Roku not connecting to internet but my internet is perfectly fine

 ##It's very simple why my #Roku Ultra (4670 series) will not connect to wifi.    ROKU devices do not support WPA3.  My new 802.11ax access points do not support any encryption less than WPA3 with exception of WPA2-SHA256 and certificate authentication.  But that whole problem is irrelevant now after my ISP switched to IPv6 only back in Nov.   ROKU can't use IPv6.   

However, on a side note the education network I work for is switching to IPv6 only in March. Our network has almost 3,800 roku devices which will be renderred useless across the campus network.  We will be referring all them to Roku Support after the switch.

My Roku was/is telling me it not connected to the internet but it does say my signal strength is excellent, and all the other devices in the house are working perfectly and say my signal strength is excellent.

I followed all the different advice: I have restarted Roku. That didn't work. I restarted my Wi-Fi but unplugging the router and waiting and having all of the other other devices in the home have to go through that.

Then I did a factory reset on roku, which did not help one bit and was a terrible mistake because now I'm going to have to upload all the different apps again... If my Roku ever works again. This is probably just something Roku does after a little while to make you purchase a new device. I've had to do that before. But last time, I was able to talk to Roku and they fixed it..

And then I went ahead and restarted my router again because I restarted Roku and then did the router reset, and I figured it would be a good idea to do the router reset again, after having done the factory reset on roku.

I'm still without working TV.

I realize I'm going to call Roku tomorrow and hopefully they will do whatever it is they did on their end last time that will make this work.
