I have a new Wifi6 router and connected my Roku Stick 3600 X to it. About 30 to 60 seconds after connecting the remote stops working. If I take the batteries out of the remote and then put them back in, it will work for 30 to 60 seconds again then stop. Can keep doing constantly. Occurs on both 2.4 and 5 GHz. If I switch it back to the old router everything is fine. I have a Roku 4 in another room and it works fine connecting to the new router. Any recommendations?
