Hi,
I have a streng situation.
I can ping IP address of WLC and AP from LAN.
Also the PC connected through WiFi is responsible but of every one minute is discarded one ICMP packet.
This situation is not only to one PC but on others connected to WLAN.
When I connected to PC on WiFi the situation is the same.
Ping from this host to WLC, AP and others IP address to LAN is discarded every one minute.
