Every time I turn on the TV and switch from cable to Roku, I get a "Roku Not Connecting" message. I have to restart the router and the Roku system to get it to work. This is really annoying. Anyone else have this problem?
What's the model number of the Roku device displayed under Settings->System-Power?
If applicable, are you using the TV's USB port to power it?
Does it have a "power saving" option under Settings->System->Power? If so, try disabling it.
Just encountered the same problem after switching to Cox Panoramic latest Wifi 6 protocol device, last Friday. All 4 of my Rokus ( Express, simple remote, 0- 3 years old Rokus) now disconnect each time they are turned off for more that a few hours. Never had a disconnection problem before ( with 5 year old modem). Everything else i.e. all other connected devices perform much better with faster speed. Have to go though the multi step process of rebooting the Rokus each use. Not acceptable.
(not using USB to power, plenty of signal everywhere in the house ( much more than with old router)..
(Have tried to give 5GHz band a separate SSID, does not make any difference.)
Try configuring the 2.4ghz band to use b/g/n under the Wireless Mode/Protocol setting in 2.4ghz Wireless Settings and see if both the disconnection and stubborn reconnection issues are now resolved with the Express devices.
