Hi Sid,
Thank you for the update on the issue.
I totally agree with you that if you bring close to the router it will work fine. A wireless network router has a limited broadcast range. The further the computer is from the router, the weaker the broadcast signal. Solid objects, such as walls, metal furniture, and electrical appliances might interfere with the signal and decrease the usable range.
Feel free to post your query on the forum if you have any concern related to Windows.
Regards.
