Probaj ovo, otvori konzolu i kucaj ping 127.0.0.1
ako dobijeĆĄ Packets: Sent=4, Receive=4, Lost=0 "lan karta" radi, ali ako dobijeĆĄ Packets: Sent=4, Receive=0, Lost=4 verovatno je neispravna, poĆĄto je laptop, sumnjam da moĆŸe da se zameni.
Ugasi WIFI dok ovo probaĆĄ.
a probaj i ovo, direktno ga poveĆŸi kablom sa nekim drugim kompom
Ping your system's IP address: To further troubleshoot network adapter issues, you can connect the system directly to another system or a client via a crossover cable or dumb-hub. Setup TCP/IP using two consecutive addresses (e.g. 10.1.1.1 and 10.1.1.2) and use the default subnet masks (255.0.0.0). From a command prompt, try to Ping the client IP address. If the system gets a response, the network adapter is fine.
