We recently installed a Cisco Aironet 1252 access point. This access point replaced a home class device (linksys). The problem is that the Cisco seems to be block multicast traffic coming from the Ethernet LAN.
This is essential, as an auto diagnostic tool resides on the (wired) LAN that the mechanics connect to from their wirelessly connected laptops. The software can ONLY find the device if the multicast from the diagnostic tool is found. While they cannot open the software and find the tool from it, we can ping the (known) IP address.
I need to know, if possible, how to configure the AP to allow this multicast traffic.
FYI, the diagnostic tool remains hard wired to the LAN. I can connect to the device from the laptops while connected with a cable to the LAN, OR while connected to a temporary access point(linksys). It is definitely the Cisco blocking this traffic.
We have a pretty generic config on the AP. Both 2.4 and 5 GHZ radios are enabled with external antennas, WPA/WPA2 AES+TKIP encryption.
If anyone neesd more info or config, let me know what will help and I'll get it posted.
