How do I solve an unidentified network issue? It can’t connect to the Internet

I basically have a problem with Windows 7 connecting to my home network.

It keeps identifying my home network as unidentified, and it continually does “identifying” until it simply say cannot connect to the Internet. I don’t know how this problem occurred. It simply happened one morning.

I am running Windows 7 Ultimate. I have a Realtek Network adapter. I don’t think it’s the drivers. I have already tried a system restore to a date when my computer was working fine, but it still didn’t fix the problem. From what I’ve read online there was this bug in the services.msc area, something to do with Bonjour service. I cannot find either so I do not think that was the problem.

I’ll be online for a while, so I can provide any additional details if needed.

I don’t really know how to explain it, because it’s so fudging complicated. I really appreciate clear and open steps to solving this. I have tried some things like system restore and rolling back drivers, and it doesn’t seem to help.
