Hello,I have a LAN with about 120 PCs, in the last 2 weeks I am facing a problem, the network sometimes go very slow and sometimes the users cannot reach the internet ( the router will be unreachable) and I have to restart the router and the switches, So I am starting using wireshark, Is this traffic in the picture normal? If No, what is the solution? asked 25 Sep '16, 22:40 said_othman |
