Thanks for the post.
We would recommend checking out our Support page regarding your device showing Low Signal Strength here: What should I do if I see the "Low signal strength" message?
I've run into this here several times. This has always worked for me:
If that doesn't fix it, try disconnecting the power to your Roku for a few seconds. When it comes back up, see if you then can set up the network connection.
