@matutedamaris38 you didn't actually say anything, so we don't know what issue you're having.
If the subject line is accurate, then you might be experiencing something that has occurred with numerous TCL TVs. The antenna connection on the WiFi board comes loose and needs to be resoldered to the board. Not something that can be done by the average owner. Contact TCL and see if you can get some support from them. Roku did not build your TV, so they can't assist with hardware issues.
