Homegroup designation problem.


New Member
Hello everyone! I am having a problem with homegroup.
I access internet by connecting to my home WiFi. However, everytime I restart my router, Windows recognise it as a new homegroup even though I change nothing in my router settings. I tried merging different homegroup together, but that didn't seem to work. Can anyone tell me what's the problem and how to correct it?
My system: Windows 7 Home Premium 64-bit
