Be aware that, following the install of 9.3 firmware, express and premier units are no longer able to detect 5GHz networks, Check for 2,4GHz channel connectivity or turn off steering if your 5G router is dual-band. Hope this helps.
I can only say what worked for me and I really hope that someone finds this in the comments or a reply because I didn’t know how to comment in here and I’m sorry I have been on the phone all day with on Ryukyu hotline they sent me all around the world but when I finally got to the person, this is what they told me to do and it worked my Internet would not connect at all. It was not the Internet. It was the TV MAC address which is an hardware faulty, is what I was told. I tried everything in the comments nothing worked, so I finally had to bite the bullet and call Roku hotline. I’ll unplugged the tv then I press the power button on the TV actually for 60 seconds, then plug the TV back up and go to your Wi-Fi connection and it should work it did for me to save time from calling the hotline and being on it all day, and if you’re like me, who restarted your whole system it let me put my apps back on through my phone instead of individually doing it on tv I have a ONN ROKU TV 50” I hope this helps someone
My Roku Ultra hadn't updated firmware in over a year. With the assistance from a Roku support rep, I solved my issue with wireless connectivity by plugging an Ethernet cable from my network switch into my Roku Ultra and it immediately performed a firmware upgrade to the latest version. After the Ultra rebooted, I disconnected the Ethernet cable and successfully connected to my WiFi network and haven't had any issues since.

I don't know who you called, but Roku does not offer phone support. Many web sites offer to support Roku, but they are usually trying to steal your user account information. If you called such a number, I strongly suggest you log into your Roku user account and immediately change your password.
I know all about scammers. I was sent an email directly from a Roku support rep and given a toll free number to call and given a trouble ticket number. I was never asked for any personal info or payment info. The rep gave me the info to try and it fixed the problem.
I'm still leery. I have never heard of Roku offering a toll free number. Now, perhaps they've finally improved their tech support. I'm very glad your issue is resolved. But I still recommend watching your account, and any credit cards you have linked to your account.
