Demeter: Hi Froob,

Have you tried using a Vodafone Broadband Complete modem? Does this improve your SureSignal service or not at all? I have found this list of devices which are known to perform well with SureSignal.

The following things may affect your service stability on your SureSignal device:

Internet Connection – Minimum Bandwidth
Vodafone sure signal requires a minimum 1 Megabit downstream and 300 Kilobit upstream data rate to operate successfully.

Internet Connection –Stability
Each time Sure Signal loses internet connectivity it will take between 5 – 10 minutes for the device to re-establish a connection with the Vodafone Network. During this time no calls / data sessions can be made using the Sure Signal device.

Network Configuration – Router/Firewall
Vodafone Sure Signal requires an IPSec compatible router with ports 8, 50, 500 and 4500 open for incoming and outgoing traffic.

Network Configuration – DNS
If using internal DNS and/or Proxy servers ensure that
initial-ipsecrouter.vag.vodafone.co.nz is added to the DNS records and/or allowed access via the Proxy Server.

Network Configuration – DHCP enabled
Vodafone Sure Signal cannot be configured with a Static IP address and requires DHCP enabled.

Network Configuration - Changes
- If using a non Vodafone Internet connection, has the Internet connection IP (WAN IP) changed?
- Have any of the Vodafone Sure Signal devices been moved to a different location?
- Have you added / removed a Vodafone Sure Signal device


Hope this helps a bit,
Lon
