Initially I set up my Roku express to my projector and managed to connect it to my WiFi without any issue. It worked fine until it was turned off and on again. It says it is not connected and although it is showing a list of possible network connections, mine is no longer included. I moved the Roku and connected it to my TV which is right next to my router, I reset my router and I reset the Roku. I checked my WiFi frequency and it looked like it was set at both 5GHz and 2.4GHz so I changed it to 2.4GHz after reading similar topics but still my network has not become available. Has anyone else experienced this? Thanks.
