I have three Roku's in my home, one is an Ultra and the other two are Roku Express. All three worked fine. I fell asleep with the bedroom Roku on and woke up to it saying it wasn't connected to the internet. I kept messing with it, I unplugged and reset the router, I unplugged the Roku, I did a system reset, I even did the home button 5 times and did something to disable ping. I looked everywhere for how to fix it. The Ultra in my living room works fine, no issues. The two Express devices will not connect. I have wi-fi connectivity on my phone, on my Alexa device and even on my laptops. However, it will not connect on the two Roku Express. I have tried just about everything. I don't understand how everything else works, but not these two devices. It finds my network, it says I have excellent signal strength but it will not connect to Wi-Fi. Also to note, I tried connecting the two Express devices via my hotspot on my cell phone and they work then but they won't connect through my actual home wi-fi. Can anyone help me?
