I haven't tried anything hardwired to my router at this point, but I'll probably keep on monitoring the router's activity right now.
I might often suffer any drop in activity or so and that's why I often have to do a hard reset (unplugging the router and plugging it back in) on my router - as a "stop gap" measure.
That problem doesn't occur everyday but on "certain times". Right now, everything seems to be "stable" at this point.
I'll probably keep you posted if anything arises.
