ok , what OS came on this new?
for sure dont use w8, as the wifi engine it it is JUNK totally junk from
MS.com
i see Asus offered a free w10 upgrade, google searched 1st hit.
says clear as day, not all features work, if done
why not just leave it at w7 ?
1st and always,
connect the PC directly from PC ethernet jack cable to router
now the web works, and now the magic PNP works
microsoft plug and play works, so does that cure the dead wifi chip?
i can not know what chip is inside your PC for wifi, as the makers uses like 5 kinds even on one model. (what's on sale i guess.?)
but they do.
so only drivers for that unknown chip work
in a real shop we run app called PCI-z, or the like.
and see what chip it is then if the chip is dead, we get the driver from
ASUS direct or from the chip maker, like say broadcom.
here are the correct paths in order
1:MS PnP autoloaded driver,
2: Asus driver off their set
3: chip makers driver
only those work and only those are virus free, ok? 1,2,3. only
there is 1 exception but lets skip that, for now.
if the ethernet cable fails, that is very bad, and very rare.
for sure w10, plug and play on modern PCs supports all ethernent
your support site is here
https://www.asus.com/us/Laptops/X551CA/HelpDesk_Download/
the ATK fixes, w10 compat. issues.
asus does not disclose what chips are on the mobo , in there lame spec,page, (par)
but we have tools do that , in all cases. so.... spec be damned.
look at that page, you see all drivers are missing there
this is like marketing ploy, (goons) that can communicate facts.
it should say at the top, this.
"ALL drivers for this product not seen below are at ms.com"
did you install w10
64bit fresh (not 32 !!!)
and did the ethernet cable run from PC to router
if not OOP that was wrong, that 1st step.
let the installer reach the MS servers,
here that server is if curious.

connect ethernet to PC RJ45 to router, cat 5 cable is ok,
then boot the DVD< w10 or ISO built uSB stick.
now fresh load w10-64bit, and all chips in the PC should hit the deck running. ok?
