Cisco DPC3925

details: DOCSIS 3.0 Wireless Gateway with Embedded Digital Voice Adapter
hardware type: Cable Gateway
date added: 2010-05-06
updated: 2012-08-21
The DPC3925 is a DOCSIS 3.0 certified wireless cable router with four 10/100/1000Base-T LAN ports, a single USB port and two FXS ports for VoIP. The DPC3925 provides a faster connection to the Internet by incorporating eight bonded downstream channels along with four bonded upstream channels. These bonded channels can deliver downstream data rates in excess of 340 Mbps and upstream data rates in excess of 120 Mbps.

The integrated AP complies with IEEE 802.11n standard. It is WDS compatible and supports WMM (QoS) to prioritize the traffic over the network. A WPS button allows for easy wireless security configuration.

The DPC3925 provides VPN pass-through for IPSec and PPTP. A built-in SPI firewall protects the network against hackers and Denial of Service (DoS) attacks.

This would have been a decent modem integrated wifi-router but for a critical flaw, which cisco has acknowledged BUT WILL NOT FIX - multicast over wifi does not work - preventing modern services such as airplay, dlna, itunes sharing to fail.

I have the same problem... And so do plenty of others. It does not support uPnP/DLNA over wireless, so is a joke for Cisco in 2012 that it does not support it at all. Nearly pulled my hair out trying to figure out why on earth my Synology NAS (or any device for that matter) wasn't working properly...

i suggest using this router with a el cheapo wireless router plugged into to it and set up as access point will solve all your problems :P if you dont know how to do it google it takes like 2-3 minutes

There is absolutely o words to describe the appalling performance of this modem and router. You had a router and realise that the signal is not stable. Called many time Starhub and they changed the modem for me but this new one is perfuming as poorly as the previous one.
Do not upgrade the services provided by star hub, change provider. I have heard, unfortunately too late, that Singtel is providing a very fast and reliable service.
