Hi @mukesh140,
Welcome to the Roku Community!
Thanks for letting us know about the behavior you are seeing with your Roku Streaming stick that keeps disconnecting from your home network and we appreciate the troubleshooting steps you've done so far.
Can you please verify when did this issue first start occurring? Have you tried moving the device closer to your router to see if you can get connected?
To isolate the issue, have you tried to connect your device to an alternate network, such as a mobile hotspot to see if there is a difference?
We look forward to hearing from you and looking closely into this issue. Thank you!
Best regards,
Mary
