I have a roku tv in my dorm room (college student) and it doesn’t have an Ethernet port, so I bought an Ethernet-USB adapter. However my tv doesn’t connect to the Ethernet when I plug it in, I must restart the tv for it to connect. Is there any way to fix this? The same Ethernet cable and USB adapter works perfectly on my laptop. I cannot use the university WiFi on the tv unfortunately, as it’s for mobile devices and computers.
It sounds like your tv is connecting to wifi through USB (attached adapter). I'm surprised that works at all.
It doesn't sound like there's a way to make it better. (Maybe setup your laptop to be a hotspot, then connect with the tv's native wifi to the laptop.). Otherwise, the menu restart (home>settings>system>power) sounds like it wouldn't be too bad (considering I wouldn't have even expected the usb connectivity to work).
