Hi
I am investigating internet connection reliability using a Mini PCIe 3G/UMTS/HSPA module module on the Vodafone NZ Network (No problems on XT!). The problem is the the connection appears to "go to sleep" when no traffic goes over it for a while. I understand it drops back to UMTS from HSPA when the link is idle. It is just that it doesn't "wake up" very quickly when I want to send data. This was demonstrated by a ping taking 2minutes to get a reply. (The ip address is Vodafones DNS server)

At other times the ping time varies hugely.

Is this just me or is it just what you get using Mobile Broadband. I am using the APN "internet" if that makes a difference.
Are different settings required for a PC type connection rather than a phone connection?
