Hi. . .
bcmwl63a.sys is a Broadcom wifi driver - https://www.sysnative.com/drivers/driver.php?id=bcmwl63a.sys
Check for an update at your system manufacturer's (OEM) support site. Broadcom itself does not update their own drivers. They only do so for OEMs.
It's not unheard of for new systems to need driver updates as these new systems can sit on store shelves for quite a long time. Meanwhile, drivers are updated while the system is on the shelf.
My suggestion - take the system back (it is brand new after all) and get a different system with an Intel wifi. Intel always keeps their drivers updated; Broadcom and Atheros do not.
I am able to run Windows 10 on a Vista-era system (2008) because it has an Intel wifi adapter and Intel has kept the wifi drivers updated. No way would Windows 10 work on the system if I had Broadcom or Atheros wifi as there would likely be no wifi drivers available. Windows 10 may work just fine, but not the wifi.
It is of course your call here, but if me -- I would take the system back and get one with an Intel wifi adapter so that future Windows OS' will likely function on it.
Regards. . .
