I have just upgraded my 5 pc's (1 HP AIO, 1 custom EVGA rig, 1 Dell, and 2 HP 4440s laptops) to 8.1 Pro 64 bit. They are all updated and use the same server for system time (time.windows.com) and are all synchronized. I cannot, for the life of me, get any of them to connect to the PC I've created the Homegroup on (EVGA rig-hardwired).  I have an Westell (Netgear) 7550 that I believe is the source of the problem. When any of the PC's are hardwired to the modem/router, they do not recognize the created Homegroup but when I disconnect the LAN and go wireless on any of the machines, they recognize the created Homegroup on EVGA but will not connect. 

run this basic troubleshooting regarding Homegroup in Windows 8.1 and share the result here

http://windows.microsoft.com/en-us/windows-8/homegroup-problems-in-windows

this is the checkpoints

1. You might have a Windows operating system that restricts your homegroup use
2. You might not be connected to a network, or you might not be connected to the right network.
3. "Find devices and content" might be turned off.
4. Date and time might be incorrect.
5. Two or more PCs on the network might have the same name.
6. The other PCs in your homegroup might not be in the home, might have left the homegroup, or might be turned off, sleeping, or hibernating.
7. Network discovery might be turned off.
8. Your system administrator might have turned off HomeGroup.
9. One or more required services might not be running.
10. IPv6 might be disabled.
11. The peer networking idstore.sst file might be damaged.
12. Your PC already belongs to a homegroup.
13. Other unknown problems.

good luck

I get an error saying that the problem is network related.

This is as far as I can get with the troubleshooter. Everything else that MS gives as a possible fix is useless and completely incorrect..... as usual.

P.S. How can I get my account verified so I can post a screenshot?
