No connection

Hello all

Got my pc connected to a router
That router have 3 pc wired to it
& bunch of wifi connections

All PC & wifi devices
Got connection
All but my PC
Not even the light over my cable connected to the router… is ON… like the other PC cables…

& i dont think my cable is stepped on or damaged
Since its out of the way

Could an ad virus do this?
Or anyone came at some point with similar problem & fixed it…?
I did a malware scan & blocked some results…
but still…

UPDATE:
nvm
had a net splitter
with its power train…
to split 1 internet cable from the router to multiple PCs…
it was broken … after around 5years of use…

my bad…
