Basically right click your network connection and go properties.
Double click on Internet Protocol (TCP/IP)
You will be presenting with this screen:

Now put the dot in the radio box that says: Use the following IP address.
Set your ip address manually (note mine is setup for use in NZ i dunno about the auzzies :))
Note: the DNS entries i have are for Xtra.
I know this is a relativly simple thing to do but it fixed my issue i have not had any drops for about 10 days now.
It was not posted in the other thread so i thought id post it here as it may help others who were affected.
Cheers.
