Hello Patrick
The term "Smart Managed Plus functions" actually says it all. Furthermore, in order to be able to use VLAN sensibly, you must also be able to configure the switch. The information regarding Management at Digitec is incorrect.
It is difficult to give a general answer because we do not know what your infrastructure looks like. In this respect, I hope for your understanding. You are welcome to try the following solutions:
- Check if you have installed the latest firmware.
- Try the following settings:
IGMP snooping status - enabled
VLAN ID - do not set
Validate IGMPv3 IP header - disabled
Block unknown multicast address - disabled
Static router port for IGMP snooping - here you enter the number of the port where your router/modem is connected.
If this does not help either, or if these functions are not available, I recommend that you contact Swisscom or Netgear.
