I wanted to connect my PC with notebook through LAN cable (CAT5-568B, also tried few others with 4 wires) . On PC side i use win10 and i set IP to 192.168.0.30, Mask 255.255.255.0 and on notebook side i use win7 with IP 192.168.0.50 and Mask 255.255.255.0. I disabled firewalls on both side, but just before I did that i add rules that would allow icmp4 and icmp6 echo requests and allow UDP protocol to be established on all local ports and any IPs, in private or public networks. I disabled AVs on both PCs. Tried to ping in both ways but most of the time i get host unreachable. I installed wireshark on both pcs and one of the symptoms i could see is that my PC is sending broadcast messages, but notebook is not replying. When i try to ping from notebook i dont see broadcast messages. Tried pinging themselves and it is working for both pcs. I would really appreciate some suggestions ^_^ I tried many things beside from this, but couldnt explain them because some solutions i found on internet and they didnt work.
