit or leave the old HomeGroup on the computer the old HomeGroup was created on, fear not – you still have one more shot at resolving this problem. Countless Windows 10 users who have been affected by this problem in the past have been able to resolve it by getting rid of every trace of the old HomeGroup and creating a new HomeGroup on a computer other than the one that was used to create the original HomeGroup.
