google translated to ENGLISH you said, (i hope)
"After having done
all the checks with the router and the cpu connection and having tried other computers the problem is the following: every time I turn on the computer I have to restart to be able to surf the internet, and once restarted I can surf but not before . So the problem must be with the motherboard. I would appreciate a solution, as it is very annoying." AND COMMON !
NO OS TOLD AT ALL AND MATTERS FIRST.
XP,VISTA , 7? WHAT? OS IS THERE.
upgrading any OS past what Asrock allows gets you dead , LAN AND DEAD SOUND. (and more)
answer, 1:
tried other computers<<< and what happened on them.?
all the same or only 1 PC fails and not told ethernet or wifi connected. so answer are super hard, but i bet Ethernet works other PCs cabled to router.
the CPU has no LAN, sorry, the mobo does have LAn CALLED ETHERNET.(wired). and the chip is known, (in the manual)
no lan told.(wifi or wired)
there is no wifi on this mobo, so must be this, wired below.
Realtek PHY
RTL8201CL
- Speed: 10/100 Ethernet (slow kind)
to use this chip on thIS MOB\O BOARD, WE must load the driver first from asrock (using a 2nd PC to fetch it and put it on dead lan PC)_
the drivers are frozen at XP/ VASTA OS. LONG AGO 2006 YEAR.
LOAD ALL 6 DRIVERS SEE HERE. (PICK OS FIRST)

ELSEWHERE YOU GET A VIRUS, I PROMISE, BESIDES BELOW.
OR IF LUCKY DIRECT FROM CHIP MAKER
HERE THE 81-nnnn driver is no good for 81. so finding it here is not easy.
