    The Router is an Asus RT-AC66U dual band gigabit router. I have not found a place where the user manual is directly accessible online but can be downloaded from ASUSTeK Computer Inc. -Support- Drivers and Download RT-AC66U Unfortunately, the user manual does not even mention the DMZ.
    There is a manual that specifically deals with the DMZ at ASUSTeK Computer Inc. -Support- In my case the DMZ is NOT turned on.
    I tried one more experiment: I connected via a wired connection and mapped a drive on the NAS. I then logged off and re-connected using a wireless connection: "The network path was not found" - Strange!
    I am still not convinced the router is at fault here: If the "Wireless Network Watcher" can see those devices, they are obviously on the network, working, and discoverable. The wireless network watcher doesn't just make that information up. (interestingly, all the missing devices are actually connected via wired connections rather than wireless)
    If the devices are working and are discoverable, the router must be doing its job. The fact that I can see those devices if I use a wired connection, also seems to confirm that the router is doing its job.
    In my opinion, the problem likely is somewhere on the Windows 8 machine - specifically some setting or some driver that has something to do with the wireless connection.

    I'm curios, after you did the firmware update, did you set the router back to defaults then perform a reset, this is sometimes required to get firmware updates to work correctly. Mostly all good reviews on your router.

    About the only complaints I saw with this router was the firmware updates were doing some strange things unless you reset the router to defaults after the update, but nothing specifically about wireless devices having access problems.

    I've never had a problem with my Windows 8 machine seeing other wireless devices and don't know of any special settings to allow for this.

    That's one thing I did not try. I'll give that a shot when I have time. Unfortunately that won't be until at least tomorrow.
    One other thing, in case you're curious: Until earlier today I had been connecting via the 5GHz connection. I just switched to the 2.4GHz connection and it is doing the same thing.

    I was wondering about trying 2.4GHz or 5GHz but looks like that isn't the problem.

    I'm more curious about what the actual problem might be here and looking forward to some type of resolution.

    If you have any type of third party Anti Virus software or firewall installed, that would be my next choice for causing this problem.

    I followed your suggestion and re-set router to factory settings, manually set it up again, rebooted, etc. and still nothing! (Well - "something": two unknown cell-phones had somehow snuck onto the network in that brief moment when it was unprotected. I explicitly blocked those using MAC address filtering)
    Somewhat peeved, I shut off each and every device that had anything to do with computers and gave them a rest. Several hours later I started powering devices on again: modem, router, switches, print server, W7 machine, XP machine, NAS, W8 machine. Now - big drum roll - ALL devices were showing BUT for some reason the NAS, while visible, was not actually accessible.
    Since access to that device is vital, I started over:
    I again shut off everything and gave it a bit of a rest. I then powered everything on again. Now comes the disappointing part: all the "questionable" devices (XP machines, NAS, Print Server) had disappeared again and no longer showed up in Explorer. In other words, my moment of triumph had only lasted for a very brief period of time and I am right back to where I started.
    I tried one other thing: I installed a copy of Cisco's "Network Magic Pro" (This software is no longer available). It had no problem finding all devices on the network and drawing a network map.
    Also: The W8 machine has no 3rd party AV or firewall - just whatever comes with Windows 8 ("Defender")

    For the NAS access problem the first link I posted might get you in, if that is still a problem.

    About all I can suggest is a router reset and trying again as that seems to be the only thing working.

    Those cell phones it picked up might just be your own phones, Windows can pick them up even if they are not connected to your network.

    I hope those aren't managed switches you are using.

    * LAN Manager authentication level was already set to LM & NTLM responses only
    * I can't find the setting to turn off require 128-bit encryption but I am certain I already turned it off.
    * The switches are not managed switches.
    * The cell phones were definitely not mine (I gave up cell phones the day I retired - now people actually have to SPEAK to me) but they are gone now so: no worries.
    * I re-set the router again. This time I saved the router configuration file and just re-loaded it after the re-set. I rebooted everything and now, again, I can see all devices on the Windows 8 machine. Unfortunately the NAS is still not accessible. The error message from the Windows Network diagnostics is: "Windows cannot communicate with the device or resource. It is available but is not responding to connection attempts. A firewall or network security policy on the remote computer might be blocking the connection on port "file and print sharing resource".
    This "resource" is a QNAP 559 Pro II (See QNAP, Inc. - Network Attached Storage (NAS) - Products - Products - Archive - Storage - 5-Bay - TS-559 Pro II). As far as I know, it is running SAMBA. I never had to fiddle with it for the NAS to be visible in XP or W7. I sent a message to QNAP support - hopefully they will come up with a solution.

    I'm about to give up for now: The bleeping devices have disappeared again. I refuse to reset the router every time I shut down the Windows 8 machine.

    One further development: I had sent an inquiry to Gigabyte, the manufacturer of my motherboard asking them about the "Download Center" utility that is packaged with my board and is supposed to give me the latest and greatest drivers. This utility did not work properly for me forcing me to hunt down and install drivers manually.
    The answer I received was: "Download Center is currently not supported under Windows 8, please download all Windows 8 drivers manually off our website." I had already downloaded the drivers but that did not resolve my problems. I am currently running the machine via a hard-wired connection as everything seems to working fine that way. Connected wirelessly I can still not see all devices. Worse, even the ones I do see may or may not actually be accessible. I have officially declared the wireless connection "flakey" but I would still dearly love to figure out what is at fault here and how it can be fixed. So if anyone reading this has any ideas, I encourage you to leave a post with any trouble-shooting tips you may have.

    I think the issue has got nothing to do with either router or other devices, it's one of Widnows 8's "glitchs".

    Try this solution:

    1 Go to Control Panel - View Network Status and tasks, choosing the active wireless network you're using
    2 Click "Change advanced sharing settings"
    3 Expand the "Guest or Public" options
    4 Set both items to "turn on..." option.
    5 Save and restart your PC.

    Let me know if it works.
