“Roku goes thru the wireless router/modem.”
Which is why I just said they suck. Because they took away the choice to Hard wire.
Not sure what your issue is with them. I have been happy with the switch.
As far as hard wire, not sure I really understand the reason you want to hard wire...
This is what I got. Not expensive and it has held up so far—one for 1.5 and one for 1 year. They don’t “suck.”
