Any chance you can get directly connected with the PCs to the router instead of the NG switches? Your network isn't working to best speeds with using 100mb switches since the router supports 1000Mb speeds. Your limiting your network performance.
A recommendation would be to get into some Gb supporting switches instead of using 100Mb switches.

If your using default DHCP IP address pool on the router 192.168.0.100 thru .199, set your PCs up outside of the pool like this:
192.168.0.2 thru .99. Set these IP addresses on each PC. Subnet mask will be 255.255.255.0 and gateway will be 192.168.0.1 and DNS can be 192.168.0.1 or actual ISP DNS addresses seen under Status/Wan section. Disable DNS Relay.

Just wanted touch up on this.

Our network is still deteriorating in performance. Now we're down to only seeing two computers over the entire network (the 2 windows 10 computers).
Windows 7 computers Crystal-pc, Curtis-pc, Central-pc have always been directly hooked to the router NOT through a switch and still drop out of network view randomly with the other machines.

One workaround that I have been doing for the past month was to restart the central-pc computer on a daily basis. This resulted in EVERY computer on the network showing up perfectly under network view for the duration of the day. The next day I would reboot central-pc again and same result. I do not know why this is like this but it was working for a month consistently. towards the end of the May though, the network would loose views of the other computers and ultimately rebooting did not do anything.
 
We recently acquired some wireless printers which I added to the network wirelessly but they too also disappear from network view unless there is a power failure and the router is rebooted.

I think this router is bad. Just wondering if you've ever had similar experience?

Only thing I'm thinking is that this one Windows 10 PC seems to be possibly causing issues on the network and something with this PC and the router is not working well together.

Just trying to remember here if we had you factory reset the router, re-load FW, then reset once more then set up from scratch?
Might try going back to v1.04 and test. Someone said v1.04 has fixed something for them recently that the most current FW broke. 

I think the next step maybe would  be to see if you can get into a different D-Link router if you can and test something different out. While this is happening, you could take the 826L home put it in a different location to see if the problem follows. Then you'll know for sure. Check out either a local shop or an online e-tailor that has a refund policy. OfficeDepot/Max carries a 15 day policy. I just demo'd the DIR-885L from there then took it back as I didn't need to keep it. LOL

If there is a price point or budget you have, I can recommend something.

I've never experienced this issue on my network with any of my routers including the 826L and have numerous devices connected.

wow forgot about this thread.

just wanted to update, over the summer I took the router in to the place we bought it since I had purchased extended warranty with it and they kept the router for a week trying to replicate other computer disappearing under their network views in windows and they could not find anything wrong with the router.

I've since shifted to looking at the network here and am trying to learn about master browser polling and election. Seems like if a computer that is always on maintains its master browser status longer than 4 hours, the other pcs will lose the other computers under network views. If i reboot the pc that currently has master browser status, it will then go to another computer and the network will show ALL computers fine.

Can anyone offer suggestions as to how to go about fixing this? I don't know why my network is disappearing when one computer holds the master browser status "too long." If I reboot that machine, master browser goes to another computer and everything works fine... until after a certain amount of time.
Very frustrating.

This computer that keeps the master browser too long Windows 10?
I wast thinking that the last posts you mentioned that one PC if it was rebooted the network PCs were displayed. I'm thinking this one PC maybe the root cause.

Might want to start looking into this:
