Slow speed and IP address change in Modem Mode



I have recently purchased a Cisco RVS4000 VPN Router and I have a slight problem I wish an expert to help me with.


At home I have a 100Mbps internet connection which gets a result of around 80-98Mbps on the .  However, when use the RVS4000 with the Superhub in Modem mode I can only achieve 20Mbps downstream and 9Mbps upstream.   I am using Cat 6 cabling for everything with Gigabit ports.  The QoS / bandwidth settings are disabled on the new device.  The Cisco is set in Gateway mode as opposed to Router mode.


Also, when I switch to modem mode my IP address changes to a VM 82 range address


Any ideas what could be causing the slow down and is the IP address change normal?

If it has IPS enabled try disabling it.

Believing is catch 22 the VMDG280 should never of been made the Super hubs 1 & 2 could have been built better the years go by and we can't see the mistakes that were made to make things right. Use modem mode If I could offer you only one tip for the future, modem mode would be it. BQM, Outgoing ports test
