Merge or delete network locations

Today after installing a new Asus router which is a replacement for an old "G" version linksys everything seemed to be working as expected. I noticed that my network name showed up in a few area's with a 2 after the name. Reading some articles it seems that this is pretty common with win7 and not harmful but can be changed by removing the 2. The change was made but while doing it when you left click your network where you can change the name as well as icon, there is a button that says Merge or delete network locations. Its in this location where my question comes in. there are three connections listed the first being NB2-WXDL.test ....Managed. the next 2 are both the same which is my network name. The only thing different that I can see is the first is listed as not in use... unmanaged. the last one is showing in use... unmanaged. From searching the internet about this, it seems that the ones not being used can be safely deleted. I'm not one to do so blindly and wonder what your view is on this subject. Also as for the first network location name I have no idea what this is or how it got here. This laptop I bought new and have had it for 2 plus years.

Deleting a network that way is harmless. The only damage you can do is if you delete the one that's in use then you need to enter the network key again, same for the other networks.

Thank you for responding to my question. I took your advise and it worked like a charm.

No Problem, it'd be great if you can mark this as solved so people can skip by it when looking at posts :)
