I have an IPTV service from BT here in the UK. Their service uses IGMPv3.
When my IPTV box is connect to my RUT240 I cannot receive their TV service. If I bypass the RUT240 and connect directly to my ADSL service I can receive their TV service.
I once had a similar problem with a network switch that didn't support IGMPv3.
Does anyone know if the RUT240 supports IGMPv3?
Thanks - James
