I was under the impression that your router was the Fedora 23 box - now 
this is making a little more sense.  I notice you're using custom 
firmware on those devices and it makes me wonder whether they might play 
a role in some way.

The next thing I would try would be to wire the Fedora system and one of 
your other devices to the router and see if a router reboot affects the 
connectivity between the system and the device.  This procedure 
simplifies the problem set by removing the wireless piece of the 
puzzle.  If rebooting the router affects connectivity between the two 
wired devices, then you might have a problem with the router's switch.  
To confirm this you can substitute a simple switch for the router, 
connect both the system and the device to it, check connectivity, reboot 
the switch and check connectivity again - rebooting the switch should 
have no effect and the systems should be able to interact with each 
other consistently.

If rebooting the router doesn't affect the connectivity of the wired 
system and another wired device, then the problem might be with the 
router's wireless capability and possibly with how the system and other 
devices interact with it.
