Hi Scott378,
I'm sorry to hear that you are having issues accessing your Roku. I would advise to try changing the following system rules for the firewall. To access the system rules, please click the settings 'cog' icon on the upper right-hand side of the Firewall screen > click the "System Rules" button on the Settings screen:
1. Please set the "Allow Windows File and Printer sharing" option to "Enabled"
2. Please set the "Allow remote desktop connections to this computer" option to "Enabled"
If you are still having issues accessing the Roku from the PC after changing these settings, please try changing the following Geek Area settings for the firewall. To access the Geek Area, please click "Search" in the top right of the Settings screen (if you still have the system rules options showing, please close this window) > type geek:area in the text box and press enter/return > click "Search" in the top right of the screen > type Firewall and press enter/return.
1. Please enable "Internet Connection Sharing mode" (click the box to the right of the setting so that a green tick appears).
2. Please enable "Allow all connections with Friends when in Private mode"
3. Please disable "Enable automatic profile switching"
4. Please disable "Enable automatic port scan detection"
