[OS 11.5] Wi-Fi Keeps Jumping To 2.4Ghz

Ever since OS 11.5.0 build 4216-50, my 3810X - Roku Streaming Stick+ jumps to the 2.4Ghz band at times.  Prior to the OS update, it always stayed on 5Ghz.  I have a Linksys EA8300 AC2200 Tri Band Router. 

I can tell when it is on 2.4Ghz because things run slower and then I check Settings > Network > About and see it is on a 2.4Ghz channel.  Serial number YH0097428140, Device ID C13799428140.

    Roku Support helped me out.  Ended up being my device.  I purchased a new device, and it has not jumped to 2.4GHz band at all.

    That particular Linksys router supports both band-steering (automatically placing devices on best determined network connection) and also the use of DFS channels on the 5ghz band.  This router supports use of DFS channels 52-64 and 100-140.

    Since Roku cannot see or use DFS channels (52-144), either disable the use of them in your router (which it may be selecting, thus causing the 5ghz connection to drop and then automatically switch to the 2.4ghz band), or manually assign a wireless channel to the 5ghz band 36-48 or 149-161.

    Otherwise, that router also allows you to configure Guest Networks that do not support band steering.  Whatever band you place it on, it will stay and not seek the other band automatically.  Again, make sure you are using a non-DFS channel for the 5ghz band. 

    ----

    So, a few options for you.

    1. Disable Band Steering and use seperate 2.4 gzh and 5ghz bands and Disable DFS channel usage. 

    This will allow to Roku connect to 5ghz and will not fall back or switch to 2.4 ghz w/o interaction from you.

    2. Keep Band Steering Enabled and Disable DFS channel usage.

    This will allow Roku to connect to 5ghz and will fall back to 2.4ghz when router determines this is a better connection.

    3. Use the Guest Network 5ghz and again, Disable DFS channel usage.

    This will allow Roku to connect to 5ghz band and not switch to 2.4ghz w/o interaction from you.

    ----

    To Disable DFS, either go to your router's Wifi Settings/Advanced/DFS/ [Disable] or manually assign a  wireless between 36-48 or 149-161.

      That is not an acceptable solution more so a workaround. 

      I have many other devices that use band steering and I do not wish to reconfigure my network just to appease a change in the Roku OS.  I have used my existing configuration for many years without issue. 

      I want Roku to fix it back to when it used to work fine.

      I did turn off band steering as a test, but my Roku is still acting up, it is not moving to 2.4G, but its disrupting 5G is why my router is most likely penalty moving it to 2.4G.  I repeat, it just started this after the 11.5.0 update.

        This is not a workaround. These are network configuration options.

        Just to clarify, "devices" do not use Band Steering.  This is a feature of a mesh router system that will automatically place a device on the band the "router" determines is best.

        Did you verify that you are not using DFS channels in your 5ghz setup?
