Hi Arul, thanks for reporting this.

Do you know if this problem happened after a specific kernel update? The best would be to identify also a good kernel that can properly detect your wifi adapter and touchpad. If we have a good kernel and a bad kernel we can bisect the changes and easily identify which commit introduced the problem. Thanks!
