Hi,

That LED flashing is likely intentional. All the Realtek-based wireless adapters I own do that to indicate an active wireless connection.

Were you maybe using an older driver version previously? Do you remember the version you've had originally installed?

I noticed that Microsoft just recently put the Realtek driver version 5001.15.129.0 on Windows Update. So it's possible that it may be auto-updating to that driver version.

Personally I tame such annoying LED's by putting either a small sticker or small piece of adhesive tape on top of it or paint over it with a permanent marker pen.
 

  @woozle An auto update could have caused it. I do not know my previous or current version as everything auto updates.

Putting a sticker on top will be my solution then. Thank you for the suggestion.

With best regards,
Dylan
