Roku Ultra Wont Connect to Wifi after 12.5.0 build

I have a Roku Ultra 4800 and 4802. After the most recent firmware update to 12.5.0 they no longer work properly. They will not connect to the Roku server as the time no longer shows up in the upper right corner. The Hulu, Amazon Prime, AppleTV, and YouTube apps no longer work. I have uninstalled and reinstalled the apps several times and that doesn't work. Netflix, Paramount+, Disney+ all work fine.

I have reset the modem and the router on multiple occasions and sometimes that works and sometimes it doesn't.

The only thing that does work consistently is factory resetting the Roku's AND the modem and router and after a few tries everything works for a few days and then it starts over.

I recently upgraded to fiber internet but all my other devices are connected fine and I have no connectivity issues.

    Verify that your router is not using "DFS Channels" (52-140) under your 5ghz Wireless Settings.  Roku cannot currently see or use DFS so either need to Disable DFS usage if you currently have "Auto" set under Wireless Channels, or manually set the 5ghz to use a channel between 36-48, or 149-161.

    If you find that your router is not using DFS, then try lowering the Bandwidth/Channel Width in your 5ghz Wireless Settings to 80mhz, and see if that helps. (many fiber setups are set to 160mhz and can cause issues with Roku devices as it narrows the available channel selection to the network).

    I would also check with ISP to see if your 2.4ghz band is Enabled.  This would at least give you an alternate network band to connect to when you experience a 5hz disruption.  However, manually configuring the 5ghz band to the above settings should help minimize the disruptions.

    Feel free to post back with ISP and router model number if still having issues.

      After I reset everything last night it still didn't work but my settings were 2.4 and 5 GHz bands were separated and the Roku's were set to the 5GHz band with the DFS channels disabled.

      When I got up this morning everything was working and is still currently working. The wireless settings are still on automatic to switch between 80 and 160MHz.

      The ISP is i3 Broadband and the router is a a TP-Link AX10000 with the latest firmware offered by TP-Link.

      The Roku's still have build 12.5.0 4178-C2 as they did yesterday.

      Nothing else was changed between last night when it didn't work and today when it did however this has happened before and works for a few days and then has issues again.

        This has been communicated with the appropriate Roku team, and they are currently investigating this.

        We'll make sure to forward any update here, once we have it available.
