Help & troubleshooting for network issues, including connecting your device to your home Wi-Fi network, connecting to public networks, troubleshooting wireless issues & ethernet connections, and optimizing streaming performance.
Forgive me if this is a double posting: I posted once, but did so before logging in and fear it may not have "taken". Here it is.
I have a Synology RT2600AC router which was connected to the Roku and functioning perfectly.
In order to be able to discriminate between the 2.4GHZ and the 5GHz networks, I slightly changed one digit in each of their SSID names. I changed one SSID so that it now ends in the numeral 2 and the other SSID so it ends in the numeral 5.
I went back to the Roku, deleted the old SSID name, input the new one, used the same password and the Roku keeps returning a big red X and won't connect.
I reset the Roku and the problem persists.
I did a reset, unplugged the Roku, the TV, and the router, waited two minutes and turned them all on again: still the problems persists. The Roku 3 simply will not accept/recognize the slightly changed SSID name. We are A B S O L U T E L Y sure we are inputting the correct SSID name and password.
I wish there were some pinhole on the ROKU into which one could insert a bent paper clip and do a complete reset as I suspect some cache continues to retain the old SSID settings and won't accept that new name.
There is a small, hidden recessed button to do a factory reset. But before you do that, go into the Settings menu and look under advanced settings for a Network Reset function. Then try connecting to your WiFi again.
