As a follow on to my thread about IP address changing and disconnects I would like to get some advice on ADSL modems.
Currently I am using a D-LINK DSL-G604T, which I suspect may be the cause of the problems I am experiencing.
I have a TP-Link W8960N, but it also raises some issues: my son maintains that a number of the sites he uses cease to function or function very slowly when we use the TP-Link, and it does take a while to establish a connection when it is first set up.

Based on what I've read the ZyXEL Prestige 660M looks a good bet bet it does not seem to be readily available in NZ.

I'd be grateful for any input, advice or info.

Thanks in advance.
