If you are using a RokuTV (as opposed to a seperate Roku device), make sure your "booster" is configured to use n/AC (wifi5) as well as AX (wifi6). If allowed in configuration, also make sure that you are using WPA2 as well as WPA3. (this is just an authentication standard/protocol normally located in the wifi settings under "security")
RokuTV and Roku devices do not currently support AX standards (which use WPA3 authentication), so any wifi6(ax) access point/extender/router/booster has to be configured to allow wifi5 standards (hence, enabling n/AC and WPA2).
Feel free to post back some info on your AX equipment and can look into the specs for you.
