You can try disabling any built-in security for the router:
1) Turn off any ad-blocker
2) Turn off: firewall/turn it to the lowest setting, Network Service Filter
3) Turn off: AiMesh, AiProtection Pro, Malicious site blocking, 2 Way IPS, Infected Device Prevention and Blocking
4) See if Roku connects
That would make sense. The Roku is functioning properly when I switch to mobile hotspot. the only outlier is Asus at this point. I was on the phone with their level 1 technicians and they could get it to work with all the different system settings changes either. Of course, now Asus are digging deeper and will get back to me about the issue.
I just ordered a Roku Ultra. It arrives today. I will see if the 5Ghz band works. If not I will use ethernet while Asus troubleshoot on their end.
I Will definitely update you with the resolution.
The Roku is functioning properly once I transfer to cell hotspot. The best outlier is Asus at this point. I changed into on the cellphone with their degree 1 technicians and they might get here to paintings with all of the unique machine settings modifications either. Of direction, now Asus are digging deeper and will get returned to me about the problem.
Any resolution to this? .. I have the same issue where my Roku Streaming Stick+ won't see my 5Ghz SSID, but it will see my 2.4Ghz and connect to it. Of course I'd rather have it connect to the 5Ghz.
Worked fine on my old ASUS AC3200 router. Where I now see this issue is with my new ASUS RT-AX82U WiFi 6 Router. I tried disabling WiFi 6; setting the 5Ghz radio from AUTO to B/G/N (Haven't tried N only though); tried turning on 160Mhz and AUTO DLC(sp?) - At one point my 5Ghz SSID DID show up on the Roku, but when I went to sign in, it failed connecting. It did recognize that it was password protected.
There HAS to be some setting combo that I'm missing.
@Devereiii831, check the 5GHz channel your router is using. If it's set to "Auto", change it to a fixed channel 49 or below or 150 or above.
That fixed my issue. I set the channel above 150 and it worked.
