I have a very strange problem.
Computers can't ping each other on the same network.
In the labs at the College we use LanSchool and the teacher was unable to check students computers. When I check I did a simple ping from the teacher computer to a student computer and was unable to ping it.
I tested several other computers on the same lab and no computer can ping the other.
They are all using DHCP and connected to an AP (Cisco Aironet 1250). They all use a wireless card.
I check the firewall setting on our server and ICMP is allowing ech request and nothing is blocking that so I really don't understand what should be the next step to check what is going on.
I even tried Wireshark and I can't seem to ping to any other external IP exept the servers.
Internet connection is working ok tough.
