Roku will not connect to EAP245 AC1750 AP
I have just bought an EAP245 AC1750 Access Point to replace an aging Linksys device running DD-WRT. The unit I received is, somewhat to my surprise, a V1 model. After configuring the unit it works perfectly and all my devices (around 12) can connect to either 2.4Ghz or 5Ghz. The one exception is a Roku 3. Whatever I do config wise, it will not connect to either band. It always fails with a Roku error 014 30. The AP is running firmware 1.4.0 Build 20180323 Rel. 32551(4555).
If I swap back my old AP, the Roku connects immediately. While this appears to be an issue with the Roku, I only have a limited time to fix the issue or reluctantly return the AP.
Any advice welcomed.
