WRT 1900AC and Windows 7 network naming question(s)

Question

Background:  I had a Linksys E3000 up and running for about 5 years in a stable network environment.  The E3000 died, and I put in a new WRT 1900AC to replace it.  In the process of getting things set up correctly the main "network name" in my network displays shows up as a name assigned to a Wireless portion of my network.  The "Wired" portion shows up in diagrams, and to windows, as well as both of the main wirless bands but not as the central node between either of the wired Win7 computers and the internet  I would like to get the Windows 7 machines on my network to display the wired network name in Windows 7 as the primary network, and NOT one of the wireless ones.  Almost everything I want to be able to do is working just fine except for the network map display in Windows 7 where I have been trying to configure a "home group" that will not yield to my efforts., 
I use "suffix" notation in the naming, so my router on ethernet is .<ame>..NET, the wireless lower band is <name>...W24 upper band is <name>...W5.   I have not figured out how to get the artifacts of the "setup sequence of events" out of the Windows 7 displays in "network neighborhood" so I have a more rational picture that has Ethernet at the core and the wireless bands as additional subsidiary networks not necessarily associated with all my devices.  I know this is not technicallly a Linksys issue, but... Can I simply delete alll the neworking information in Windows 7, and reboot, and then force the computer to set up a network based on the correct network node labels. provided by the router?   I'm a bit worried that I might have to "reset" everything which would be a huge **bleep** since almost all of what I want to do is working just fine, I'm just not quite clear some times whether the process of connecting from one computer to another, or to a NAS attached to the router is going through the wired network or the wireless one where performance can be a big issue.  My Ethernet is "certified" at 1gbps which is a lot faster than the wireless networking.  Sometimes it seems that accessing the NAS attached to the router is being done "through a tiny straw, not the fast pipe in the wiered world.  I used to do a lot of NETBIOS networking in Windows "back in the day" and my network naming conventions have probably not kept up with the times, but I still have two Windows XP computers wired into my household network, and when "debugging" things I think of the Ethernet as central and the wirless portions as additional networks, not the other way around.  Unfortunately Windows 7 seemed to grab the wireless names first, probably because the machines in question both have wireless and wired connectivity built in and available in their hardware and the one that was set up and working with the old router when the new one got plugged in was used to do the initialization initially using the default sequence built into the router software.  I was able to go back and rename everything to get rid of the default names, but my Android based network monitor only works within range of the router and not when the phone is connected to the internet outside of the house.  I've never been able to get the phone support folks to help me clear that issue up either. ..  When I added the second computer, the same thing happened out of the box, Windows took the name of the first wireless network it found and put it into the network neighborhood as the device in the path between the new computer and the internet,   I can "see" the host name of the router correctly from everywhere, and map to the 1TB disk I have hung on it from all of my computers, but the Internet connection is actually an ethernet drop from a cable modem to an ethernet port on the router, not to either of the wireless bands that show up.

@zundapman Hi! What's the current firmware of your router? Make sure that your firmware is up to date with the latest version. Also, are you referring to the Windows explorer's map or the User Interface map of the router or the Network and sharing map of your computer?
